No Traffic Control

Arm of T-junction
If Model S detects a T-junction based on the map data, Model S slows down and
comes to a complete stop at the red stop line displayed on the instrument panel.
When you want to proceed, you must take over steering and acceleration.
WARNING: Model S may not stop at a T-junction that does not have a stop sign
or stop line, or if the T-junction is not included in the map data. Drive
attentively and be prepared to stop (when necessary and/or appropriate).

End of T-junction
Model S slows down and comes to a complete stop at the red stop line displayed on
the instrument panel. When you want to proceed through the intersection, you must
pull the Autopilot stalk toward you or briefly press the accelerator pedal.
NOTE: If you confirm that you want to proceed through an intersection controlled by
a stop sign by pulling the Autopilot stalk toward you or briefly pressing the
accelerator pedal before Model S has stopped, your confirmation is ignored. Model S
is not designed to proceed through a stop sign without stopping.
NOTE: Even when using Autosteer, and even if you have engaged a turn signal, you
must turn the steering wheel yourself (which cancels Autosteer) to complete a turn
at an intersection.

WARNING: Model S also slows down and stops at a roundabout. You must take over steering (which cancels
Autosteer) and pull the Autopilot stalk toward you or briefly press the accelerator pedal to confirm that you
want to continue through the roundabout.
WARNING: At crosswalks, Model S may slow down and may stop, depending on whether the crosswalk is
controlled by a traffic light and whether the cameras detect pedestrians, bicyclists, etc. in the crosswalk. Pay
particular attention at crosswalks and be prepared to take over at any time. Failure to do so can result in injury
or death.
Limitations
Depending on many different circumstances and environmental conditions, Traffic Light and Stop Sign Control may
or may not stop at:
• Railroad crossings.
• Keep-out zones.
• Toll booths.
• Crosswalk systems.
• Yield signs or temporary traffic lights and stop signs (such as at construction areas).
• Miscellaneous traffic U-turn lights, bicycle and pedestrian crossing lights, lane availability lights, etc.
In addition, Traffic Light and Stop Sign Control is particularly unlikely to operate as intended, can disengage, or may
not operate, when one or more of the following conditions are present:
• Driving through consecutive light-controlled intersections that are very close to each other.
• Visibility is poor (heavy rain, snow, fog, etc.) or weather conditions are interfering with camera or sensor
operation.
• Bright light (such as direct sunlight) is interfering with the view of the camera(s).

166

Owners Manual
• A camera is obstructed, covered, damaged, or not properly calibrated.
• Driving on a hill or on a road that has sharp curves on which the cameras are unable to see upcoming traffic lights
or stop signs.
• A traffic light, stop sign, or road marking is obstructed (for example, a tree, a large vehicle, etc.).
• Model S is being driven very close to a vehicle in front of it, which is blocking the view of a camera.
WARNING: The limitations listed above are not an exhaustive list of reasons why Model S may not operate as
expected. Many unforeseen circumstances can adversely impact the accurate operation of Traffic Light and
Stop Sign Control. Using this feature does not reduce or eliminate the need to drive attentively and
responsibly. You must be prepared to take appropriate and immediate action at all times.

167

Owners Manual
Autopark
NOTE: Depending on market region, vehicle configuration, options purchased, and software version, your vehicle may
not be equipped with Autopark.
Autopark uses data to simplify parking on public roads by maneuvering Model S into parallel and perpendicular
parking spaces.
CAUTION: Ensure all cameras and sensors (if equipped) are clean. Dirty cameras and sensors, as well as
environmental conditions such as rain and faded lane markings, can affect Autopilot performance.
WARNING: Autopark's performance depends on the ability of the cameras and sensors (if equipped) to
determine the vehicle's proximity to curbs, objects, and other vehicles.
WARNING: Do not use Autopark if anything, such as a ball hitch, bike rack, or trailer, is attached to the tow
hitch. Autopark may not stop for hitches when parking between or in front of other vehicles.
Parameters
Autopark detects potential parking spaces based on the following parameters:
Perpendicular Parking
• Your driving speed must be below 8 mph (13 km/h). If driving too fast, Autopark may not be able to accurately
detect your desired parking space.
• The parking space must be at least 7.2 feet (2.2 meters) wide.
• The parking space must have at least three visible lines for the vehicle to park into, such as parking lines, road
markings, or distinct curbs. Autopark may not work in a garage, for example, without three visible parking lines.
• Autopark may not work with textured road surfaces such as cobblestone or brick.
Parallel Parking
• Your driving speed must be below 13 mph (21 km/h). If driving too fast, Autopark may not be able to accurately
detect your desired parking space.
• There must be a vehicle in front of the space you want to park in.
• A distinct curb or edge must be visible. Autopark may not correctly identify the parking space if the curb is not
distinct, such as grass or dirt.
NOTE: Autopark does not operate on angled parking spaces.
Parameters
Autopark detects potential perpendicular parking spaces that are at least wide with a vehicle parked on each side.
Your vehicle speed must be below 13 mph (21 km/h) for parallel parking spaces, and 8 mph (13 km/h) for
perpendicular parking spaces. If driving too fast, Autopark may not be able to accurately detect your desired
parking space.
NOTE: Autopark does not operate on angled parking spaces.
To Use Autopark
When driving, follow these steps to allow Autopark to maneuver Model S into a parking space:
1. While driving slowly on a public road, monitor the instrument panel to determine when Autopark has detected a
parking space. The instrument panel will display a parking icon if the vehicle detects a potential parking spot.

168

Owners Manual

NOTE: The parking icon appears only if the vehicle's position and/or the circumstances of the surrounding area
are such that Autopark can determine an appropriate driving path. If Autopark cannot determine an appropriate
path (for example, when driving on a narrow street where moving into the parking space causes the front of the
vehicle to extend into the adjacent lane), you can either reposition the vehicle, find a different parking space, or
park manually.
NOTE: If the Autopark icon does not appear for potential parking spaces when driving at the indicated speed, it is
possible that Autopark is calibrating. Autopark requires a calibration process when Model S is new, or when tires
have recently been changed (see Calibration on page 169).
2. Check to determine if the detected parking space is appropriate and safe. Pull forward and stop approximately
one car length ahead of the parking space (as you normally would when parallel parking or when backing into a
perpendicular parking space).
3. Release the steering wheel, shift Model S into Reverse, then touch Start Autopark on the touchscreen.
4. Autopark displays a message when parking is complete.
NOTE: If you press the brake pedal when Autopark is actively parking Model S, the parking process pauses until you
touch Resume on the touchscreen.
WARNING: Never depend on Autopark to find a parking space that is legal, suitable, and safe. Autopark may
not always detect objects in the parking space. Always perform visual checks to confirm that a parking space
is appropriate and safe.
WARNING: When Autopark is actively steering Model S, the steering wheel moves in accordance with
Autopark's adjustments. Do not interfere with the movement of the steering wheel. Doing so cancels Autopark.
WARNING: During the parking sequence, continually check your surroundings. Be prepared to apply the
brakes to avoid vehicles, pedestrians, or objects.
WARNING: When Autopark is active, monitor the touchscreen and instrument panel to ensure that you are
aware of the instructions that Autopark is providing.
Calibration
During a parking sequence, Autopark must maneuver Model S with a great deal of precision. Therefore, before it can
be used, Autopark must complete a calibration process. Calibration can take anywhere from 30 minutes to several
days, depending on driving behavior. When Autopark is calibrating, a note displays on the Autopilot settings screen
indicating that calibration is in progress. When calibration is complete, this note no longer displays and Autopark is
available for use.
NOTE: Autopark repeats the calibration process whenever tires are changed.
To Pause Parking
To pause Autopark, press the brake pedal once. Model S stops and remains stopped until you touch Resume on the
touchscreen.
To Cancel Parking
Autopark cancels the parking sequence when you manually move the steering wheel, shift, or touch Cancel on the
touchscreen. Autopark also cancels parking when:
169

Owners Manual
• The parking sequence exceeds seven moves.
• Model S detects that the driver is exiting the vehicle.
• A door is opened.
• You press the accelerator pedal.
• You press the brake pedal while Autopark is paused.
• An Automatic Emergency Braking event occurs (see Collision Avoidance Assist on page 180).
Limitations
Autopark is particularly unlikely to operate as intended in these situations:
• The road is sloped. Autopark is designed to operate on flat roads only.
• Visibility is poor (due to heavy rain, snow, fog, etc.).
• The curb is constructed of material other than stone, or the curb cannot be detected.
• The target parking space is directly adjacent to a wall or pillar (for example, the last parking space of a row in an
underground parking structure).
• One or more of the sensors (if equipped) or cameras is damaged, dirty, or obstructed (such as by mud, ice, or
snow, or by a vehicle bra, excessive paint, or adhesive products such as wraps, stickers, rubber coating, etc.).
• Weather conditions (heavy rain, snow, fog, or extremely hot or cold temperatures) are interfering with sensor (if
equipped) operation.
• The sensors (if equipped) are affected by other electrical equipment or devices that generate ultrasonic waves.
WARNING: Many unforeseen circumstances can impair Autopark's ability to park Model S. Keep this in mind
and remember that as a result, Autopark may not steer Model S appropriately. Pay attention when parking
Model S and stay prepared to immediately take control.

170

Owners Manual
Summon
NOTE: Depending on market region, vehicle configuration, options purchased, and software version, your vehicle may
not be equipped with Summon, or the feature may not operate exactly as described.
Summon allows you to automatically park and retrieve Model S while you are standing outside the vehicle. Summon
moves Model S forward and reverse up to 39 feet (12 meters) in, or out of, a parking space.
To move Model S a longer distance while steering around objects, you can use Smart Summon (if equipped) and
your mobile phone. Smart Summon allows your vehicle to find you (or you can send your vehicle to a chosen
location). See Smart Summon on page 174.
CAUTION: Ensure all cameras and sensors (if equipped) are clean. Dirty cameras and sensors, as well as
environmental conditions such as rain and faded lane markings, can affect Autopilot performance.
WARNING: Summon is designed and intended for use only on parking lots and driveways on private property
where the surrounding area is familiar and predictable.
WARNING: Summon is a BETA feature. You must continually monitor the vehicle and its surroundings and stay
prepared to take immediate action at any time. It is the driver's responsibility to use Summon safely,
responsibly, and as intended.
WARNING: Summon's performance depends on the ability of the cameras and sensors (if equipped) to
determine the vehicle's proximity to objects, people, animals, and other vehicles.
Before Using Summon
Before operating Summon, use the touchscreen to enable it and customize how you want it to work. Touch Controls
> Autopilot > Customize Summon and adjust the following settings to suit your preferences:
• Bumper Clearance: Set the distance that you want Summon to stop from a detected object (for example, you
may want Summon to stop within just a few inches of a garage wall). Note that this distance applies only to
objects that Summon detects directly in front of Model S when moving forward, or directly behind Model S when
reversing.
• Summon Distance: Set a maximum distance that Model S can travel when entering or exiting a parking space.
• Side Clearance: Choose an option to specify how much side clearance you want to allow. Tight allows Model S to
enter and exit very narrow parking spaces.
WARNING: Parking in a narrow space limits the ability of the cameras and sensors (if equipped) to
accurately detect the location of obstacles, increasing the risk of damage to Model S and/or surrounding
objects.
• Require Continuous Press: By default, Summon requires that you press and hold a button on the mobile app to
move Model S during the parking process. When Require Continuous Press is set to No, you can press and
release the button—you don't need to hold it down to keep the vehicle moving. Also, when Require Continuous
Press is set to No, you can operate Summon using the key fob instead of the mobile app (see Operating Summon
with the Key Fob on page 172) and you can start a parking sequence from inside the vehicle (see Starting
Summon Before Exiting the Vehicle on page 173).
• Use Auto HomeLink (if equipped): Set to ON if you want to activate HomeLink to open/close a programmed
HomeLink device (such as a gate or a garage door) during the parking process when using Summon. If enabled,
the device automatically opens and closes when Model S enters or exits during a Summon session. In a Smart
Summon session (if equipped), the device automatically opens when, at the beginning of a session, Smart
Summon detects that Model S is parked in a garage.
WARNING: Always ensure that Model S is fully in or out of a garage before HomeLink lowers the garage
door. Summon and Smart Summon (if equipped) cannot detect where an overhead door will lower.
NOTE: When enabled, the HomeLink device automatically opens and closes when using Summon, and
automatically opens as needed when using Smart Summon (if equipped). To automate HomeLink in other
situations (such as normal driving), you must adjust the HomeLink device's main settings by touching the
HomeLink icon at the top of the touchscreen (see Smart Garage on page 88).

171

Owners Manual
NOTE: The above settings, with the exception of HomeLink, apply only to Summon—not Smart Summon (if
equipped) (see Before Using Smart Summon on page 174). You cannot customize Smart Summon's bumper
clearance, distance, and side clearance. And when using Smart Summon, you must always hold down the button on
the mobile app to keep Model S moving. Also, Smart Summon operates with the mobile app only—not the key fob.
NOTE: All settings are retained until you manually change them.
Using Summon to Park and Retrieve your Vehicle
Follow these steps to use Summon to park your Model S:
• Align Model S within 39 feet (12 meters) of the parking space so Model S can follow a straight path into or out of
the space in either Drive or Reverse.
• From outside the vehicle, initiate the parking maneuver by touching Summon on the mobile app, then holding
down the Forward or Reverse button.
NOTE: If the Require Continuous Press setting is No, you do not need to hold down the button, just press and
release.
NOTE: You can also initiate the parking maneuver from inside the vehicle (see Starting Summon Before Exiting
the Vehicle on page 173).
Summon shifts Model S into Drive or Reverse (based on the direction you specified) and drives into or out of the
parking space. When parking is complete, or if an obstacle is detected, Summon shifts Model S into Park. Summon
shifts Model S into Park when:
• Model S detects an obstacle in its driving path (within the Bumper Clearance setting that you specified).
• Summon has moved Model S the maximum distance of 39 feet (12 meters).
• You release the Forward or Reverse button (when Require Continuous Press is turned on).
• You press any button to manually stop Summon.
If you used Summon to park Model S, you can then use Summon to return Model S back to its original position
(provided Model S has remained in Park), or to the maximum Summon Distance that you have specified (whichever
comes first). Simply specify the opposite direction on the mobile app and Summon moves Model S along the original
path, provided no obstructions have been introduced. If an obstacle is detected, Model S attempts to avoid the
obstacle while staying very close to its original path (Summon does not steer around obstacles).
NOTE: To use Summon to move Model S multiple times in the same direction (not to exceed the maximum of 39 feet
(12 meters), cancel Summon and then restart the parking process using the same direction.
NOTE: Although Summon can move Model S a short distance laterally to avoid an obstacle, it does not attempt to
steer around an obstacle to return Model S to its original driving path. Only Smart Summon (if equipped) can steer
Model S around objects.
NOTE: Summon requires that Model S can detect a valid key nearby.
WARNING: Model S cannot detect obstacles that are located lower than the bumper, are very narrow, or are
hanging from a ceiling (for example, bicycles). In addition, many unforeseen circumstances can impair
Summon's ability to move in or out of a parking space and, as a result, Summon may not move Model S
appropriately. Therefore, you must continually monitor the vehicle's movement and its surroundings and
remain prepared to stop Model S at any time.
Operating Summon with the Key Fob

NOTE: Summon may not operate if the battery is low on the key fob.
Follow these steps to park Model S from outside the vehicle using the key fob:
1. On the touchscreen, ensure that Require Continuous Press is disabled (touch Controls > Autopilot > Customize
Summon > Require Continuous Press).
2. With Model S in Park, stand within 10 feet (three meters) and press and hold the top center button on the key fob
(Lock/Unlock All button) until the hazard lights blink continuously.

172

Owners Manual
NOTE: The hazard lights flash once as Model S locks, then within five seconds, Model S powers on and the hazard
lights flash continuously. Do not proceed to the next step until the hazard lights are flashing. If, after five seconds,
the hazard lights are not flashing, release the button on the key fob, move closer to Model S, and try again. If
Summon receives no further input within ten seconds, Summon cancels.
3. Press the Front Trunk button on the key fob to move Model S forward into the parking space, or press the Rear
Trunk button to reverse Model S into the parking space.
Starting Summon Before Exiting the Vehicle

To start a Summon parking sequence before exiting Model S:
1. On the touchscreen, ensure that Require Continuous Press is disabled (touch Controls > Autopilot > Customize
Summon > Require Continuous Press).
2. Close all doors and trunks.
3. With Model S powered on and Park engaged, double press the Park button on the drive stalk. The touchscreen
displays a popup screen.
4. On the touchscreen, choose the direction of travel.
5. Exit Model S and close the driver's door.
Summon now moves Model S according to the direction you specified on the touchscreen.
NOTE: To cancel the parking maneuver before exiting the vehicle, touch Cancel on the popup screen.
NOTE: If you do not choose a direction of travel on the touchscreen, Summon does not start a parking maneuver
when you exit.
Stopping or Canceling Summon

Stop Model S at any time while Summon is active by using the mobile app or by pressing any button on the key fob.
Summon also cancels when:
• A door handle is engaged or a door is opened.
• You interact with the steering wheel, brake pedal, accelerator pedal, or shift.
• Model S detects an obstacle.
• Summon has moved Model S the maximum distance of approximately 39 feet (12 meters).
• Your phone enters sleep mode or loses connectivity to Model S.
Limitations
Summon is unlikely to operate as intended in the following types of situations:
• The driving path is sloped. Summon is designed to operate on flat roads only (up to 10% grade).
• A raised concrete edge is detected. Summon does not move Model S over an edge that is higher than
approximately 1 in (2.5 cm).
• One or more of the sensors (if equipped) or cameras is damaged, dirty, or obstructed (such as by mud, ice, or
snow, or by a vehicle bra, excessive paint, or adhesive products such as wraps, stickers, rubber coating, etc.).
• Weather conditions (heavy rain, snow, fog, or extremely hot or cold temperatures) are interfering with sensor
operation.
• The sensors (if equipped) are affected by other electrical equipment or devices that generate ultrasonic waves.
NOTE: Summon is disabled if Model S is in Valet mode (see Valet Mode on page 132).
WARNING: The list above does not represent an exhaustive list of situations that may interfere with proper
operation of Summon. It is the driver's responsibility to remain in control of Model S at all times. Pay close
attention whenever Summon is actively moving Model S and stay prepared to take immediate action. Failure to
do so can result in serious property damage, injury or death.

173

Owners Manual
Smart Summon
NOTE: Depending on market region, vehicle configuration, options purchased, and software version, your vehicle may
not be equipped with Smart Summon, or the feature may not operate exactly as described.
Smart Summon is designed to allow you to move Model S to your location (using your phone's GPS as a target
destination) or to a location of your choice, maneuvering around and stopping for objects as necessary. Smart
Summon works with the Tesla mobile app when your phone is located within approximately 213 feet (65 meters) of
Model S. Smart Summon maneuvers Model S out of parking spaces and around corners. This is useful for moving
Model S out of a tight parking spot, through puddles, or helping you retrieve your car while carrying packages. You
must maintain a clear line of sight between you and Model S and closely monitor the vehicle and its surroundings at
all times.
CAUTION: Ensure all cameras and sensors (if equipped) are clean. Dirty cameras and sensors, as well as
environmental conditions such as rain and faded lane markings, can affect Autopilot performance.
WARNING: Smart Summon is designed and intended for use only on parking lots and driveways located on
private property where the surrounding area is familiar and predictable. Do not use Smart Summon on public
roads.
WARNING: Smart Summon must only be used on paved surfaces.
WARNING: Smart Summon is a BETA feature. You must continually monitor the vehicle and its surroundings
and stay prepared to take immediate action at any time. It is the driver's responsibility to use Smart Summon
safely, responsibly, and as intended.
WARNING: Smart Summon may not stop for all objects (especially very low objects such as some curbs, or
very high objects such as a shelf) and may not react to all traffic. Smart Summon does not recognize the
direction of traffic, does not navigate around empty parking spaces, and may not anticipate crossing traffic.
WARNING: Smart Summon's performance depends on the sensors (if equipped), the visibility of the cameras,
and the availability of an adequate cellular signal and GPS data.
WARNING: When using Smart Summon, you must maintain a clear line of sight between you and Model S and
stay prepared to stop the vehicle at any time by releasing the button on the mobile app.
Before Using Smart Summon
• Download the latest version of the Tesla mobile app to your phone, and ensure your phone has cellular service
and GPS enabled.
• Your phone must be connected to Model S and located within approximately 213 feet (65 meters).
• The vehicle's cameras must be fully calibrated (see Drive to Calibrate Cameras on page 138).
• You must have a clear line of sight to Model S.
• Model S must be in Park, not charging, and all doors and trunks must be closed.
Using Smart Summon
1. Open the Tesla mobile app, and press Summon.
2. Press the Smart Summon icon located in the center of the image of your Model S. It may take several seconds for
Smart Summon to start up.
NOTE: You can use Standby Mode to eliminate the delay that occurs when Smart Summon is starting up (see
Standby Mode on page 175).
The mobile app displays a map with a blue circle, which represents the maximum proximity of 213 feet (65
meters) that you must maintain between your phone and Model S. The blue dot on the map represents your
location, and the red arrow represents the vehicle.
3. Position yourself anywhere within the blue circle where you have a clear line of sight to Model S.
4. You can now operate Smart Summon using either of these modes:
◦ Come to Me mode: Press and hold the Come to Me button. Model S moves to your GPS location. As you move,
Model S follows you. When Model S reaches you, it stops and shifts into park.
174

Owners Manual
◦ Go to Target mode: Touch the crosshair icon then drag the map to position the pin on a chosen destination.
Press and hold the Go to Target button. Model S moves to the destination. When reaching the location,
Model S stops and shifts into Park and the mobile app displays a message indicating that Summon has
completed.
NOTE: To subsequently change the location, lift your finger, reposition the map, then press and hold Go to
Target again.
To stop Model S at any time, simply release the Come to Me or Go to Target button.
The map's crosshair icon toggles between Go to Target and Come to Me modes. When Come to Me
mode is selected, the icon is blue.
NOTE: The map also has an icon that allows you to display/hide satellite imagery.

Immediately after initiating Smart Summon in either mode, hazard lights briefly flash, mirrors fold, and Model S shifts
into Drive or Reverse. Model S then slowly moves to within 3 feet (1 meter) of you (Come to Me) or your chosen
destination (Go to Target), navigating obstacles as needed. As Model S moves, the corresponding red arrow on the
map also moves to show the vehicle’s location. As you move, the corresponding blue dot also moves to show your
location.
In either mode, Model S stops moving and shifts into park when:
• You release the button on the mobile app.
• The maximum proximity between your phone and Model S is exceeded (if moving the vehicle to a destination
away from you, you may need to follow the car to maintain this distance).
• The driving path is blocked.
• Model S has moved the maximum distance of 475 feet (145 meters) since the start of the Smart Summon session,
or has moved 492 feet (150 meters) away from the location from which the vehicle was last driven manually.
NOTE: If Smart Summon moves Model S forward three feet and then backwards two feet, this is considered five
feet of travel.
NOTE: There is no need to look at the mobile app—just hold down the button while keeping your eye on Model S and
its driving path at all times, remaining ready to release the button to stop the vehicle if needed.
If equipped and Auto HomeLink is enabled for Summon (touch Controls > Autopilot > Customize Summon > Use
Auto HomeLink), Smart Summon automatically opens a HomeLink device if you start the Smart Summon maneuver
when Model S is located inside a garage. The mobile app informs you that the door has opened.
WARNING: When you release the button to stop Model S, a slight delay occurs before the vehicle stops.
Therefore, it is critical that you pay close attention to the vehicle’s driving path at all times and proactively
anticipate obstacles that the vehicle may be unable to detect.
WARNING: Use extreme caution when using Smart Summon in environments where movement of obstacles
can be unpredictable. For example, where people, children or animals are present.
WARNING: Smart Summon may not stop for all objects (especially very low objects such as some curbs, or
very high objects such as a shelf) and may not react to all oncoming or side traffic. Pay attention and be ready
to stop Model S at all times by releasing the button on the mobile app.
Standby Mode
To keep Model S ready to Summon and reduce the time it takes to warm up, turn on Standby Mode. Touch Controls
> Autopilot > Standby Mode. When Standby Mode is turned on, you can conserve Battery energy by disabling
Standby Mode at these locations:
• Exclude Home - Disables Standby Mode at the location you set as Home in your Favorites list.
• Exclude Work - Disables Standby Mode at the location you set as Work in your Favorites list.
• Exclude Favorites - Disables Standby Mode at any location in your Favorites list.

175

Owners Manual
NOTE: To conserve energy, Smart Summon automatically exits Standby mode from midnight to 6:00 am. During
these hours, a delay occurs as Smart Summon starts up.
NOTE: Additional battery power may be consumed while Standby Mode is active.
NOTE: For details on how to designate a location as Home, Work, or Favorites, see Home, Work, and Favorite
Destinations on page 203.
Stopping or Canceling Smart Summon

session, simply press the Come to Me or Go to Target button again.
WARNING: Always anticipate when you need to stop Model S. Depending on the quality of the connectivity
between the phone and Model S, there may be a slight delay between when you release the button and when
the car stops.
Smart Summon cancels, and requires you to restart it, when:
• You press any button on the key fob.
• A door handle is engaged or a door is opened.
• You interact with the steering wheel, brake pedal, accelerator pedal, or shift.
• Model S is blocked by an obstacle.
• Smart Summon has moved Model S the maximum distance. To move further than this distance, you must shift
Model S into Drive or Reverse and then re-initiate a Smart Summon session.
• Your phone enters sleep mode or loses connectivity to Model S.
Limitations
Smart Summon is unlikely to operate as intended in the following types of situations:
• GPS data is unavailable due to poor cellular coverage.
• The driving path is sloped. Smart Summon is designed to operate on flat roads only (up to 10% grade).
• A raised concrete edge is detected. Depending on the height of the concrete edge, Smart Summon may not
move Model S over it.
• One or more of the sensors (if equipped) or cameras is damaged, dirty, or obstructed (such as by mud, ice, or
snow, or by a vehicle bra, excessive paint, or adhesive products such as wraps, stickers, rubber coating, etc.).
• Weather conditions (heavy rain, snow, fog, or extremely hot or cold temperatures) are interfering with sensor (if
equipped) or camera operation.
• The sensors (if equipped) are affected by other electrical equipment or devices that generate ultrasonic waves.
NOTE: Smart Summon is disabled if Model S is in Valet mode (see Valet Mode on page 132).
WARNING: The list above does not represent an exhaustive list of situations that may interfere with proper
operation of Smart Summon. It is the driver's responsibility to remain in control of Model S at all times. Pay
close attention whenever Smart Summon is actively moving Model S and stay prepared to take immediate
action. Failure to do so can result in serious property damage, injury or death.

Active Safety Features

176

Owners Manual
Lane Assist
Model S monitors the markers on the lane you are driving in as well as the surrounding areas for the presence of
vehicles or other objects.
When an object is detected in your blind spot or near the side of Model S (such as a vehicle, guard rail, etc.), the
instrument panel displays colored lines radiating from the image of your vehicle. The location of the lines correspond
to the location of the detected object. The color of the lines (white, yellow, orange, or red) represent the object's
proximity to Model S, with white being the farthest and red being the closest and requiring your immediate
attention. These colored lines only display when driving between approximately 7 and 85 mph (12 and 140 km/h).
When Autosteer is active, these colored lines also display if driving slower than 7 mph (12 km/h). However, the
colored lines do not display if Model S is at a standstill (for example, in heavy traffic).

CAUTION: Ensure all cameras and sensors (if equipped) are clean. Dirty cameras and sensors, as well as
environmental conditions such as rain and faded lane markings, can affect Autopilot performance.
WARNING: Lane Assist features are for guidance purposes only and is not intended to replace your own direct
visual checks. Before changing lanes, always use side mirrors and perform the appropriate shoulder checks to
visually determine if it is safe and appropriate to change lanes.
WARNING: Never depend on Lane Assist to inform you if you unintentionally drive outside of the driving lane,
or to inform you that there is a vehicle beside you or in your blind spot. Several external factors can reduce the
performance of Lane Assist (see Limitations and Inaccuracies on page 179). It is the driver's responsibility to
stay alert and pay attention to the driving lane and other road users. Failure to do so can result in serious injury
or death.
Steering Interventions
Lane Assist provides steering interventions if Model S drifts into (or close to) an adjacent lane in which an object,
such as a vehicle, is detected. In these situations, Model S automatically steers to a safer position in the driving lane.
This steering is applied only when Model S is traveling between 30 and 85 mph (48 and 140 km/h) on major roads
with clearly visible lane markings. When a steering intervention is applied, the instrument panel briefly displays a
warning message.
Lane Departure Warning
Lane Departure Warning alerts you of undesired lane departures by slightly vibrating the steering wheel if a front
wheel passes over a lane marking when the associated turn signal is off. To turn this warning on or off, touch
Controls > Autopilot > Lane Departure Warning. Lane Departure Warning is active only when driving between
approximately 40 and 90 mph (64 and 145 km/h).
Lane Departure Avoidance
Lane Departure Avoidance is designed to warn you if Model S is drifting out of, or nears the edge of, your driving
lane.

Lane Departure Avoidance operates when driving between 40 and 90 mph (64 and 145 km/h) on roads with clearly
visible lane markings. You can choose if and how you want Lane Departure Warning to operate by touching Controls
> Autopilot > Lane Departure Avoidance and selecting between these options:
• Off: You are not warned of lane departures or potential collisions with a vehicle in an adjacent lane.
• Warning: If a front wheel passes over a lane marking, the steering wheel vibrates.
• Assist: Corrective steering is applied to keep Model S in a safe position if Model S drifts into an adjacent lane or
near the edge of the road.
When Lane Departure Avoidance is enabled and Traffic-Aware Cruise Control is active, if Model S drifts out of the
driving lane when the associated turn signal is off, Lane Assist also checks to see whether your hands are on the
steering wheel. If hands are not detected, the instrument panel displays a series of alerts, similar to those that are
used when driving with Autosteer. If hands are repeatedly not detected Model S gradually slows down to 15 mph (25
km/h) below the detected speed limit, or below the set cruising speed, and the hazard lights start flashing.
NOTE: Lane Departure Avoidance does not warn you of lane departures, or provide steering interventions, if the
associated turn signal is on, which indicates an intentional lane change.
WARNING: Lane Departure Avoidance is intended to help keep you safe, but it does not work in every situation
and does not replace the need to remain attentive and in control.
WARNING: Keep your hands on the steering wheel and drive attentively at all times.
WARNING: Steering interventions are minimal and are not designed to move Model S out of its driving lane. Do
not rely on steering interventions to avoid side collisions.
Emergency Lane Departure Avoidance
Emergency Lane Departure Avoidance automatically applies steering to avoid a potential collision in situations
where:
• Model S is departing a lane and may collide with a vehicle traveling in the same direction in the adjacent lane
(regardless of the status of the turn signal).
• Model S is departing a lane into an oncoming lane, the turn signal is off, and an oncoming vehicle is detected.
• Model S is departing the road and the turn signal is off (for example, very close to the edge of the road and a
collision may occur).
To turn this feature on or off, touch Controls > Autopilot > Emergency Lane Departure Avoidance.
When Emergency Lane Departure Avoidance applies steering, a chime sounds and the instrument panel displays a
warning and highlights the lane marking in red.
Emergency Lane Departure Avoidance operates when Model S is traveling between 40 and 90 mph (64 and 145
km/h) on a road with clearly visible lane markings, curbs, etc.
WARNING: Emergency Lane Departure Avoidance is not a substitute for attentive driving and sound judgment.
Keep your eyes on the road when driving and never depend on Emergency Lane Departure Avoidance to
prevent a collision. Several factors can reduce or impair performance. Depending on Emergency Lane
Departure Avoidance to prevent a potential collision can result in serious injury or death.
Blind Spot Collision Warning Chime
If you want a chime to sound when a vehicle is in your blind spot and a possible collision is detected, touch Controls
> Autopilot > Blind Spot Collision Warning Chime.
WARNING: Blind Spot Camera does not eliminate the need to drive attentively and manually perform shoulder
checks when changing lanes.
WARNING: Blind Spot Collision Warning Chime cannot detect every collision. It is the driver's responsibility to
remain alert and perform the appropriate shoulder checks when changing lanes.

Limitations and Inaccuracies
Lane Assist features cannot always detect lane markings and you may experience unnecessary or invalid warnings in
these situations:
• Visibility is poor and lane markings are not clearly visible (due to heavy rain, snow, fog, etc.).
• Bright light (such as from oncoming headlights or direct sunlight) is interfering with the view of the camera(s).
• A vehicle in front of Model S is blocking the view of the camera(s).
• The windshield is obstructing the view of the camera(s) (fogged over, dirty, covered by a sticker, etc.).
• Lane markings are excessively worn, have visible previous markings, have been adjusted due to road construction,
or are changing quickly (for example, lanes branching off, crossing over, or merging).
• The road is narrow or winding.
• Objects or landscape features are casting strong shadows on lane markers.
Lane Assist may not provide warnings, or may apply inappropriate warnings, in these situations:
• One or more of the sensors (if equipped) or cameras is damaged, dirty, or obstructed (by mud, ice, or snow, or by
a vehicle bra, excessive paint, or adhesive products such as wraps, stickers, rubber coatings, etc.).
• Weather conditions (heavy rain, snow, fog, or extremely hot or cold temperatures) are interfering with sensor
operation.
• The sensors (if equipped) are affected by other electrical equipment or devices that generate ultrasonic waves.
• An object that is mounted to Model S is interfering with and/or obstructing a sensor (such as a bike rack or a
bumper sticker).
In addition, Lane Assist may not steer Model S away from an adjacent vehicle, or may apply unnecessary or
inappropriate steering, in these situations:
• You are driving Model S on sharp corners or on a curve at a relatively high speed.
• Bright light (such as from oncoming headlights or direct sunlight) is interfering with the view of the camera(s).
• You are drifting into another lane but an object (such as a vehicle) is not present.
• A vehicle in another lane cuts in front of you or drifts into your driving lane.
• Model S is not traveling within the speeds at which the Lane Assist feature is designed to operate.
• One or more of the sensors (if equipped) is damaged, dirty, or obstructed (such as by mud, ice, or snow, or by a
vehicle bra, excessive paint, or adhesive products such as wraps, stickers, rubber coating, etc.).
• Weather conditions (heavy rain, snow, fog, or extremely hot or cold temperatures) are interfering with sensor
operation.
• The sensors (if equipped) are affected by other electrical equipment or devices that generate ultrasonic waves.
• An object mounted to Model S (such as a bike rack or a bumper sticker) is interfering with or obstructing a
sensor.
• Visibility is poor and lane markings are not clearly visible (due to heavy rain, snow, fog, etc.).
• Lane markings are excessively worn, have visible previous markings, have been adjusted due to road construction
or are changing quickly (for example, lanes branching off, crossing over, or merging).
WARNING: The lists above do not represent every possible situation that may interfere with Lane Assist
features. There are many reasons why Lane Assist may not operate as intended. To avoid a collision, stay alert
and always pay attention to the road so you can anticipate the need to take corrective action as early as
possible.
