Engaging Locking Differentials On Road
WARNING: Your vehicle's turning radius increases when locking differentials are engaged. It is your responsibility to be
aware of your surroundings and drive carefully.
Engaging locking differentials while driving on roads is intended for specific situations where you temporarily need extra grip
on loose or uneven terrain, such as getting un-stuck from a snow bank. Do not engage locking differentials unless it is needed
for the road conditions. Navigate to Controls > Dynamics > Engage Rear Locking Differential. When enabled, Slippery Surface
also enables (see Slippery Surfaces on page 1241). Engage Rear Locking Differential should not be used for regular driving on
slick surfaces.
When you engage locking differentials while driving on roads, your speed is limited to 35 mph (56 km/h). The stability control
icon may appear momentarily while the locking differentials disengage (see Vehicle Status on page 1121).
NOTE: This option is not available on Tri-Motor (Cyberbeast) vehicles.

Engaging Locking Differentials Off Road
Before you engage locking differentials, consider your driving situation (such as the terrain, weather, etc.). The rear locking
differentials are ideal for off-roading uphill or on level surfaces. Front locking differentials are typically used when you need
more traction at the front of the vehicle, like rock crawling. To engage:
1. Access the Off-Road app.
2. Select the locking differentials you want to enable.
For dual motor variants:
◦ All On
◦ Rear Only
◦ Off
For Tri-Motor (Cyberbeast) variants:
◦ Front Only

Or touch the associated locking differential icon in the vehicle status area and select which locking differential(s) you want to
engage:
Gray: Locking differential is disengaged.
Blinking orange: Locking differential is engaging or disengaging.

Solid orange: Locking differential is engaged.

Orange question mark (?): Unknown locker position.

Red exclamation point (!): System fault or locking differential unavailable (see Troubleshooting on page 1257).

You may need to drive a short distance to engage once enabled.
Once the locking differentials are fully engaged, the vehicle may slightly rock side to side when turning at low speeds. This is
normal behavior when the touchscreen indicates a fully engaged locker (solid orange icon).
The locking differentials may cancel or delay engaging in various cases. If the locking differentials are unable to engage, a
chime sounds and a message displays on the touchscreen. See Troubleshooting on page 1257 for more information.
WARNING: Driving with locked differentials may reduce vehicle responsiveness to steering. Always monitor your
vehicle's behavior and the surroundings. Failure to do so may result in damage or serious injury.

Disengaging Locking Differentials
To disengage, touch the differential icon on the touchscreen and select Off. You may need to drive a short distance to
disengage. The locking differentials also automatically attempt to disengage whenever the vehicle shifts out of Drive, or when
a different drive mode is selected.
When you disengage the locking differentials, the icon may blink orange before disappearing from the touchscreen. Ensure
the locking differentials are disengaged before you drive on paved roads or at speeds higher than 35 mph (56 km/h). Check
the vehicle wheels are not skipping when turning.

Troubleshooting
Off-Road Troubleshooting
You may need to increase traction while off-roading (such as for getting unstuck or overcoming an obstacle). Follow these
general guidelines to provide more traction to CybertruckModel SModel XModel 3Model Y:
1. Engage Overland (see Overland on page 1252 for more information).
2. Adjust the suspension height. Raise the suspension until the vehicle is no longer obstructed. Avoid lowering the
suspension to prevent damage (see Suspension on page 1242).
3. Customize Terrain based on the current surface conditions. For high traction terrains, select Rock. For looser terrains,
select Sand.
4. Engage the front and/or rear locking differentials (see Locking Differentials on page 1255).
5. For softer terrain or steep inclines, engage Trail Assist for a steady progression through complex terrain (see Trail Assist on
page 1255).
If you still need more traction, perform the following:
1. Decrease tire pressure to 36 PSI. This increases tire contact with the surface, which can help provide more traction.
CAUTION: The TPMS warning thresholds may be lowered to accommodate different off-road needs. Do not rely
solely on the TPMS warning indicator when in an Off-Road mode or setting, as these thresholds do not comply with
Federal TPMS standards. It is your responsibility to ensure tires are adequately inflated at all times and are inflated
back to normal levels before regular driving on roads.
2. Use traction aids, such as traction boards.
3. Tow your vehicle. See Instructions for Transporters on page 1446 for more information on towing
CybertruckModel SModel XModel 3Model Y.

Limitations and Warnings
Off-road driving depends on the performance of the air suspension system, brakes, power steering, and other vehicle
systems. If there is a condition affecting the performance of any dependent system, a message displays on the touchscreen
and off-road driving modes are unavailable.
WARNING: Before driving off road, carefully survey the terrain and be aware of the weather forecast and other
environmental conditions. Exercise extreme caution when approaching steep ascents and descents. While driving off
road, always be aware of your surroundings and survey the terrain as necessary. Tesla is not liable for any damage to
CybertruckModel SModel XModel 3Model Y resulting from off-road driving.

1258

Owner's Manual

Off-Roading
WARNING: Never depend on the driving visualization to show you obstacles in front of, behind, or to the sides of
CybertruckModel SModel XModel 3Model Y. Always use caution while driving off road and perform visual checks when
necessary. The visualization relies on the cameras mounted on CybertruckModel SModel XModel 3Model Y (see
Cameras on page 1138). External factors (such as a dirty or obscured lens) may affect the performance of a camera, and
the cameras may not detect objects or barriers that can potentially cause damage or injury.
WARNING: Visibility may be limited by sharp crests and uneven terrain. Always check what is at the top of a hill and over
the crest before driving over it, and be aware of steep descents or other obstacles.
WARNING: Before approaching an obstacle, ensure that CybertruckModel SModel XModel 3Model Y has enough
ground clearance to clear it. If the bottom of CybertruckModel SModel XModel 3Model Y is contacting the ground even
with the ride height at the highest setting, reduce your speed or avoid the obstacle altogether.
WARNING: Exercise extra caution when the terrain surface is wet, sandy, or slippery. Loose gravel, sand, and other
environmental conditions may affect the performance of Off-Road Modes.
WARNING: Before driving off road, make sure that loose items in the cabin are stowed or secured and ensure that the
cargo bed is free of cargo, or that cargo is tightly secured.

Towing
Towing a Trailer
NOTE: You cannot enable Off-Road Modes and Trailer Mode at the same time.
NOTE: If the towing capacity on the hitch label conflicts with the information provided in this owner's manual, this owner's
manual takes precedence.

Towing Guidelines
Towing a trailer puts additional load on the motors, drive train, brakes, tires, and suspension and significantly decreases range.
If you tow a trailer, follow these general guidelines:
• Reduce your driving speed and avoid sudden maneuvers. Keep in mind that when towing a trailer, steering, stability, turning
radius, stopping distances, and braking performance are different when compared to driving without a trailer.
• Increase your following distance by maintaining at least twice the typical distance from the vehicle ahead. This helps avoid
situations that require heavy braking. Sudden braking may result in skidding or jack-knifing, and loss of control.
• Avoid sharp turns. Sharp turns can cause the trailer to contact CybertruckModel SModel XModel 3Model Y and cause
damage. Make wider turns to prevent the trailer from hitting curbs, road signs, trees, or other objects.
• Periodically check the trailer lights and turn signals to confirm that bulbs are still working (see Trailer Light Test on page
1263). When towing a trailer, the turn signal arrows on the touchscreen flash as normal, even if the bulbs on the trailer are
burnt out.
• Periodically confirm the cargo is secure.
• Periodically confirm the trailer brakes are working (see Trailer Brakes on page 1262).
• Avoid parking on a grade (see Parking with a Trailer on page 1265).
• Regularly confirm that all towing components are secured.

Before Towing a Trailer
Before towing a trailer, you must do the following:
1. Review all regulations and legal requirements in your state/region that apply to towing a trailer. Failure to comply with
regulations can compromise your safety.
2. Inflate tires to the cold tire inflation pressure specified in Tire Pressures when Towing on page 1261.
3. Set the suspension height to match the trailer height. Tesla recommends Low (Controls > Suspension > Low). You must
choose a ball mount suitable for your towing needs. See Ball Mount Specifications on page 1266 for more information.
4. Adjust all mirrors to provide a clear rearward view without a significant blind spot.
NOTE: Use towing mirrors for larger trailers.
5. Confirm the trailer load is evenly distributed such that the trailer tongue weight is approximately 10% of the total trailer
weight, without exceeding the maximum tongue weights provided in Towing Capacity on page 1261.
6. Engage Trailer Mode (see Trailer Mode on page 1262).
7. Calibrate the trailer brakes (see Trailer Brakes on page 1262).
Then, confirm the following:
1. CybertruckModel SModel XModel 3Model Y rests horizontally with the trailer attached. If the vehicle is tipped up at the
front, and down at the rear, check that you are not exceeding the maximum towing capacity and tongue weights provided in
Towing Capacity on page 1261.
2. All trailer hitch parts and attachments, safety chains, and electrical connectors are in good condition and properly
connected. If any problems are apparent, do not tow the trailer.
3. Trailer lights (brake lights, turn signal lights, marker lights, etc.) are working properly.
4. The trailer tongue is securely connected to the hitch ball.

1260

Owner's Manual

Towing
5. Safety chains are properly connected between the trailer and the vehicle. Cross the safety chains under the tongue of the
trailer to help prevent the tongue from contacting the road if it separates from the hitch. Leave enough slack in the safety
chains to allow for turns and ensure that the chains can never drag on the ground.
6. Wheel chocks are available and easy to access.
7. All cargo is secured.
NOTE: For general information about trailer safety provided by the National Highway Traffic Safety Administration, go to
https://one.nhtsa.gov/cars/problems/equipment/towing/index.htm.
WARNING: The trailer tongue weight must be approximately 10% of the total trailer weight without exceeding the
maximum tongue weights provided in Towing Capacity on page 1261. Loads that are balanced over the wheels or heavier
in the rear can cause trailer sway, resulting in loss of vehicle control.
WARNING: Always ensure that cargo is secured in the trailer and will not shift. Dynamic load shifts can cause loss of
vehicle control, resulting in serious injury or death.

Towing Capacity
The total trailer weight (including all cargo and additional equipment), and the trailer tongue weight, must never exceed the
following:
Wheel Size

Maximum Towing Capacity

Maximum Tongue Weight*

20" x 9J

11,000 lb (4,990 kg)

1,100 lb (499 kg)

*The tongue weight is the downward force that the weight of the trailer exerts on the hitch. It must not exceed 10% of the
maximum towing capacity. Carrying a significant amount of equipment, passengers, or cargo in the tow vehicle can reduce the
tongue weight it can handle, which also reduces the maximum towing capacity. Maximum towing capacity is calculated
assuming the GVWR (Gross Vehicle Weight Rating) is not exceeded. For GVWR, see Vehicle Loading on page 1436).
CAUTION: Tesla assumes no responsibility for damage or injuries resulting from towing a trailer, for any errors or
omissions in the instructions accompanying towing equipment, or for your failure to follow the proper instructions.
Damage caused by towing a trailer is not covered by the warranty.
WARNING: Do not overload the vehicle or trailer. Doing so can cause poor performance, vehicle damage and loss of
vehicle control, resulting in serious injury.
WARNING: Do not use the trailer hitch to tow/transport CybertruckModel SModel XModel 3Model Y.
WARNING: Never operate a trailer with a negative tongue weight, where the trailer tongue pulls upward on the trailer
hitch. Negative tongue weights can significantly increase the risk of trailer sway or loss of stability.

Tire Pressures when Towing
When towing a trailer, tire pressures must be adjusted to accommodate the additional load. Keep tires inflated to the pressures
shown below (these pressures override the pressures that are provided on the Tire and Loading information label – see Vehicle
Loading on page 1436):
Tires

Cold Tire Inflation Pressure

20" All Season

50 psi

20" All Terrain

65 psi

WARNING: Check tire pressures using an accurate pressure gauge when tires are cold (see Tire Pressures on page
1401). Driving one mile (1.6 km) warms the tires sufficiently to affect tire pressures. Parking the vehicle in direct sunlight
or in hot weather can also affect tire pressures. If you must check warm tires, expect increased pressures. Do not let air
out of warm tires in an attempt to match recommended cold tire pressures. A hot tire at or below the recommended cold
tire inflation pressure is dangerously under-inflated.
WARNING: Never attempt to tow a trailer when a tire is faulty or has been inflated using a tire repair kit. A temporarily
repaired tire is not designed to sustain the towing load. Towing using a faulty or temporarily repaired tire can result in
tire failure and loss of vehicle stability.

CybertruckModel SModel XModel 3Model Y detects a faulty electrical connection for the trailer lights. Some,
or all, trailer lights may not be functioning. Pull over as soon as safety permits and inspect the trailer lights for
faulty cabling or connections. If the issue is resolved and the red icon persists, manually turn Trailer Mode off
and on again.

Some Autopilot features, and any feature that requires the use of the rear camera, may be unavailable when Trailer Mode is
enabled. In addition, some features may operate differently. For example:
• Autosteer (if equipped) is unavailable. Therefore, for Traffic-Aware Cruise Control availability, touch Controls > Autopilot >
Autopilot Activation > Double Click. This allows you to engage Traffic-Aware Cruise Control with a single click of the right
scroll button on the steering wheelsteering yoke (or steering wheel).
• Traffic-Aware Cruise Control increases the following distance from the car in front of you.
• The air suspension system will not make speed-based adjustments from Medium to Low and does not automatically raise
ride height based on saved locations.
• Side collision warnings are active but automatic steering interventions are disabled.
• The braking force provided by Automatic Emergency Braking (see Collision Avoidance Assist on page 645) is significantly
limited.
NOTE: Trailer brakes are only available when Trailer Mode is engaged.
WARNING: Do not rely on CybertruckModel SModel XModel 3Model Y to automatically detect a trailer in all cases.
Always check that Trailer Mode is engaged before towing a trailer.
WARNING: Remaining in Trailer Mode will help ensure CybertruckModel SModel XModel 3Model Y remains stable in
adverse conditions while towing. Do not exit Trailer Mode while towing a trailer. Exiting Trailer Mode could result in loss
of vehicle stability.

Trailer Alarm

When enabled, Cybertruck sounds an alarm if the vehicle detects the trailer is being unplugged while Trailer Mode is active
and the vehicle is locked.

Trailer Brakes
CybertruckModel SModel XModel 3Model Y is equipped with a trailer brake controller which automatically applies the trailer
brakes when you decelerate. To update your trailer brake preferences, navigate to Controls > Towing & Hauling where you can:
1262

Owner's Manual

Towing
• Enable/disable Trailer Mode on page 1262.
• Customize Trailer Brake Gain on page 1263.
NOTE: Tesla recommends always enabling the trailer brakes, otherwise stopping distance may be increased. To disable the
trailer brakes, first disable Trailer Mode or set the Trailer Brake Gain to 0.
• Choose how to manually apply the trailer brakes (either with the touchscreen or right scroll button). The trailer brake
activation button is unaffected.
• Adjust Trailer Brake Boost on page 1263.
• Toggle Adaptive Regenerative Braking on page 1263.
• Perform the Trailer Light Test on page 1263.
You can also set up a shortcut for Towing & Hauling by adding it to your vehicle "Cards" area, near the bottom of the
touchscreen.
Trailer Brake Gain
The Trailer Brake Gain slider is a scale between 0 and 10 that calibrates the degree of trailer braking applied when you press
the brake pedal normally. 0 applies no trailer brakes, whereas 10 applies the full trailer brakes.
Set this up each time you connect a trailer to ensure your trailer brakes do not lock up:
1. Ensure the trailer is securely attached to the CybertruckModel SModel XModel 3Model Y hitch assembly.
2. Drive CybertruckModel SModel XModel 3Model Y in a safe, open area at low speeds (10-15mph or 15-25 km/h).
3. Use the right scroll button on the steering wheelsteering yoke (or steering wheel) or Trailer Brake Activation (set your
preference in Towing & Hauling) to apply the trailer brakes while moving. Adjust the Trailer Brake Gain as needed to ensure
the trailer brakes do not lock up when they are applied. If the wheels do lock up, decrease the amount of gain slightly and
repeat this process.
The ideal Trailer Brake Gain varies depending on your trailer load, number of axles, and surface conditions. You must adjust as
needed if conditions change.
Trailer Brake Boost
Tesla recommends initially setting your Trailer Brake Boost to Low. Once Trailer Brake Gain is calibrated, adjust based on your
preferences by driving around in a safe, open area and applying the brakes as you would in normal traffic. Increasing will make
your brakes react more quickly, although the braking feels more harsh to passengers.
Adaptive Regenerative Braking
At the start of every drive, CybertruckModel SModel XModel 3Model Y estimates the load to determine the proper level of
regenerative braking. Regenerative braking will start at the standard level and increase as the vehicle learns your trailer/cargo
weight. This weight estimation works best when driving in a straight line on a flat, smooth surface.
NOTE: Adaptive regenerative braking does not engage the trailer brakes. In order to engage the trailer brakes, you must press
the brake pedal or enable trailer brakes on the touchscreen.
WARNING: It is your responsibility to determine when to enable Adaptive Regenerative Braking. Always drive safely and
avoid situations that could require heavy braking.
WARNING: Towing increases your stopping distance. When towing, increase your following distance and avoid
situations that could potentially cause heavy braking. Failure to do so can result in a collision.
WARNING: Observe all regulations and legal requirements in your regional and national jurisdictions that apply
specifically to trailer towing and brake requirements. Many regions require a breakaway switch, located on the tongue of
the trailer, to activate the trailer brakes if the trailer separates from the vehicle. Failure to comply with regulations can
compromise your safety.
Trailer Light Test
Before towing, and periodically during towing, use Trailer Light Test to confirm the trailer lights are working as expected.
WARNING: Do not tow a trailer if the trailer lights or trailer brakes are not working properly.
Owner's Manual

Towing
Trailer Brake Controller Limitations
WARNING: It is your responsibility to understand your towing needs, proper towing procedures, trailer brakes (such as
their use and limitations), and the risks and limitations of towing. Do not tow with CybertruckModel SModel XModel
3Model Y if you do not have towing knowledge and experience; doing so may result in damage, injury or death. Damage
as a result of improper towing is not covered by the warranty.
Keep in mind the following brake controller limitations:
• Properly maintain and use trailer brakes as intended to prevent damage.
• The trailer brake controller and auxiliary output is 12V.
• Abusive or extensively long manual activations of the trailer brake controller may cause overheating with some trailer brake
loads.
• Maximum power draw - The onboard trailer controller is designed to support most trailer power applications. The power
allocations are:
Standard trailer brakes (when braking power is derived from brake
output, e.g. non-EOH Electric Drum brakes)

Lights: Max. 220 Watts total for all light
outputs combined.
Auxiliary power (AUX 12V+ Charging): Max.
270 Watts (20 Amps).
Trailer brakes: Max. 331 Watts

Electric over Hydraulic trailer brakes (braking power is derived from
auxiliary power output, e.g. EOH, Hydraulic disk brakes, see Electric
Over Hydraulic (EOH) Brakes on page 1264)

Lights: Max. 220 Watts total for all light
outputs combined.
Auxiliary power (AUX 12V+ Charging): Max.
405 Watts (30 Amps).
Trailer brakes: Max. 48 Watts (Current draw
must be less than 3 Amps).

CybertruckModel SModel XModel 3Model Y switches to the standard brakes if a 3A or higher load on the trailer brake
connections is detected.

Electric Over Hydraulic (EOH) Brakes
CybertruckModel SModel XModel 3Model Y supports standard electric brakes and Electric over Hydraulic (EOH) brakes. If
using EOH brakes, Tesla recommends connecting a battery in parallel with the auxiliary power output to the EOH unit.
The auxiliary output is capable of supplying up to 30 Amps when supporting an EOH trailer brake unit. You are responsible for
understanding the power needs of your EOH trailer brake unit. Using an EOH trailer brake controller that draws more than 30
Amps may result in a loss of power to the trailer brakes while braking.
The usage of only an EOH unit with the auxilary power port is supported for maximum braking availability. A battery in parallel
is recommended. The battery must be in good health and is expected to already be present in most states per DOT
regulations.
CAUTION: Tesla does not recommend using EOH trailer brakes simultaneously with other auxiliary power loads. Doing
so could lead to complications or loss of power to the EOH trailer brakes unit.

Towing
Parking with a Trailer

Whenever possible, avoid parking on a grade. However, if parking on a grade is absolutely necessary, place wheel chocks
under the trailer wheels:
1. One person presses and holds the brake pedal.
2. A second person places the wheel chocks under the wheels on the downgrade side of the trailer's tires.
3. When the chocks are in place, slowly release the brake pedal and ensure the chocks hold the weight of the vehicle and
trailer.
NOTE: When testing chocks, ensure that Vehicle Hold (see Vehicle Hold on page 1239) is engaged. If Vehicle Hold is
braking CybertruckModel SModel XModel 3Model Y, the associated indicator light appears on the touchscreen. To
disengage Vehicle Hold, press and release the brake pedal.
4. Place the vehicle in Park.
WARNING: If parking on a grade is necessary, ensure that all trailer wheels have been securely chocked. Failure to do so
can result in serious damage, injury, or death.

Trailer Sway Mitigation
When trailer sway is detected, your vehicle's electronic stability control system attempts to apply the appropriate amount of
braking to minimize trailer sway. The touchscreen briefly displays the traction control system indicator. Manually applying the
brakes (via right scroll button on the steering wheelsteering yoke (or steering wheel) or the Trailer Brake setting) when the
system is actively braking to mitigate trailer sway does not cancel this automatic braking. However, it is still your responsibility
to drive carefully and brake when needed, taking into consideration possible trailer sway.

Accessing the Trailer Hitch Assembly
The CybertruckModel SModel XModel 3Model Y trailer hitch assembly is located behind the rear fascia of the vehicle, under
the tailgate. Your vehicle is not equipped with a ball mount, which must be purchased separately based on your towing needs.

Owner's Manual

1265

Towing
The trailer hitch cover is attached to the body of the vehicle with three turn clips. Use a flat trim tool or non-marring
screwdriver to partially turn and unlock the clips, then remove the trailer hitch cover and place it in a secure, dry place. Once
removed, you can see where the ball mount can be installed.

When not actively towing, keep the cover installed to prevent dirt and debris from entering.
NOTE: The maximum permissible rear overhang for the coupling point is 49 in (1.25 m), measuring from the center of the rear
tire toward the hitch receiver.
NOTE: Always attach safety chains when towing. See your trailer Owner's Manual for more information.

Ball Mount Specifications
A ball mount must be purchased separately based on your towing needs. The Cybertruck hitch receiver supports a 2 in (5 cm)
ball mount. Follow the ball mount manufacturer's instructions for more information.

NOTE: Refer to the manufacturer's instructions to properly maintain the ball mount.

Electrical Connections
CybertruckModel SModel XModel 3Model Y is equipped with a combination electrical outlet, located near the hitch assembly,
that supports two types of commonly-used trailer plugs without needing an adapter:
• 7-PIN - SAE J2863 - for heavier trailer loads requiring their own braking system.
• 4-PIN - SAE J1239 - for light trailer loads requiring lights only.

1266

Owner's Manual

Towing
Regulations require that all trailers, at a minimum, are equipped with taillights and turn signals. These are provided on the 4pin connector, which is adequate when pulling a light load. For heavier loads, the trailer must also be equipped with brakes,
available on the 7-pin connector.
Plugging a trailer's wiring into either electrical outlet automatically engages Trailer Mode (see Trailer Mode on page 1262).

Loss of trailer lights when towing may be the result of a fault in the trailer wiring or excessive power consumption by the lights
connected to the trailer output(s). When this occurs, the touchscreen displays a red Trailer Mode icon. Fix any issues with the
wiring and/or reduce the number of lights connected to the trailer output(s), then turn Trailer Mode off and on to try again.
CAUTION: Always ensure that the trailer's electrical cable does not contact or drag on the ground and there is enough
slack in the cable to allow for turns.
WARNING: Before towing, it is the driver's responsibility to ensure that all electrical connections are working, all trailer
lights are operating as expected, and the braking system is fully functioning. CybertruckModel SModel XModel 3Model
Y does not detect faulty electrical connections. You must perform manual checks. Failure to do so can result in property
damage, personal injury, or death.
WARNING: Use only the electrical connection designed by Tesla. Do not attempt to directly splice or attempt to connect
trailer electrical wiring using any other method. Doing so can damage the vehicle electrical system and cause
malfunctions.

Impact on Range
Towing a trailer and carrying accessories increases vehicle weight and drag. As a result, driving range can decrease
significantly. Although Trip Planner attempts to adjust estimates based on Trailer Mode, actual energy consumption may vary.
Plan trip length and charging destinations accordingly.

Carrying Accessories and Crossbars
WARNING: Tesla assumes no responsibility for damage or injuries resulting from installing and using a carrier or
crossbars, for any omissions in the instructions accompanying a carrier or crossbar, or for your failure to follow the
instructions. Damage caused by using a carrier or crossbars is not covered by the warranty.

Carrying Accessories
CAUTION: The hitch assembly is designed to support vertical loads up to 160 lb (72 kg). Exceeding this maximum
weight can cause damage.
The hitch receiver is designed to support vertical loads up to 160 lb (72 kg). When carrying bicycles, skis, or other items on
the Cybertruck's hitch, always check to ensure that the maximum weight is not exceeded. When the carrier weighs 40 lbs (18
kg), the weigh threshold is sufficient for carrying two bicycles weighing approximately 60 lb (27 kg) each, or four items
weighing approximately 30 lbs (14 kg) each.
CAUTION: An accessory carrier attached to the rear of CybertruckModel SModel XModel 3Model Y may obscure your
view from the rear view mirror and the rear camera.
Follow the instructions provided with your accessory carrier to install onto CybertruckModel SModel XModel 3Model Y.
Observe all regulations and legal requirements in your state/region that apply to carrying accessories.
CybertruckModel SModel XModel 3Model Y includes the wiring necessary for using an accessory carrier equipped with lights
(see Electrical Connections on page 1266). CybertruckModel SModel XModel 3Model Y also includes Trailer Mode software
(see Trailer Mode on page 1262).
When you connect an accessory carrier's wiring harness, CybertruckModel SModel XModel 3Model Y detects
a connection for trailer lights and displays this indicator on the touchscreen to indicate that Trailer Mode is
disabled.

When carrying accessories, periodically confirm that the accessory carrier and its cargo remain secure at all times, and if
applicable, that the lights on the accessory carrier are working.
