216

Owners Manual
NOTE: The above intervals are based on typical driving behaviors and scenarios. However, Model 3 should generally
be serviced on an as-needed basis; depending on various circumstances such as driving behavior, usage,
environmental conditions, etc., the above maintenance items may need to be replaced more or less frequently than
specified. Additionally, the above list should not be considered comprehensive and does not include consumable
parts such as windshield wipers, brake pads, low voltage lead-acid battery (if applicable), etc.
NOTE: Damages or failures caused by maintenance or repairs performed by non-Tesla certified technicians are not
covered by the warranty.
Schedule Service
Scheduling a service visit through the mobile app is easy. After touching Schedule Service, select the type of service
needed and follow the directions in the mobile app. Provide as much detail as possible, such as:
• Photos, sound recordings, or videos.
• Date(s), time(s), and time zone when the issue occurred.
• Country of use and location.
• Approximate speed the vehicle was traveling (if applicable).
• Environmental conditions (rain, snow, cold, etc.).
• Road name and type of road (if applicable).
• Quality of lane markings (if applicable).
• Applicable vehicle settings.
• Identifiable symptoms.
Visit https://www.tesla.com/support/service-visits for more information on scheduling service.
Daily Checks
• Check the Battery’s charge level, displayed on the touchscreen or mobile app.
• Check the condition and pressure of each tire (see Tire Care and Maintenance on page 234).
• Check that all exterior lights, horn, turn signals, and wipers and washers are working.
• Check for any unexpected indicator lights or vehicle alerts on the touchscreen.
• Check the operation of the brakes, including the parking brake.
• Check the operation of the seat belts (see Seat Belts on page 54).
• Look for abnormal fluid deposits underneath Model 3 that might indicate a leak. It is normal for a small pool of
water to form (caused by the air conditioning system’s dehumidifying process).
• Look around the exterior of Model 3 and immediately remove any corrosive substances (such as bird droppings,
tree resin, tar spots, dead insects, industrial fallout, etc.) to prevent damage to the paint (see Cleaning on page
243).
Monthly Checks
• Check windshield washer fluid level and top up if necessary (see Topping Up Windshield Washer Fluid on page
248).
• Check that the air conditioning system is operating correctly (see Operating Climate Controls on page 176).
NOTE: In addition to cooling the interior, the air conditioning compressor also cools the Battery. Therefore, in hot
weather, the air conditioning compressor can turn on even if you turned it off. This is normal because the system’s
priority is to cool the Battery to ensure it stays within an optimum temperature range to support longevity and
optimum performance. Also, even when not in use, you may hear Model 3 emit a whining noise or the sound of water
circulating. These sounds are normal and occur when the internal cooling systems turn on to support various vehicle
functions, such as maintaining the low voltage battery and balancing the temperature of the high voltage Battery.
WARNING: Contact Tesla immediately if you notice any significant or sudden drop in fluid levels or uneven tire
wear.

217

Owners Manual

Tire Care and Maintenance
Displaying Tire Pressures
Tire pressures display on the touchscreen in the cards area on the car status display, or by touching Controls >
Service. The pressure of each tire displays in the visualization of your Model 3, in addition to what time your tire
pressures were last measured. You can choose whether you want to display tire pressures using Bar or PSI by
touching Controls > Display > Tire Pressure. The touchscreen also displays your vehicle's recommended cold tire
pressures so you can easily determine how much to inflate your tires.
NOTE: You may need to drive briefly before the visualization displays the tire pressure values.
Maintaining Tire Pressures
Keep tires inflated to the pressures shown on the Tire and Loading Information label, even if it differs from the
pressure printed on the tire itself. The Tire and Loading Information label is located on the center door pillar and is
visible when the driver door is open.
NOTE: If your Model 3 is fitted with Tesla accessory wheels or tires, some information may be different from the
labels on the vehicle. See Accessory Wheels and Tires on page 252.

The Tire Pressure indicator light on the touchscreen alerts you if one or more tires is under- or overinflated.

The Tire Pressure indicator light does not immediately turn off when you adjust tire pressure. After inflating the tire
to the recommended pressure, you must drive over 15 mph (25 km/h) for a short amount of time to activate the Tire
Pressure Monitoring System (TPMS), which turns off the Tire Pressure indicator light.
If the indicator light flashes for one minute whenever you power on Model 3, a fault with the TPMS is detected (see
TPMS Malfunction on page 241).
NOTE: Your vehicle’s tire pressures will drop in cold ambient temperatures. If the TPMS indicator light appears,
inflate the tires before driving. The tires will lose one PSI for every 10° F (6° C) drop in outside temperature. Proper
tire pressures help protect tires from potholes and improve range when properly inflated.

234

Owners Manual
WARNING: Under-inflation is the most common cause of tire failures and can cause a tire to overheat, resulting
in severe tire cracking, tread separation, or blowout, resulting in unexpected loss of vehicle control and
increased risk of injury. Under-inflation also reduces the vehicle's range and tire tread life.
WARNING: Check tire pressures using an accurate pressure gauge when tires are cold. It takes only about one
mile (1.6 km) of driving to warm up 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.
Checking and Adjusting Tire Pressures

Follow these steps when tires are cold and Model 3 has been stationary for over three hours:
1. Refer to the Tire and Loading Information label located on the driver’s center door pillar for the target tire
pressure.
2. Remove the valve cap.
3. Firmly press an accurate tire pressure gauge onto the valve to measure pressure.
4. If required, add or remove air to reach the recommended pressure.
NOTE: You can release air by pressing the metal stem in the center of the valve.
5. Re-check pressure using the accurate tire gauge.
6. Repeat steps 3 and 4 as necessary until the tire pressure is correct.
7. Reinstall the valve cap to prevent dirt from entering. Periodically check the valve for damage and leaks.
Inspecting and Maintaining Tires
Regularly inspect the tread and side walls for any sign of distortion (bulges), foreign objects, cuts or wear.
WARNING: Do not drive Model 3 if a tire is damaged, excessively worn, or inflated to an incorrect pressure.
Check tires regularly for wear, and ensure there are no cuts, bulges or exposure of the ply/cord structure.
Tire Wear

Adequate tread depth is important for proper tire performance. Tires with a tread depth less than 4/32” (3 mm) are
more likely to hydroplane in wet conditions and should not be used. Tires with a tread depth less than 5/32” (4 mm)
do not perform well in snow and slush and should not be used when driving in winter conditions.
Model 3 is originally fitted with tires that have wear indicators molded into the tread pattern. When the tread has
been worn down to 4/32” (3 mm), the indicators start to appear at the surface of the tread pattern, producing the
effect of a continuous band of rubber across the width of the tire. For optimal performance and safety, Tesla
recommends replacing tires before the wear indicators are visible.
To improve vehicle handling characteristics and minimize hydroplaning in wet conditions, put tires with the most
tread on the rear of the car.
Tire Rotation, Balance, and Wheel Alignment

Tesla recommends rotating the tires every 6,250 miles (10,000 km) or if tread depth difference is 2/32 in (1.5 mm) or
greater, whichever comes first.
Tire rotation is an essential part of tire maintenance. It helps maintain an even treadwear pattern which enhances the
tire's overall wear quality, decreases road noise and maximizes tire life.
Unbalanced wheels (sometimes noticeable as vibration through the steering wheel) affect vehicle handling and tire
life. Even with regular use, wheels can get out of balance. Therefore, they should be balanced as required.
If tire wear is uneven (on one side of the tire only) or becomes abnormally excessive, check the wheel alignment. If
the tires need to be serviced, such as rotated or replaced, reset the tire configuration (see Tire Configuration on
page 239) to improve your driving experience.

235

Owners Manual
Punctured Tires

A puncture eventually causes the tire to lose pressure, which is why it is important to check tire pressures frequently.
Permanently repair or replace punctured or damaged tires as soon as possible.
Your tubeless tires may not leak when penetrated, provided the object remains in the tire. If, however, you feel a
sudden vibration or ride disturbance while driving, or you suspect a tire is damaged, immediately reduce your speed.
Drive slowly, while avoiding heavy braking or sharp steering and, when safe to do so, stop the vehicle. Arrange to
have Model 3 transported to a Tesla Service Center, or to a nearby tire repair center.
NOTE: In some cases, you can temporarily repair small tire punctures (under 1/4” (6 mm)) using an optional tire
repair kit available from Tesla. This allows you to slowly drive Model 3 to Tesla or to a nearby tire repair facility.
WARNING: Do not drive with a punctured tire that has not been repaired, even if the puncture has not caused
the tire to deflate. A punctured tire can deflate suddenly at any time.
Flat Spots

If Model 3 is stationary for a long period, tires can form flat spots. When Model 3 is driven, these flat spots cause a
vibration which gradually disappears as the tires warm up and regain their original shape.
To minimize flat spots during storage, inflate tires to the maximum pressure indicated on the tire wall. Then, before
driving, release air to adjust tire pressure to the recommended levels.
Improving Tire Mileage

To improve the mileage you get from your tires, maintain tires at the recommended tire pressures, observe speed
limits and advisory speeds, and avoid:
• Pulling away quickly, or hard acceleration.
• Fast turns and heavy braking.
• Potholes and objects in the road.
• Hitting curbs when parking.
• Contaminating tires with fluids that can cause damage.
Replacing Tires and Wheels
Tires degrade over time due to the effects of ultraviolet light, extreme temperatures, high loads, and environmental
conditions. It is recommended that tires are replaced every six years, or sooner if required, even if tread depth is
above the minimum.
When a tire set becomes worn, replace all four tires at the same time. Choose a Tesla-approved tire which is
designed specifically for your vehicle. Most Tesla-approved tires can be identified with a Tx specification (for
example, T0, T1, T2). Tesla-approved tires are designed to reduce road noise and optimize handling, ride, and range.
Contact Tesla Service for information.
If tires need to be replaced early, for example due to a flat tire, we recommend replacing the tires in pairs unless the
other tires are within 2/32 in (1.5 mm) of tread depth of the new tire. When replacing tires, it is important to match
the brand and model of the older tires. Always place a pair of new tires on the rear if all four tires are the same size.
Always balance the wheel and tire after replacing a tire. Consult with a professional tire retailer and installer for
further guidance. If you replace your tires or install different ones, reset the tire configuration (see Tire Configuration
on page 239). This resets the learned tire settings and improves the driving experience on your new tires.
NOTE: Regardless of the number of tires replaced, a complete set of matching tires is recommended for optimum
performance.
If tires other than those specified are used, ensure that the load and speed ratings marked on the tire (see
Understanding Tire Markings on page 287) equal or exceed those of the original specification.
For the specification of the original wheels and tires installed on Model 3, see Wheels and Tires on page 285.

236

Owners Manual
If you replace a wheel, the TPMS (Tire Pressure Monitoring System) sensors need to be reset to ensure they provide
accurate warnings when tires are under- or over-inflated (see Automatic Reset of TPMS Sensors on page 240 and
Manually Resetting TPMS Sensors on page 240) (see Automatic Reset of TPMS Sensors on page 240).
NOTE: Installing winter tires with aggressive compound and tread design may result in temporarily-reduced
regenerative braking power. However, your vehicle is designed to continuously recalibrate itself, and after changing
tires it will increasingly restore regenerative braking power after some moderate-torque straight-line accelerations.
For most drivers this occurs after a short period of normal driving, but drivers who normally accelerate lightly may
need to use slightly harder accelerations while the recalibration is in progress. Go to Service > Wheel & Tire
Configuration > Tires to select winter tires and quicken this process.
WARNING: For your safety, use only tires and wheels that match the original specification. Tires that do not
match the original specification can affect the operation of the TPMS.
WARNING: Never exceed the speed rating of your vehicle's tires. The speed rating is shown on the sidewall of
your tires (see Understanding Tire Markings on page 287).
Asymmetric Tires

Model 3 tires are asymmetric and must be mounted on the wheel with the correct sidewall facing outward. The
sidewall of the tire is marked with the word OUTSIDE. When new tires are installed, make sure that the tires are
correctly mounted on the wheels.

WARNING: Road holding is seriously impaired if the tires are incorrectly installed on the wheels.
Removing and Installing Aero Covers

If your Model 3 is equipped with aero covers, you must remove them to access the lug nuts.
To remove an aero cover:
1. Grasp the aero cover firmly with both hands.
2. Pull the aero cover toward you to release the retaining clips.

To install an aero cover:
237

Owners Manual
1. Align the aero cover into position so that the notch at the base of the Tesla "T" is aligned with the tire's valve
stem.

2. Push firmly around the perimeter of the aero cover until it fully snaps into place.
For Gemini wheels, press on the perimeter of the cover until it aligns with the wheel surface. Press on the Tesla
“T” in the center until the cap snaps into place. See Parts and Accessories on page 252 for more information.
CAUTION: To prevent the aero cover from falling off, ensure that it is fully secured before driving.

Removing and Installing Lug Nut Covers

If your Model 3 is equipped with lug nut covers, you must remove them to access the lug nuts.
To remove a lug nut cover:
1. Insert the curved part of the lug nut cover tool, if equipped (located in the glovebox in some vehicles, or you can
use a small allen wrench) into the hole at the base of the Tesla "T".
NOTE: The lug nut cover tool can also be purchased at an auto parts store or through online retailers.

2. Maneuver the lug nut cover tool so that it is fully inserted into the hole in the lug nut cover.
3. Twist the lug nut cover tool so that the curved part is touching the middle of the lug nut cover.
238

Owners Manual
4. Firmly pull the lug nut tool away from the wheel until the lug nut cover is released.

To install the lug nut cover:
1. Align the lug nut cover into position.
2. Push firmly on the lug nut cover until it fully snaps into place.
CAUTION: Make sure the lug nut cover is fully secure before driving to prevent it from falling off.

Wheel Configuration

If you are installing new wheels or swapping them for different ones, update your vehicle's wheel configuration by
touching Controls > Service > Wheel & Tire Configuration > Wheels. This allows Model 3 to learn the new wheels
and provide more accurate status updates on your vehicle. Select a wheel from the drop down menu that matches
the new wheels you plan to install on Model 3. Selecting new wheels in the wheel configuration also changes the
wheels that appear on your vehicle's avatar on the touchscreen.
NOTE: Changing your vehicle's wheel configuration can impact range estimates, tire pressure warning levels, and
vehicle visualization.
WARNING: Only use Tesla-approved wheels when installing or swapping wheels. Using non Tesla-approved
wheels can cause serious damage. Tesla is not liable for damage caused by using wheels not approved by
Tesla.
Tire Configuration
After the tires on Model 3 are rotated or replaced, update your vehicle's tire configuration by touching Controls >
Service > Wheel & Tire Configuration > Tires. This allows your vehicle to reset the learned tire settings and improve
your driving experience. This also clears and resets the tread wear alert for the vehicle until you travel 6,250 miles
and low tread depth is detected again.
Ensure you are aware if your vehicle is equipped with winter tires. Winter tires can be identified by a mountain and
snowflake icon on the tires' sidewall. See Winter Tires on page 241 for more information.
NOTE: Changing your vehicle's tire configuration can temporarily impact acceleration and regenerative braking
levels and should only be done after tires have been rotated or replaced.

239

Owners Manual
Tire Pressure Monitoring
Each tire should be checked monthly when cold and inflated to the recommended pressures that are printed on the
Tire and Loading Information label located on the driver’s door pillar (see Maintaining Tire Pressures on page 234). If
your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label,
determine the proper tire inflation pressure for those tires.
As an added safety feature, your vehicle has been equipped with a TPMS that displays a tire pressure telltale (Tire
Pressure Warning) on the touchscreen when one or more of your tires is significantly under- or over-inflated.
Accordingly, when the Tire Pressure indicator light displays on the touchscreen to alert you about tire pressure, stop
and check your tires as soon as possible, and inflate them to the proper pressure (see Maintaining Tire Pressures on
page 234). Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces range efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.
If Model 3 detects a fault with the TPMS, this indicator flashes for one minute whenever you power on
Model 3.

NOTE: Installing accessories that are not approved by Tesla can interfere with the TPMS.
WARNING: The TPMS is not a substitute for proper tire maintenance, including manually checking tire
pressures and regularly inspecting the condition of tires. It is the driver's responsibility to maintain correct tire
pressure, even if under- or over-inflation has not reached the level for the TPMS to trigger the Tire Pressure
Warning on the touchscreen.
Automatic Reset of TPMS Sensors

After replacing one or more wheels (but not after replacing a tire or rotating wheels), the TPMS sensors are reset to
ensure tire pressure warnings are accurate. TPMS sensors reset automatically after driving over 15 mph (25 km/h) for
longer than 10 minutes.
NOTE: After replacing a wheel, false tire pressure warnings may display before you've driven 15 mph (25 km/h) for
longer than 10 minutes.
