recommends and supports only Tesla-approved products (see Parts and Accessories on page 795). The accessory products
available for your vehicle may vary based on market region. Before attempting to install a non Tesla-approved carrier, review
the product information to ensure compatibility.
NOTE: When not in use, the ball mount should be removed and stored in a dry location to prevent dust and corrosion. Keep the
dust cover over the hitch housing to prevent dirt and debris from entering (see Attaching and Removing the Ball Mount on
page 530).
NOTE: Tesla assumes no responsibility for damage or injuries resulting from installing and using an accessory carrier, for any
omissions in the instructions accompanying an accessory carrier, or for your failure to follow the instructions. Damage caused
by using an accessory carrier is not covered by the warranty.
Carrying Accessories

The hitch receiver is designed to support vertical loads up to 160 lbs (72 kg). When carrying bicycles, skis, or other items on
the CybertruckModel SModel XModel 3Model Y hitch, always check to ensure that the maximum weight is not exceeded.
When calculating weight, remember to include the weight of the accessory carrier. For example, assuming the carrier weighs
40 lbs (18 kg), the weight threshold is sufficient for carrying two bicycles weighing approximately 60 lbs (27 kg) each, or four
items weighing approximately 30 lbs (14 kg) each.
NOTE: Consult the product details of your accessory carrier for more information, such as additional weight or load limits.
Damage caused by non Tesla-approved accessories is not covered by the warranty.
CAUTION: Exceeding the maximum weight the CybertruckModel SModel XModel 3Model Y hitch is designed to support
(as previously described) can cause significant damage.
CAUTION: Do not attempt to install an accessory carrier on CybertruckModel SModel XModel 3Model Y that is not
equipped with the tow package. Doing so can cause significant damage.
Trailer Towing
The maximum trailer weight (including all cargo and additional equipment), and the trailer tongue weight depend on the
number of occupants in your vehicle and the tires being used. The maximum towing capacity and trailer tongue weight must
never exceed the following:

*Applicable only to vehicles with seven seating positions.
** You must operate within the speed limitations of your trailer and tires, and only drive at speeds appropriate for the load you
are towing, the weather, road and traffic conditions, and your level of towing experience. Always obey posted speed limits and
local regulations regarding speed.
NOTE: In Canada, towing is limited to 55 mph (89 km/h).
For trailers with a combined loading of more than 1650 lbs (750 kg), Tesla recommends using a separate braking system with
an independent controller (see Trailer Brakes on page 528). Carefully follow the instructions provided by the trailer brake
manufacturer to ensure that trailer brakes are properly installed, adjusted, and maintained.
The tongue weight is the downward force that the weight of the trailer exerts on the hitch. This must not exceed 10% of the
maximum trailer weight. Carrying a significant amount of equipment, passengers, or cargo in the tow vehicle can reduce the
towing capacity it can handle, which also reduces the tongue weight. Maximum towing capacity is calculated assuming the
GVWR (Gross Vehicle Weight Rating) is not exceeded (see Specifications on page 831).
NOTE: If the information on the hitch label conflicts with the information provided in this Owner's Manual, this Owner's Manual
takes precedence.
CAUTION: You should only use CybertruckModel SModel XModel 3Model Y to tow if you have experience and
knowledge of how towing affects the vehicle and are able to safely load, secure, and maneuver the vehicle and cargo.
Tesla's instructions are not all-inclusive of the knowledge and skills necessary for safe towing. 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 transport CybertruckModel SModel XModel 3Model Y (see Instructions for
Transporters on page 913).
Tire Pressures when Towing
When towing a trailer, tire pressures must be adjusted to accommodate the additional load. 19", 20", and 21" tires are
acceptable to use for towing. Keep tires inflated to the pressures shown below (if different, these pressures override the
pressures that are provided on the Tire and Loading Information Label (see Vehicle Loading on page 839)).
Front Tires

275/35R21

42 psi (290 kPa)

CAUTION: Do not use CybertruckModel SModel XModel 3Model Y for towing if equipped with tires that are not listed
previously.
WARNING: Check tire pressures using an accurate pressure gauge when tires are cold. 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 may be
dangerously under-inflated.
WARNING: Never attempt to tow a trailer when a CybertruckModel SModel XModel 3Model Y tire is faulty or has been
temporarily repaired (for example, 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.
Before Towing a Trailer
Before towing a trailer, you must do the following:
• Inflate tires to the cold tire inflation pressure specified in Tire Pressures when Towing on page 526.
• Observe all regulations and legal requirements that apply to trailer towing. Failure to comply with regulations can
compromise your safety.
• Adjust side mirrors to provide a clear rear view without a significant blind spot.

526

Owner's Manual

Owners Manual
• Engage Trailer Mode (see Trailer Mode on page 527).
Confirm the following:
• 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 loads provided in
Trailer Towing on page 525.
• Trailer lights (brake lights, turn signal lights, and marker lights) are working properly.
• The trailer tongue is securely connected to the hitch ball.
• Safety chains are properly connected between the trailer and the tow 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 do not drag on the ground.
• All trailer hitch parts and attachments, safety chains, and electrical connectors are in good condition and are properly
connected. If any problems are apparent, do not tow the trailer.
• All cargo is secured.
• Wheel chocks are available.
• The trailer load is evenly distributed such that the trailer tongue weight is approximately 4-10% of the total trailer weight,
without exceeding the maximum tongue weights provided in Trailer Towing on page 525.
CAUTION: Loads that are balanced over the trailer 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.
Towing Guidelines
CybertruckModel SModel XModel 3Model Y is designed primarily as a passenger-carrying vehicle. Towing a trailer puts
additional load on the motor(s), drive train, brakes, tires, and suspension and significantly decreases range. If you decide to
tow a trailer, proceed with caution and follow these general guidelines:
• Reduce your driving speed and avoid sudden maneuvers. When towing a trailer, steering, stability, turning radius, stopping
distance and braking performance are different when compared to driving without a trailer.
• Increase your following distance by maintaining at least twice the distance from the vehicle ahead. This helps to 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 the vehicle and cause damage. Keep in mind that the trailer
wheels are closer to the inside of the turn than the vehicle’s wheels. Therefore, 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 the bulbs are still working. When towing a trailer, the
turn signal arrows on the touchscreen flash as normal, even if the bulbs on the trailer are burned out.
• Periodically confirm the cargo is secure.
• Regularly confirm that all towing components are securely tightened.
WARNING: Towing requires you to increase 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 jurisdiction that apply specifically to trailer towing.
Failure to comply with regulations can compromise your safety.
Trailer Mode
Trailer Mode must always be active when towing a trailer. When you connect a trailer’s electrical connection while the vehicle
is in Park, CybertruckModel SModel XModel 3Model Y automatically engages Trailer Mode. When you disconnect the trailer’s
electrical connection, Trailer Mode does not automatically disengage. To manually engage or disengage Trailer Mode, touch
Controls > Pedals & Steering > Trailer Mode on the touchscreen. One of the following indicators displays:

It is likely that a carrying accessory has been connected.

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 issues are resolved and the red icon still persists, disable and re-enable
Trailer Mode once more.

Some Autopilot features, as well as rear parking sensor functionality, may not be available when Trailer Mode is enabled. In
addition, these features operate differently:
• Traffic-Aware Cruise Control increases the following distance from the vehicle in front of you.
• 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 640) may be limited.
Therefore, stopping distance may increase.
WARNING: Do not rely on CybertruckModel SModel XModel 3Model Y to detect the trailer and automatically engage
Trailer Mode. Always check to ensure Trailer Mode is engaged before towing a trailer.
WARNING: Under no circumstances should you exit Trailer Mode when towing a trailer. Doing so can cause serious
injury.
Trailer Brakes
When towing a loaded trailer that weighs more than 1650 lbs (750 kg), Tesla recommends that the trailer be equipped with its
own brake system adequate for the weight of the trailer. Ensure compliance with local regulations. A brake controller must be
purchased separately, and the required 4-pin pigtail connector can be ordered from Tesla Service.
Follow these steps to connect a brake controller:
1. Connect the wiring on the brake controller to the appropriate locations on the 4-pin pigtail connector.

2. Remove the cover located under the dashboard in the driver’s side footwell.

528

Owner's Manual

Owners Manual

3. Peel back the carpet to expose the vehicle's 4-pin connector on the wiring harness.

4. Connect the pigtail connector to the vehicle wiring connector.
WARNING: Towing increases your stopping distance, even when the trailer is equipped with its own braking system.
When towing, increase your following distance and avoid situations that could potentially cause heavy braking. Failure to
do so can cause 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 in the event that the trailer separates from the vehicle. Failure to comply with
regulations can compromise your safety.
WARNING: Follow the instructions provided by the trailer brake manufacturer to ensure that trailer brakes are properly
installed, adjusted, and maintained. Tesla is not responsible for damages caused by incorrect installation of trailer
braking systems.

Owners Manual
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. Consider having someone help you with these steps:
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 vehicle's tires.
3. When the chocks are in place, 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 491) is not engaged. If Vehicle Hold is
braking CybertruckModel SModel XModel 3Model Y, the Vehicle Hold indicator light displays 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, always ensure that all trailer wheels have been securely chocked. Failure to
do so can result in serious damage or injury.
Trailer Sway Mitigation
When trailer sway is detected, the 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. Pressing the brake pedal when
the system is actively braking to mitigate trailer sway does not cancel this automatic braking.
Attaching and Removing the Ball Mount
The CybertruckModel SModel XModel 3Model Y towing package does not include a ball mount. You must purchase a ball
mount suitable for the type of trailer you are towing. The CybertruckModel SModel XModel 3Model Y hitch receiver supports
a ball mount with a length of up to 8.5” (22 cm) and a rise of up to 0.75” (2 cm). Do not use any type of drop ball mount that
does not meet these requirements.

To attach a ball mount:
1. Use a thin object, such as a butter knife or flat blade screwdriver, to pry around the edges of tow hitch cover and release
the 15 clips that secure the cover to the rear fascia. Store the dust cover in a secure location.

Towing and Accessories
The towing package allows you to tow a trailer with your Model X. It also allows you to carry skis, snowboards, bicycles, etc.
by attaching an accessory carrier to the hitch.
Carrying Accessories
The Model X towing package has a 2 inch hitch receiver that can support an accessory carrier.
The hitch receiver is designed to support vertical loads of up to 120 lbs (54 kg) when the load is cantilevered rearward within
24 inches (63 cm) of the hitch receiver, such as when carrying bikes on an accessory rack.
When carrying bicycles or other items on the Model X hitch, always check to ensure that the maximum weight is not
exceeded. When calculating weight, remember to include the weight of the accessory carrier. For example, assuming the
carrier weighs 40 lbs, the weight threshold is sufficient for carrying two bicycles weighing approximately 40 lbs each, or four
bicycles weighing approximately 20 lbs each.
CAUTION: The Model X hitch is designed to support up to 120 lbs (54 kg). Exceeding this maximum weight can cause
significant damage.
CAUTION: Do not attempt to install a carrier on a Model X that is not equipped with the towing package. Doing so can
cause significant damage.
To install and use an accessory carrier, the tow hitch must be connected (see Connecting the Tow Hitch on page 541). Then
follow the instructions provided with your accessory carrier. Observe all regulations and legal requirements in your state/
region that apply to carrying accessories.
The Model X towing package includes the wiring necessary for using an accessory carrier equipped with lights (see Electrical
Connections on page 545). The package also includes Trailer Mode software (see Trailer Mode on page 537).
When you connect an accessory carrier's wiring harness, Model X detects a connection for trailer lights and this
indicator illuminates on the instrument panel. 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.
NOTE: Go to www.tesla.com to purchase accessories for your Model X. Although third-party products are available, Tesla

regulations can compromise your safety.
• Adjust side mirrors to provide a clear rearward view without a significant blind spot.
• Engage Trailer Mode (see Trailer Mode on page 537).
Confirm the following:
• Model X 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 loads provided in Carrying Capacity.
• All trailer hitch parts and attachments , safety chains, and electrical connectors are in good condition and are properly
connected. If any problems are apparent, do not tow the trailer.
• Trailer lights (brake lights, turn signal lights, and marker lights) are working properly.
• The trailer tongue is securely connected to the hitch ball.
• Safety chains are properly connected between the trailer and the tow 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.
• All cargo is secured.
• Wheel chocks are available.
• 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 Carrying Capacity.
• If the trailer is equipped with a separate braking system, check that the brakes work and are properly adjusted. To provide
safe stopping ability, you must balance the trailer brakes with the vehicle brakes.
