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 Model 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 Model 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.

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 537). 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 541). The package also includes Trailer Mode software (see Trailer Mode on page 533).
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
recommends and supports only Tesla-approved products (see Parts and Accessories on page 786). The accessory products
available for your Model X vary based on market region. Before attempting to install a non-Tesla carrier, review the product
information to ensure compatibility.
NOTE: When not in use, the hitch receiver should be removed and stored in a dry location to prevent rust and corrosion. Keep
the dust cover over the hitch housing to prevent dirt and debris from entering (see Disconnecting the Tow Hitch on page 541).
CAUTION: A carrier may obscure your view from the rear view mirror or the rear camera(s). In addition, some Autopilot
features may not function as expected.
WARNING: 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.

*Tesla recommends a separate braking system on trailers with a loaded weight of over 1000 lbs (450 kg). The braking system
must be appropriate for the weight of the trailer. 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. It must not be less than 10% of
the trailer load. 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. The GVWR is printed on the Vehicle Certification Label (see Vehicle
Certification Label on page 834).
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.
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 Model X.

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):
Front Tires

Rear Tires

Cold Tire Inflation Pressure

245/45R19

245/45R19

45 psi (310 kPa)

255/45R20

275/45R20

46 psi (320 kPa)

285/35ZR22

50 psi (345 kPa)

265/45R20

265/35ZR22

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 is
dangerously under-inflated.
WARNING: Never attempt to tow a trailer when a Model X 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.
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.
• Set the Suspension height to Low (touch Controls > Suspension > Low).
• Observe all regulations and legal requirements in your state/region that apply to trailer towing. Failure to comply with
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 533).
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.

Owners Manual
WARNING: Never attempt to connect trailer brakes directly to the vehicle braking system. Doing so can cause damage
to the vehicle and the trailer, and can cause the braking system to malfunction, resulting in serious injury or death.
Towing Guidelines
Model X 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. Keep in mind that 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 a 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 bulbs are still working. When towing a trailer, the turn
signal arrows on the vehicle instrument cluster flash as normal, even if the bulbs on the trailer are burned out.
• Periodically confirm the cargo is secure.
• Periodically confirm the trailer brakes are working.
• Avoid parking on a grade (see Parking with a Trailer on page 537).
• Regularly confirm that all towing components are securely tightened.
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:
• One person presses and holds the brake pedal.
• A second person places the wheel chocks under the wheels on the downgrade side of the vehicle's tires.
• 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 487) is not engaged. If Vehicle Hold is
braking Model X, the Vehicle Hold indicator light displays on the instrument panel. To disengage Vehicle Hold, press and
release the brake pedal.
• 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, injury, or death.
Trailer Sway Mitigation
When trailer sway is detected, the Model X electronic stability control system attempts to apply the appropriate amount of
braking to minimize trailer sway. The instrument panel 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.
Connecting the Tow Hitch
The Model X towing package includes a weight-carrying hitch with a 2” x 2” removable hitch receiver. When not in use, the
hitch receiver should be removed and stored in a dry location to prevent rust and corrosion. Keep the dust cover over the hitch
housing to prevent dirt and debris from entering.
