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″ 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 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.

To install and use an accessory carrier, the tow hitch must be connected (see Connecting the Tow Hitch). 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 ). The package also includes Trailer Mode software (see Trailer Mode).

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.

Towing Capacity

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

SAE Class III – 5000 lb (2300 kg)

SAE Class II — 3500 lb (1588 kg)

Tires Maximum Towing Capacity* Maximum Tongue Weight**
275/45R20 110 V / Y SAE Class III – 500 lb (230 kg)
285/35R22 106 W SAE Class II – 350 lb (158 kg)

*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).

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):

Before Towing a Trailer

Before towing a trailer, you must do the following:

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.

Trailer Mode

Trailer Mode must always be active when towing a trailer. When you connect a trailer’s electrical connection, Model X automatically engages Trailer Mode. When you disconnect the trailer’s electrical connection, Trailer Mode disengages. To engage or exit Trailer Mode manually, touch Controls > Pedals & Steering > Trailer Mode on the touchscreen. One of the following indicators display on the instrument panel:

Some Autopilot features (Autosteer, Summon, Lane Assist, etc.), as well as rear parking sensor functionality, may not be available when Trailer Mode is enabled. In addition, some features may operate differently. For example:

  • 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 .
  • The air suspension system 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) is significantly limited.

Trailer Brakes

When towing a loaded trailer that weighs more than 1000 lbs (450 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:

    Connect the wiring on the brake controller to the appropriate locations on the 4-pin pigtail connector.

1 — Brake control output to trailer

3 — Brake On Signal

4 — Low Voltage Power (20A)

  • Remove the cover located under the dashboard in the driver’s side foot well.
  • Peel back the carpet to expose Model X’s 4-pin connector on the wiring harness.
  • Connect the pigtail connector to the vehicle wiring connector.
  • 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).
    • 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.
