2018 TESLA MODEL X Owner's Manual 

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 50 mm ball
coupling that can support an accessory
carrier.
The ball coupling is designed to support vertical loads of up to 54 kg. When carryingbicycles or other items on the Model X hitch,always check to ensure that the maximum
weight is not exceeded. When calculatingweight, remember to include the weight of the
accessory carrier. For example, assuming the
carrier weighs 14 kg, the weight threshold is
sufficient for carrying two bicycles weighing
approximately 20 kg each, or four bicycles
weighing approximately 10 kg each.
Caution: The Model X hitch is designed to
support up to 54 kg. Exceeding this
maximum weight can cause
significantdamage.
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 85). 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 87). The package also
includes Trailer Mode software (see Trailer
Mode on page 83).

carrier

Towing Capacity
The total trailer weight (including all cargo and additional equipment), and the trailer tongue
weight, must never exceed the following:TiresMaximum Towing Capacity*Maximum Tongue Weight**19"***, 20" or 22"2250 kg90 kg
*Tesla recommends a separate braking system on trailers with a loaded weight of over 450 kg. Thebraking system must be appropriate for the weight of the trailer. Follow the instructions providedby 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 4% 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 Statutory
Plate (see Statutory Plate on page 179).
***A Model X with 19" winter tires supports towing ONLY if equipped with these
specific tires:

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 TiresRear TiresCold TireInflationPressure
245/45R19245/45R1945 psi (310 kPa)255/45R20
265/45R20275/45R2046 psi (320 kPa)265/35ZR22285/35ZR2250 psi (345kPa)Warning: Check tire pressures using an
accurate pressure gauge when tires are
cold. Driving 1.5 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 dangerouslyunder-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:

Trailer Mode
Trailer Mode must always be active when
towing a trailer. When you connect a trailer

1.Connect the wiring on the brake controller
to the appropriate locations on the 4-pin
pigtail connector included with your
Model X.
1 - Brake control output to trailer
2 - Ground
3 - Brake On Signal
4 - 12V Power (20A)
2. Remove the cover located under the
dashboard in the driver

Towing Guidelines
Model X is designed primarily as a passenger-
carrying vehicle. Towing a trailer puts
additional load on the motor, drive train,
brakes, tires, and suspension and
significantlydecreases range. If you decide to tow a trailer,
proceed with caution and follow these general
guidelines:

Warning: You must use the Model X
trailer hitch when towing a trailer. Never
attempt to attach a
different type of
trailer hitch.
To install the trailer hitch:
1. Remove the dust cover from the hitch
housing.
2. Insert the key into the locking cylinder on
the hitch, and turn the cylinder so the top of the key is aligned with the “unlocked”
position.
3. Pull the locking cylinder out of the
adapter approximately 0.5 cm, and turn
clockwise until the red marking on the
cylinder aligns with the white dot.
Warning: Be careful when turning the
locking cylinder. If it does not lock
into the “Open Position”, it
automatically retracts into its original “Closed Position” and can pinch your
fingers.
4. Firmly grasp the hitch from the bottom
and align the triangular-shaped guides at
the sides of the hitch with the
corresponding cutouts in the hitch
housing.
Note: Do not grasp the locking cylinder
because it needs to rotate freely.
5. Push the hitch into the hitch housing until
the locking cylinder rotates approximately 120

2.While firmly holding the bottom of the
hitch (to prevent it from dropping to the ground), pull the locking cylinder out
approximately 0.5 cm, and turn it clockwise until the red marking on the
locking cylinder aligns with the white dot.
At this point, the locking cylinder is locked
in the "open" and the hitch drops out of
the housing.Warning: Be careful when turning the
locking cylinder. If it does not lock
into the “Open Position”, it
automatically retracts into its original “closed" position and can pinch your
fingers.
3. Reinstall the dust cover on the hitch
housing to prevent dirt from accumulating
inside the housing.
4. Close the dust cover on the hitch
