Warning: The trailer tongue weight must
be approximately 10% of the total trailer weight without exceeding the maximumtongue weights provided in Carrying
Capacity. Loads that are balanced over
the 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
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:

Note: Always remove the ball mount before
installing or removing the hitch receiver from
the vehicle (see Attaching and Removing the
Ball Mount on page 102).Warning: You must use the Model X trailer
hitch when towing a trailer. Never attempt
to attach a different type of trailer hitch.
Note: Always attach safety chains when
towing. Cross the chains under the trailer
tongue and attach to the trailer eyelets to
ensure the security of the trailer load.
To install the trailer hitch receiver:
1. Remove the dust cover from the hitch
housing.
Note: Newer versions of Model X have two
push clips that secure the dust cover to
the vehicle. To open, use a sharp object,
such as a

3.Pull the locking cylinder out of the
adapter approximately 1/8" (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

Attaching and Removing the Ball
Mount
The Model X 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 X hitch receiver supports a ballmount up to 8” with a rise of up to 0.75”. Do
not use any type of drop ball mount.
To attach a ball mount:
1. If necessary, remove the cotter pin from
the locking bolt and slide the locking bolt out of the hitch assembly.
2. Slide the ball holder into the hitch
assembly.
3. Align the hole in the ball holder with the
one in the hitch assembly.
4. Slide the locking bolt through the hitch
assembly/ball holder.
5. Insert the cotter pin in the hole at the end
of the locking bolt.
To remove a ball mount:
1. Remove the cotter pin from the locking
bolt and slide the locking bolt out of the
ball holder/hitch assembly.
2. Pull the ball holder out of the hitch
assembly.
Electrical Connections
Regulations require all trailers to be equipped
with tail lights, brake lights, side marker lights,
and turn signals. To provide power for trailer
lighting, a built-in seven-way wiring connector (SAE J560) is attached near the tow hitch.Most trailer wiring plugs can be attached tothis connector.

Impact on RangeTowing a trailer and carrying accessories
increases vehicle weight and drag. As a result,
driving range can decrease significantly.
Although Trip Planner attempts to adjust
estimates based on Trailer Mode, actual
energy consumption may vary. Plan trip length
and charging destinations accordingly.
