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's locking cylinder
and store the hitch in a secure location.
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 13-pin
wiring connector is provided near the hitch support's
wiring plugs from most types of trailers.
1. Left Turn Signal (Yellow)
2. Rear Fog (Blue)
3. Ground for Pins 1-8 (White)
4. Right Turn Signal (Green)
5. Right Tail Lamp (Brown)
6. Stop Lamps (Red)
7. Left Tail Lamp (Black)
8. Reverse Lamps (Pink)
9. Low Voltage Power - Permanent (Orange)
10. Low Voltage Power - Switched/Ignition (Grey)
11. Ground for Pin 10 (Black/White)
12. Trailer Brake Control Output (Light Grey)
13. Ground for Pin 9 (Red/White)
NOTE:
All pins have Low Voltage power.
NOTE:
It is the driver's responsibility to ensure that all
electrical connections are working and all trailer lights
are operating before and during towing. You must
perform manual checks.
NOTE:
Loss of trailer lights when towing may be the
result of a fault in the trailer wiring or excessive power
consumption by the lights connected to the trailer
output(s). When this occurs, a red Trailer Mode icon
appears on the touchscreen. Fix any issues with the
wiring and/or reduce the number of lights connected to
the trailer output(s), then toggle Trailer Mode off and on
again.
NOTE:
If a trailer fog light is detected, Model X disables
its rear fog light (if equipped).
Plugging trailer wiring into the Model X electrical
connector automatically engages Trailer Mode (see
).
WARNING:
Use only the electrical connection
designed by Tesla. Do not attempt to directly
splice or attempt to connect a trailer’s electrical
wiring using any other method. Doing so can
damage the vehicle electrical system and cause
malfunctions.
CAUTION:
Always ensure that the trailer electrical
cable does not contact or drag on the ground and
there is enough slack in the cable to allow for
turns.
Impact on Range
Towing 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.
