8. Remove the key and store it in a safe
place (preferably inside the vehicle).
Note: The key can be removed only if the
hitch is locked. This indicates a proper
connection. Do not use the hitch if the key
is not removed.
Note: Tesla recommends making a note of
the key code. You need this key code if
you lose the keys and need to order a
replacement.
Disconnecting the Tow Hitch
After towing, remove the hitch:
1. Insert the key and turn to align the top of
the key with the Unlock icon.
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 Lock icon shifts to the
top. At this point, the locking cylinder is
unlocked in the "Open" position 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 by snapping in the
push clips.

4. Close the dust cover on the hitch's locking
cylinder and store the hitch in a secure
location.
Note: To maintain the hitch, regularly
grease its surface with non-resinous
grease.
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 7-pin wiring connector is
provided near the hitch support's wiring plugs
for most types of trailers.

Note: Pins 9-13 are not supported at this time
because Model 3 is not currently equipped
with brake controllers.
Note: All pins have 12V 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 blown fuse. Model 3 does
