Towing
Connecting the Tow Hitch
The Model 3 towing package includes a
weight-carrying hitch with a 50 mm ball
coupling. When not in use, the hitch should be
removed and stored in a dry location to
prevent rust and corrosion. Keep the dust
cover over the hitch housing to prevent dirt
and debris from entering.
Warning: You must use the Model 3 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:
1. Remove the dust cover from the hitch
housing by inserting a small object, such
as a flat screwdriver, into the push clips on
each side of the dust cover. Turn the push
clips until they are in an unclasped
position, take them out, and remove the
dust cover.

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 "Open"
position.
3. Pull the locking cylinder out of the
adapter approximately 0.5 cm, and turn
clockwise until the Unlock icon is fixated
at the top of the locking cylinder.
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 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 quickly rotates
counter-clockwise and automatically locks
into the "Closed" position.
6. Check to confirm that the hitch is fully
inserted into the housing by pulling down
on the hitch. The hitch should not drop
when you pull down.
Note: If the hitch does not lock into the
housing, it falls out when you pull down
on the hitch.
7. Turn the key so the arrows align with the
Lock icon on the locking cylinder.
