– There must be a clearly visible space between
the handwheel and the ball hitch; the gap J
between handwheel and ball hitch must be
around 5 mm.
– It must be possible to press locking balls C
completely into the shank with their full
diameter.
If the ball hitch is not pretensioned, tension it
as described below:
f The ball hitch must be unlocked, i.e. the arrow
on the key must point to the "lock open"
symbol on the handwheel.

Trailer Hitch
f Hold the ball hitch with your left hand.
Pull the handwheel out in arrow direction 1
with your right hand and then, with the
handwheel still pulled out, turn it in arrow
direction 2 until it engages.
The ball hitch has now been pretensioned.
If the ball hitch cannot be pretensioned, it must not
be used.
f Consult a qualified specialist workshop. We
recommend that you use a Porsche partner for
this work since these are staffed with trained
personnel and have the necessary parts and
tools.
Attaching ball hitch to the vehicle
When inserting ball hitch E, do not touch
handwheel D with your hand. When the ball hitch
locks into place, the handwheel rotates back
counter-clockwise and comes into contact with
the ball hitch again.
1. Insert tensioned ball head E into mounting
tube K in the direction of the arrow and push
it up firmly until the ball hitch snaps into place.
