Maintenance
Correct operation is only possible if the towball
and its carrier remain clean.

jet wash, the towbar harness socket carrier must
be folded away, the towball removed and the
protective blanking plug inserted in the carrier.
For any work on the towbar, go to a PeugeOt
dealer or a qualified workshop.
Stowing the towball
It is recommended that the removable towball
be safely stowed, preferably in a storage space
below the boot floor.
Attach the towball using the bag tie cord.
Never leave the removable towball
unsecured in the boot. In the event of
sudden braking, a towball left loose
in the boot could present a danger to
passengers in the vehicle.
Furthermore, the towball and the boot
risk being damaged.
