Uncoupling a trailer
Important safety notes
G
WARNING
If you uncouple a trailer with an engaged over-
run brake, you could trap your hand between
the vehicle and the trailer drawbar. This poses
a risk of injury.
Do not uncouple a trailer with an engaged
overrun brake.
G
WARNING
Vehicles with level control:
If you disconnect the trailer cable, the vehicle
is lowered. This can cause you or others to
become trapped between the vehicle body
and tyres, or underneath the vehicle. This
poses a risk of injury.
Make sure that no-one is in the immediate
vicinity of the wheel arch or underneath the
vehicle when disconnecting the trailer cable.
!
Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your vehicle could
be damaged by the rebounding of the overrun
brake.
!
Remove the adapter cable before folding in
the ball coupling. You could otherwise dam-
age the rear bumper and the adapter cable.
