9 Warning
Towing a trailer is permitted only
when the coupling ball bar is fitted
correctly. If the coupling ball bar
cannot be properly attached, seek
the assistance of a workshop.
Eye for break-away stopping cable
In the case of trailers with brakes,
attach the break-away stopping cable
to the eye - not to the coupling ball
bar.
Dismounting the coupling ball bar
Unlock coupling ball bar and remove
key. Push lever to the left, towards the
coupling ball bar and turn it
downwards. Pull coupling ball bar out
of coupling housing.
Remove any rust or dirt from area
around the coupling housing and
coupling ball bar connection before
inserting sealing plug in the hole.
Place the coupling ball bar in the bag
supplied, fasten it with the strap and
stow it below the floor cover in the
load compartment.
Do not use steam-jet cleaners or
other high-pressure cleaners to clean
the coupling ball bar.

Trailer stability assist

If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking
ceases. While system is working keep
steering wheel as still as possible.
Trailer stability assist (TSA) is
a function of the Electronic Stability
Control 3 133.
