Towing a trailer
– Never press the button 1 / 2 if a trailer is
hitched up or if a luggage rack or other ac-
cessories are mounted on the towing brack-
et – risk of accident!
Note
– The eye 4 on the towing bracket is inten-
ded only for securing the breakaway cable of
the trailer.
– Never attempt to interfere with the move-
ment of the towing bracket, for example
with tools, while it is swivelling. This can
cause damage, in which case the trailer can
no longer be towed safely.
– Malfunctions may occur when extending
and retracting the towing bracket in very
cold weather. If this should happen, press
and hold the button until the towing brack-
et reaches its final position (the operating
position or fully retracted position). In such
cases, it is often sufficient to leave the vehi-
cle in a warmer room (e.g. garage).
– Any noises which may be heard when the
button is pressed are quite normal and no
cause for concern.
– Only use the towing bracket when it has
swivelled out fully and engaged securely.
– You should have the towing bracket checked
by a qualified dealership if any faults occur
in the electrical system or in the towing
bracket itself.
CAUTION
Driving with a trailer or caravan
Applies to: vehicles with swivelling towing bracket
– Do NOT hold a high-pressure cleaner direct-
ly at the seal of the towing bracket or the
trailer socket. This may cause damage to
the seal, with the result that moisture can
enter and damage the system.
Towing bracket
Check that the coupling meets the relevant coun-
try-specific regulations and is not worn.
– The swivelling unit, accessories and parts of
the vehicle could be damaged if you press
the button 1 / 2 while a trailer is hitched
up or if a luggage rack or other accessories
are fitted to the towing bracket.
Electronic stabilisation control (ESC)
The ESC – in particular in conjunction with the
trailer stabilisation system ðpage 163 – makes
it easier to stabilise a trailer if it starts to skid or
sway. You should therefore keep the ESC switch-
ed on at all times.
– If you have plugged an adapter into the
trailer socket, this could damage the bump-
er and trailer socket when the towing brack-
et is retracted. Remove the adapter before
retracting the towing bracket.
Stabiliser
Swaying and pitching can be reduced by attach-
ing an extra stabiliser to the trailer. Degrease and
clean the ball joint before using a stabiliser. The
stabiliser can be purchased and installed at a
qualified workshop.
Note
Retract the towing bracket or detach it when
there are no trailers, bicycles or similar loads
attached to it. This applies especially if the
number plate or rear vehicle lighting is
masked by the unused towing bracket. Ob-
serve the relevant local regulations for the
use of a towing bracket.
Clean the ball coupling before using a trailer
without a stabiliser and apply multi-purpose
grease to it. Repeat this application regularly if
you tow a trailer frequently.
Power supply
When you switch off the ignition, the power sup-
ply to the trailer is not interrupted as long as the
energy management system does not intervene.
