page 298).
In the case of trailers with a stabilisation
device against swerving, the trailer or trailer
tow hitch could be damaged.
If a trailer coupling with Trailer Manoeu‐
#
vring Assist is used, only use trailers
without a stabilisation device against
swerving.
* NOTE Damage due to overhanging loads
in front or drawbar installations
The vehicle and the trailer may be damaged
during manoeuvring due to overhanging
loads at the front of the trailer or drawbar
installations.
Pay attention to overhanging loads or
#

Trailer Manoeuvring Assist assists you when
reversing with a trailer. By means of a turning
angle sensor in the trailer coupling, Trailer
Driving and parking 299
Manoeuvring Assist monitors the articulation
angle between the vehicle and trailer and
adjusts it to a specified value.
Trailer Manoeuvring Assist is only an aid. It is not
a substitute for your attention to the surround‐
ings. The responsibility for safe manoeuvring and
parking remains with you. Make sure that there
are no persons, animals or objects in the
manoeuvring area while manoeuvring and park‐
ing in/exiting parking spaces.
You can either enter the articulation angle value
directly via the multimedia system or use a
straightening manoeuvre. When carrying out a
straightening manoeuvre, the system calculates
the articulation angle automatically and straight‐
ens the vehicle/trailer combination to the trail‐
er's current direction.
Trailer Manoeuvring Assist must be taught-in
before it can adjust the articulation angle
( page 300).
