Pay attention toove rhanging loads or

ailer Manoeuv ring Assist assists you when
re ve rsing with a trailer. Using there ve rsing cam-

ve hicle and trailer and adjusts it toa speci/ed

speed.
Tr ailer Manoeuv ring Assist is only an aid. It is not

are no persons, animals or objects in the manoeu- vring area while manoeuvring and parking in/exit-

Yo u can either enter the articulation angle value
directly via the multimedia system or use a

The system calculates the articulation angle in
such a wayth at the direction of the trailer at
th e time of activation is maintained. There is a
short countersteering mo vement of the trailer
while theve hicle is reve rsed, which then
guides it back tothe desired line. In this wa y,
th eve hicle is aligned st raight with the trailer
and, at the same time, the direction of the
trailer is maintained. #
Accelerate and brake as requ ired.
% The maximum articulation angle depends on
the length of the trailer. This is calculated by
th e system bydriving theve hicle forw ards,
including cornering. Before the length of the
trailer has been calcula ted, the maximum
articulation angle is appr oximately 23°. The
longer the trailer is, the higher the maximum
articulation angle (max. appr oximately 60°).
