Pay attention toove rhanging loads or
dr aw bar ins tallations while manoeuvring. Tr
ailer Manoeuv ring Assist assists you when
re ve rsing with a trailer. By means of a turning
angle sensor in the trailer coupling, Trailer
Manoeuv ring Assist moni tors the articulation
angle between theve hicle and trailer and adjusts
it to a speci/ed value.
Tr ailer Manoeuv ring Assist is only an aid. It is not
a substitute foryo ur attention tothe sur round-
ings. The responsibility for safe manoeuvring and
parking remains with you. Make sure that there
are no persons, animals or objects in the manoeu-
vring area while manoeuvring and parking in/exit-
ing parking spaces.
Yo u can either enter the articulation angle value
directly via the multimedia system or use a Driving and parking

tening manoeuvre. When ca rrying out a
straigh tening manoeuvre, the system calculates
th e articulation angle automatically and straight-
