Drive Away Assist cannot always clearly iden-
tify objects and tr

aPc situations. 
Always pay careful attention to the tr
aPc
situation; do not rely on Drive Away
Assist alone. 
Be prepared to brake or swerve as nec-
essar

y, provided the traPc situation per-
mits and that it is safe to take evasive
action. Drive Away Assist is only an aid. It is not a substi-
tut

e for your attention to the surroundings. The
responsibility for safe manoeuvring and parking
remains with you. Make sure that no persons, ani- mals or objects etc. are in the manoeuvring
r
ange.
A risk of collision may occur in the following situa-
tions, forexample: = If the accelerator and brake pedals are inter-
changed.
= If an incorrect transmission position is
engaged.
Drive Away Assist is active under the following
conditions:
= If Parking Assist PARKTRONIC is activated.
= If you shis the transmission position to k or
h when the vehicle is stationary.
= If the detected obstacle is less than approx.
1.0 m away.
= If the manoeuvring assistance function is acti-
vated in the multimedia system.

WARNING Risk of accident due t
o unsuita-
ble trailers
Trailers with a steered axle or a Nsh wheel
canno
t be used with Trailer Manoeuvring
Assist. Due to this, the trailer cannot be manoeuvred
in t
he desired direction and you can cause a
collision or the trailer can overturn. 
Only use Trailer Manoeuvring Assist with
tr
ailers with Nxed drawbars and axles. *
NOTE Damag
e to trailers with a stabilisa-
tion device against swerving In the case of trailers with a stabilisation
de
vice against swerving, the trailer or trailer
tow hitch could be damaged. 
If a trailer coupling with Trailer Manoeu-
vr

ing Assist is used, only use trailers
without a stabilisation device against
swerving. *
NOTE Damag
e due to overhanging loads
in front or drawbar installations The vehicle and the trailer may be damaged
dur

ing manoeuvring due to overhanging loads
at the front of the trailer or drawbar installa-
tions. 
Pay attention to overhanging loads or
dr

awbar installations while manoeuvring. Trailer Manoeuvring Assist assists you when
r

eversing with a trailer. By means of a turning
angle sensor in the trailer coupling, Trailer
Manoeuvring Assist monitors the articulation
angle between the vehicle and trailer and adjusts
it to a speciNed 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 manoeu-
vring area while manoeuvring and parking in/exit-
ing 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 trailer's
current direction. 298
Driving and parking

Trailer Manoeuvring Assist must be taught-in
bef
ore it can adjust the articulation angle
(  page 299).

Drive forwards a short distance with the car/
tr
ailer combination.
The completed teach-in process is shown in
the media display.
% The maximum articulation angle depends on
t

he length of the trailer. This is calculated by
the system by driving the vehicle forwards,
including cornering. Before the length of the
trailer has been calculated, the maximum
articulation angle is approximately 23°. The
longer the trailer is, the higher the maximum
articulation angle (max. approximately 60°). Using Trailer Manoeuvring Assist
