2022 MERCEDES-BENZ GLE COUPE Owners Manual


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. Trailer Manoeuvring Assist must be taught-in
bef
ore it can adjust the articulation angle
( page 302).
Observe the notes on towing a trailer
( page 303).
System limits
Observe the system limits of the following func-
tions:
= Active Parking Assist (  page 296)
= 360° Camera ( page 288)
= Reversing camera ( page 285)
The system may be impaired or may not function
in the following situations:
= The gradient is greater than approximately
15 %.
Using Trailer Manoeuvring Assist
Requirements:
= The vehicle has been started and is stationary.
= A trailer has been detected.
= The gradient is less than approximately 15%. =
The electr ic parking brake is not applied.
Teaching in Trailer Manoeuvring Assist 
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°). 302

To adjust the articulation angle: select

Ensure the following before starting a journey:
= The tyr
e pressure on the rear axle of the tow-
ing vehicle is set for a maximum load
= The lighting of the connected trailer is opera-
tional
In the event of increased rear axle load, the car/
trailer combination must not exceed a maximum
speed of 100 km/h for reasons concerning the
operating permit. This also applies in countries in
which the permissible maximum speed for car/
trailer combinations is above 100 km/h.
Vehicles with AIRMATIC or E-ACTIVE BODY CON-
TROL: if the socket of the trailer hitch is occupied,
e.g. by a trailer or rear bicycle rack, the vehicle is
set to the normal level regardless of the drive pro-
gram at speeds greater than 30 km/h.
