2023 MERCEDES-BENZ GLE COUPE Owners Manual

The system may be impaired or may not function
in the following situations:
= The gradient is greater than approximately
15%.
= The height of the ball head above level ground
is less than 13.8 in (0.35 m) or more than 21.6 in (0.55 m)

q Using Trailer Maneuvering Assist
Requirements = The vehicle has been started and is stationary.
= A trailer has been detected.
= A calibration drive was performed with the ball
neck used and the current ball head position
(  page 260).
= The gradient is less than approximately 15 %.
= The tailgate is closed.
= The electric parking brake is not applied.
= The driver\bs seat belt is fastened.
Using Trailer Maneuvering Assist\bTo ensure that Trailer Maneuvering Assist
works properly, the taught-in values for eachball head position must be reset a"ser the ball
neck and ball head position have been
changed. A calibration drive must then be per-
formed again. Information on resetting and
the calibration drive (  page 260).Engage reverse gear ^.Press button 1.
The camera image is shown in the central dis-
play.\bThe picture is an example only and is shown without trailer.
You can select various maneuvers in the TrailerManeuvering Assist menu. The maneuver available
depend on the current articulation angle and
length of the trailer.
To adjust the articulation angle: select 3. In
the central display, swipe the entire area of
the camera image to the le"s or right to change
the bend angle.Driving and parking255

orTo activate the straightening maneuver: select
1 .
The system calculates the articulation angle in
such a way that the direction of the trailer at
the time of activation is maintained. There is a
short countersteering movement of the trailer
while the vehicle is backing up, which then
guides it back to the desired line. In this way, the vehicle is aligned straight with the trailer
and, at the same time, the direction of the
trailer is maintained.
or
To activate the 90p maneuver:
= Align the vehicle in the same direction
(line) as the trailer.
= Select (le"s or right) 2.
The system calculates the articulation angle so that the trailer can be maneuvered into a
space perpendicular to the vehicle using the smallest possible angle. A"ser the maneuver,
the vehicle is aligned again in the direction of
the trailer.Accelerate and brake as required.\bThe maximum articulation angle depends on
the 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 23p. The
longer the trailer is, the higher the maximum articulation angle (max. approximately 60p).\bPay attention to your surroundings and beready to brake at all times.

Notes on trailer operation
*NOTE Mercedes-AMG vehiclesObserve the notes in the Supplement.
You could otherwise fail to recognize
dangers.&WARNING Risk of accident due to unsuita-
ble ball neck
If you install an unsuitable ball neck, the trailer
hitch and the rear axle may be overloaded.
This can signi"Ncantly impair the driving char-
acteristics and the trailer may become loose.
There is a risk of fatal injury.Only install a ball neck that complies
with the permissible dimensions and is
designed for the requirements of trailer
operation.Do not modify the ball neck or the trailer
hitch.
The values approved by the manufacturer can be
found on the identi"Ncation plates and in the "Tech-
nical data" section under "Trailer hitch" for the
towing vehicle (  page 399).
&WARNING Risk of accident due to vehi-
cle/trailer combination swerving
If you drive too fast in trailer operation, the
vehicle/trailer combination may start to
swerve.
This could cause you to lose control of the
vehicle/trailer combination. The vehicle/ trailer combination may even rollover.
256Driving and parking

Under no circumstances should you try
to straighten the vehicle/trailer combi-
nation by increasing your speed.Reduce the speed and do not counter- steer.Brake if necessary.*NOTE Damage to the engine resulting
from overheatingIf you subsequently have a trailer cou-
pling retro"Ntted, depending on the vehi-
cle type, changes to the engine cooling
system may be required.
In the case of retro"Ntting a trailer coupling,
please observe the attachment points on the vehicle frame.
Retro"Ntting a trailer hitch is permissible only if a
trailer load is speci"Ned in your vehicle documents.
If this is not the case, the vehicle is not approved for trailer operation.
Further information can be obtained at a quali"Ned
specialist workshop.
For a detachable trailer coupling, it is essential to
comply with the operating instructions of the trailer coupling manufacturer.
Couple and uncouple the trailer carefully. If you
do not connect the trailer to the towing vehicle
correctly, the trailer may become detached.
Observe the following notes on the tongue weight:
= Do not use a tongue weight that exceeds or
falls below the permissible tongue weight
= Use a tongue weight as close as possible to
the maximum tongue weight
Do not exceed the following values:
= Permissible towing capacity
= Permissible rear axle load of the towing vehi-
cle
= Permissible gross weight of the towing vehicle
= Permissible gross weight of the trailer
= Maximum permissible speed of the trailer
Ensure the following before starting a journey: = The tire 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 62 mph (100 km/h) for reasons con-
cerning the operating permit. This also applies in
countries in which the permissible maximum
speed for car/trailer combinations is above
62 mph (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 at speeds greater than
19 mph (30 km/h). This is done regardless of
which drive program has been selected.
Attaching the ball neck
&WARNING Risk of accident and injury due
to incorrectly installed ball neck
If the ball neck is not properly mounted and
secured, it may come loose along with the
trailer while the vehicle is in motion and
