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 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. Using the reversing cam-
era, it monitors the articulation angle between the
vehicle and trailer and adjusts it to a speciNed
value. Trailer Manoeuvring Assist also limits your
speed.
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
ar

e 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 or the 90° manoeuvre.
When carrying out a straightening manoeuvre, the
system calculates the articulation angle automati-
cally and straightens the vehicle/trailer combina-
tion to the trailer's current direction.
Observe the notes on towing a trailer
(  page 310).

tions:

Driving and parking

The system may be impaired or may not function
in t
he following situations:
= The gradient is greater than approximately
15 %.

qUsing Trailer Manoeuvring Assist
Requirements:
= The vehicle has been started and is stationary.
= A trailer is selected in the Vehicle menu
(  page 315).
= A trailer has been detected.
= The gradient is less than approximately 15 %.
= The tailgate is closed.
= The electric parking brake is not applied.
= The driver's seat belt is fastened. Using Trailer Manoeuvring Assist

Engage reverse k g
ear. 
Press button 1.
The camer

a image is shown in the central dis-
play. You can select various manoeuvres in the Trailer
Manoeuvr

ing Assist menu. The manoeuvres avail-
able depend on the current articulation angle and
length of the trailer. 
To adjust the articulation angle: select 3. In
t
he central display, swipe the entire area of
the camera image to the les or right to change
the bend angle.
or 
To activate the straightening manoeuvre:
select 1.
The sy

stem calculates the articulation angle in
such a way that the direction of the trailer at
the time of activation is maintained. There is a Driving and parking
309

short countersteering movement of the trailer
while t
he vehicle is reversed, 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 90° manoeuvre:
= Align t

he vehicle in the same direction
(line) as the trailer.
= Select (les or right) 2.
The system calculates the articulation angle
so that the trailer can be manoeuvred into a
space perpendicular to the vehicle using the
smallest possible angle. Aser the manoeuvre,
the vehicle is aligned again in the direction of
the trailer. 
Accelerate and brake as required.
% 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
ar
ticulation angle (max. approximately 60°).
% Pay attention to your surroundings and be
r
eady to brake at all times. Trailer hitch

he vehicle
level may be changed unintentionally, e.g. by
other persons. If you couple or uncouple the
trailer during this time, you may become trap-
ped. In addition, other people could become
trapped if their limbs are between the vehicle
body and the tyres or underneath the vehicle.

WARNING Risk of being cr
ushed and
becoming trapped when uncoupling a
trailer
When uncoupling a trailer with an engaged
iner
tia-activated brake, your hand may
become trapped between the vehicle and the
trailer drawbar. 
Do not uncouple trailers with an engaged
o
verrun brake. *
NOTE Damag
e during uncoupling with an
engaged overrun brake The vehicle may be damaged if you uncouple
wit
h an engaged overrun brake. 
Do not uncouple trailers with an engaged

verrun brake. &
WARNING Risk of becoming tr
apped when
disconnecting the trailer cable
Vehicles with level control system: t
he vehicle
may lower when you disconnect the trailer
cable.
This could result in other people becoming
trapped if their limbs are between the vehicle
body and the tyres or underneath the vehicle. 
Make sure nobody is underneath the
v

ehicle or in the immediate vicinity of the
wheel arches when you disconnect the
trailer cable. *

= the bicycle rack is secured to the ball neck
beneath the ball head.
Observe the following for your own safety and
that of other road users:
= always adhere to the permissible load
capacity of the trailer hitch.

Mercedes-Benz recommends removing all detach-
able par ts from bicycles (e.g. baskets, child seats,
rechargeable batteries) before loading them onto
the bicycle rack. This will improve the aerody-
namic resistance and centre of gravity of the bicy-
cle rack.
Always secure the bicycles to prevent them from
moving around and check them at regular inter-
vals to ensure that they are secure.
Do not use tarpaulins or other covers. The driving
characteristics and rear view may be impaired. In
addition, aerodynamic resistance and the load on
the trailer hitch will increase. Load distribution on the bicycle rack
1 Vertical distance between centre of gravity
and ball head
2 Horizontal distance between centre of gravity
and ball head
3 The centre of gravity is on the vehicle's centre
axis
