WARNING Risk of becoming tr
apped when
disconnecting the trailer cable
Vehicles with rear axle level control: The v
ehi-
cle may lower when the trailer cable is discon-
nected.
This could result in you or other people
becoming trapped if parts of your or their
body 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. 
Secure the trailer against rolling away. 
Disconnect the electrical connection between

again. Bicycle rack function
&
WARNING Risk of an accident if t
he bicy-
cle rack is used incorrectly
The bicycle rack may become detached from
t
he vehicle in the following cases:
= the permissible load capacity of the trailer
hitch is exceeded.
= the bicycle rack is used incorrectly.
= the bicycle rack is secured to the ball neck
beneath the ball head. 298
Driving and parking

Observe the following for your own safety and
t hat of other road users:
= always adhere to the permissible load
capacity of the trailer hitch.
= always observe the permissible rear axle
load of the towing vehicle.
= use the bicycle rack only to transport bicy-
cles.
= always mount the bicycle rack properly by
attaching to the ball head and the ball
neck guide pin, if possible.
= when transporting four bicycles, always
use bicycle racks that have additional sup-
port on the ball neck guide pin.
= use only bicycle racks approved by
Mercedes-Benz.
= always observe the bicycle rack operating
instructions. *
NOTE Damag e to or breakage of the trailer
hitch due to unsuitable or improperly used
bicycle rack. 
Only use bicycle racks approved by
Mer
cedes-Benz properly as described
below. *
NOTE Incr
eased risk of damage to prop-
erty due to folded-out ball neck 
When the trailer is not coupled or the
bicy
cle rack is attached, fold in the ball
neck or, in the case of a fully electric
trailer hitch, retract the ball neck. *
NOTE The oper
ating permit may be invali-
dated due to the illegal installation of
trailer hitches The installation !

The following bicycle rack designs are possible:
= When mount
ed by attaching to ball head 1,
the maximum load capacity is 75 kg. You can
transport up to three bicycles.
= When mounted on ball head 1 and guide pin
2, the maximum load capacity is 100 kg. You
can transport up to four bicycles.
The maximum load capacity is calculated from the
weight of the bicycle rack and the bicycle rack
load.
Observe the notes on driving with a roof load,
trailer or fully laden vehicle (  page 178).
When using a bicycle rack, set the tyre pressure
for increased load on the rear axle of the vehicle.
Further information on the tyre pressure can be
found in the tyre pressure table (  page 414).
Notes on loading
The larger the distance between the load's centre
of gravity and the ball head, the greater the load
on the trailer hitch. Observe the following notes:
= mount hea
vy bicycles as close to the vehicle
as possible
= always distribute the load on the bicycle rack
as evenly as possible across the vehicle's lon-
gitudinal axis
Mercedes-Benz recommends removing all detach-
able parts 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

The v
ehicle is not suitable for the use of tow bar
systems that are used for Oat towing or dinghy
towing, for example. Attaching and using tow bar
systems can result in damage to the vehicle.
When you are towing a vehicle with tow bar sys-
tems, safe driving characteristics cannot be guar- anteed for the towing vehicle or the towed vehicle.
The v

ehicle-trailer combination may swerve from
side to side.
