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
o
verrun brake. 
Secure the trailer against rolling away. 
Disconnect the electrical connection between
t

he vehicle and the trailer. 
Uncouple the trailer. 
Place the cover cap on the ball head.
% Trailers with LED lighting: aser uncoupling t
he
trailer, switch the vehicle on and then oM
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.
Observe the following for your own safety and
that of other road users:
= always adhere to the permissible load
capacity of the trailer hitch. Driving and parking
279

=
alw ays observe the permissible rear axle
load of the towing vehicle.
= use the bicycle rack only to transport bicy-
cles.
= always properly secure the bicycle rack by
attaching it to the ball head.
= 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
tr
ailer hitch, retract the ball neck. *
NOTE The oper
ating permit may be invali-
dated due to the illegal installation of
trailer hitches The installation !

Observe the notes on driving with a roof load,
tr
ailer or fully laden vehicle ( page 173).
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 381).
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.
Therefore, observe the following notes:
= mount heavy 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
mo
ving 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 Observe the following information when you are
