Risk of accident
The ball coupling is only securely mounted
when the green area on the handwheel is
aligned with the white dot on the ball coupling and the key can be removed. If the ball cou-
pling is not securely mounted, it may come
loose.
The ball coupling must be locked and the key
must be removed when towing a trailer. This
is the only way to guarantee that the ball cou-
pling is secured and cannot come loose while
the vehicle is in motion. If the ball coupling
cannot be locked and the key cannot be
removed, remove the ball coupling and clean
it.
If the ball coupling can still not be fitted
(locked) after it has been cleaned, remove the
ball coupling. The trailer tow hitch must then
not be used to tow a trailer, as safe operation
is not guaranteed.
Have the entire trailer coupling checked at a
qualified specialist workshop. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose. In par-
ticular, work relevant to safety or on safety-
related systems must be carried out at a quali-
fied specialist workshop. :

with a trailer. The vehicle is not lowered to
the high-speed level even if you are travel-
ling at higher speeds.
This also applies when using accessories
that are plugged into the socket of the
trailer coupling (e.g. a bicycle rack).
Decoupling a trailer G
Risk of injury
Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your hand could
become trapped between the bumper and
drawbar.

den vehicle rises slightly. Make sure that you
or others are not injured in the process.
X Remove the trailer cable and decouple the
trailer.

G
Risk of accident
When reversing the vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle.
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the following values are not
exceeded:
R the permissible trailer drawbar noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
You will find the applicable permissible val-
ues, which must not be exceeded, in the vehi-
cle documents. 196

X Remove fire extinguisher ;. Vehicle tool kit, TIREFIT, jack and
"Minispare" emergency spare
wheel*
The vehicle tool kit, TIREFIT, jack and
"Minispare" emergency spare wheel are in the
stowage space under the luggage compart-
ment floor. G
Risk of injury
The jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed.
You must use axle stands if you are carrying
out work on the vehicle.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar objects as a jack underlay.
Otherwise, the jack will not be able to achieve
its load-bearing capacity due to the restricted
height.
Do not start the engine at any time while a
wheel is being changed. Do not lie under the vehicle when it is being
supported by the jack. If you do not raise the
vehicle as described, it could slip off the jack
(e.g. if the engine is started or if a door or the
tailgate is opened or closed) and you could be
seriously injured.
i When using the jack, you should also
observe the safety notes in the "Flat tyre"
section (Y page 262).
X Open the luggage compartment floor
(Y page 208).
