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 coupling 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.
Notes on towing a 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.
You will find the values approved by the man-
ufacturer on the vehicle identification plates
and those for the towing vehicle in the "Tech-
nical data" section.
You will find installation dimensions and loads
in the "Technical data" section
(
Y
page 253).
The maximum drawbar load of the trailer
drawbar on the ball coupling is 80 kg. How-
ever, the actual noseweight must not exceed
the value given on the trailer coupling and
trailer identification plates. The lowest weight
applies.
!
Use a noseweight as close as possible to
the maximum permissible noseweight. Do
not use a noseweight of less than 50 kg,
otherwise the trailer may come loose.
Bear in mind that the payload and the rear
axle load are reduced by the actual nose-
weight.
i
The height of the ball coupling changes
with the load of the vehicle. If necessary,
use a trailer with a height-adjustable trailer
drawbar.
Coupling up 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
trailer drawbar.
!
Do not disconnect a trailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the rebound-
ing of the overrun brake.
X
Position the trailer level behind the vehicle.
X
Couple up the trailer.
X
Establish the electrical connection
between the vehicle and the trailer.
