Uncoupling a trailer
G Risk of injury

unladen vehicle rises slightly. The vehicle then
lowers to driving level.
Make sure that nobody is in the vicinity of the
wheel arch or the underbody. You could oth-
erwise trap yourself or others.

Notes on towing a trailer
Important safety instructions
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:
the permissible trailer drawbar noseweight
R
the permissible trailer load
R
the permissible rear axle load of the towing
R
vehicle
the maximum permissible gross vehicle
R
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.
G
Risk of accident
If the Check trailer hitch locking
mechanism message appears in the multi-
function display while the vehicle is in motion,
pull over immediately and check whether the
ball coupling is correctly engaged.
G
Risk of accident
Always observe the maximum speed permit-
ted in Germany for vehicle/trailer combina-
tions, even in countries where higher speeds
are permitted. This lowers the risk of an acci-
dent.
G
Risk of accident
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely.
G
Risk of accident
On no account should you attempt to draw the
vehicle/trailer combination out by increasing
speed.
