Important safety instructions G
Ris
kofa ccident
When reversing the vehicle towards the
trailer, mak esure 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 maximu mpermissible gross vehicle
weight of both the towing vehicle and the
trailer
You will fin dthe applicable permissible val-
ues, whic hmust not be exceeded ,inthe vehi-
cle documen ts.
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 Checktrailer hitch locking
mechanism message appears in th emulti-
function display while the vehicle is in motion,
pull over immediately and check whethe rthe
ball coupling is correctly engaged. G
Risk of accident
Always observ ethe 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 appl yingc onstant slight
pedal pressure. This causes the brake system
to overheat, increases the brakin gdistance
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. Trailer towing
