Towing a trailer
Notes on towing a trailer
Important safety notes
G WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
G WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi-
cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
G WARNING
If you install a ball coupling other than the one
delivered with the vehicle, the trailer tow hitch
and the rear axle may be overloaded. This
applies especially if the ball coupling in ques-
tion is longer or angled differently. This could
seriously impair the driving characteristics
and the trailer can come loose. There is a risk
of an accident.
Only install the ball coupling delivered with
the vehicle or a ball coupling that is designed
to meet your trailer towing requirements. Do
not modify the ball coupling or the trailer tow
hitch.
G WARNING
If the ball coupling is not installed correctly or
not secured with the bolt provided and the
corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
Always install and secure the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
Please observe the manufacturer's operating
instructions for the trailer coupling if a
detachable trailer coupling is used.
Exceeding the maximum permissible nose-
weight may cause damage to the following:
R
your vehicle
R
the trailer
R
the ball coupling
R
trailer tow hitch
The vehicle/trailer combination could
become unstable.
If the noseweight used is lower than the min-
imum permissible noseweight, the vehicle/
trailer combination could also become unsta-
ble.
To avoid hazardous situations:
R
make sure to check the noseweight before
each journey
R
use a drawbar noseweight as close as pos-
sible to the maximum noseweight
R
do not exceed the maximum permissible
noseweight
R
do not use a noseweight lower than the
minimum permissible trailer drawbar nose-
weight
When backing up the vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle.
The applicable permissible values, which
must not be exceeded, can be found:
R
in your vehicle documents
R
on the type plate of the trailer tow hitch and
trailer
R
on the vehicle identification plate
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
