If you couple up a trailer, make sure that you
have correctly established the electrical con-
nection. This can be accomplished by checking
the trailer lighting.
Towing a trailer
Important safety notes
G
WARNING
You could lose control of the vehicle/trailer
combination if it begins to swerve. The vehi-
cle/trailer combination could even overturn.
There is a risk of an accident.
On no account should you attempt to
straighten out the vehicle/trailer combina-
tion by increasing speed. Decrease your
speed and do not countersteer. Brake if nec-
essary.
G
WARNING
If the maximum permissible load for a carrier
system is exceeded, the carrier could come
loose from the vehicle and endanger other
road users. There is a risk of an accident and
injury.
Never exceed the maximum permissible load
when using a carrier.
!
If you have a trailer tow hitch retrofitted,
changes to the engine cooling system may be
necessary, depending on the vehicle type.
If you have a trailer tow hitch retrofitted,
observe the anchorage points on the chassis.
Retrofitting a trailer tow hitch is only permissible
if a trailer load is specified in your vehicle docu-
ments. If this is not the case, then the vehicle is
not approved for towing a trailer.
For more information, please contact a qualified
specialist workshop.
Exceeding the maximum permissible nose-
weight of the trailer drawbar on the ball coupling
may cause damage.
Damage may be caused to the following:
R
towing vehicle
R
trailer
R
ball coupling
R
trailer tow hitch
The vehicle/trailer combination could become
unstable.
The vehicle/trailer combination could also
become unstable if the noseweight used is lower
than the minimum permissible noseweight.
To avoid hazardous situations:
R
make sure to check the noseweight before
each journey
R
use a noseweight as close as possible to the
maximum noseweight
R
do not exceed the maximum permissible
noseweight
R
do not use a noseweight lower than the min-
imum noseweight
Make sure that the following values are not
exceeded:
R
the permissible 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

The applicable permissible values, which must
not be exceeded, can be found:

WARNING
If you release the ball coupling or it does not
engage correctly when folding in, it will swing
out. Within pivoting range of the ball coupling,
there is an increased risk of an accident and
injury.
Only release the ball coupling if the pivoting
range is unobstructed. Always make sure that
the ball coupling engages when folding in.
When reversing the towing vehicle, make sure
there is nobody between the trailer and the vehi-
cle.
