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 qualifiedspecialist 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
trailer
The applicable permissible values, which must
not be exceeded, can be found:
R in your vehicle documents
R on the type plates for the trailer
R on the vehicle identification plate
If the values differ, the lowest value applies.
You will find permissible trailer loads under
"Technical data" (Y page 369). G

WARNING
If you uncouple a trailer with an engaged over- run brake, you could trap your hand between
the vehicle and the trailer drawbar. This poses a risk of injury.
Do not uncouple a trailer with an engaged
overrun brake. G
WARNING
Vehicles with level control:
If you disconnect the trailer cable, the vehicle is lowered. This can cause you or others to
become trapped between the vehicle body
and tyres, or underneath the vehicle. This
poses a risk of injury.
Make sure that no-one is in the immediate
vicinity of the wheel arch or underneath the
vehicle when disconnecting the trailer cable.
! Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your vehicle could
be damaged by the rebounding of the overrun
