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:

Coupling up a trailer
X Apply the electric parking brake manually.
X Shift the transmission to position P.
X Position the trailer on a level surface behind
the vehicle.
X Couple up the trailer.
X Establish the electrical connection between
the vehicle and the trailer.
X Check that the trailer lighting system is work-
ing.
X Push the combination switch upwards and
downwards and check whether the corre-
sponding turn signal indicator on the trailer is
flashing.
A connected trailer is only detected when the
electrical connection is established correctly
and the lighting system is working properly. The
function of other systems also depends on this, for example:
R ESP ®
R PARKTRONIC
R Active Parking Assist
R Active Blind Spot Assist
R Active Lane Keeping Assist Uncoupling a trailer
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
brake.
! Remove the adapter cable before folding in
the ball coupling. You could otherwise dam-
age the rear bumper and the adapter cable.
X Apply the electric parking brake manually.
X Shift the transmission to position P.
X Switch off the engine.
X Secure the vehicle and trailer against rolling
away.
X Remove the trailer cable and uncouple the
trailer. Trailer power supply
