Important safety notes 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. 236
Towing a trailerDriving and parking

Vehicles with the AIRMATIC package
!
Before beginning the journey, make sure
that the trailer support wheel is completely
raised. Otherwise, the trailer or the vehicle
could be damaged by the lowered trailer sup- port wheel during the journey.
X Shift the transmission to position P.
X Apply the electric parking brake.
X Start the engine.
X Vehicles with the Off-Road Engineering
package:
set the vehicle level to normal level
(Y page 192).
X Vehicles without the Off-Road Engineer-
ing package: select theComfortdrive pro-
gram using the DYNAMIC SELECT controller
(Y page 197).
X Switch off the engine.
X Close the doors and tailgate.
X Position the trailer horizontally 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 when the lighting system is working prop-
erly. The function of other systems also depends on this, for example:
R ESP ®
R Parking Assist PARKTRONIC
R Parking Pilot
R Active Blind Spot Assist
R Active Lane Keeping Assist
i Vehicles with the AIRMATIC package:
if
you couple up a trailer, the vehicle initially
remains at the selected level of the drive pro- gram set. Observe the following when cou-
pling up a trailer:
R If the normal level was not selected previ-
ously, the vehicle automatically adopts the normal level starting from a speed of 30 km/h. Even at higher speeds, it does not
drop below the normal level.
R Vehicle levels below the normal level are
not available.
R The raised level is available up to a speed of
30 km/h.
R This also applies when using accessories
that are plugged into the socket of the
trailer tow hitch (e.g. a bicycle rack).
R Before driving with a trailer, please observe
the information on the trailer support
wheel. Uncoupling a trailer
