Tyre pressure
f Select the vehicle tyre pressure for full load
when towing a trailer.
f The information on tyre pressure is provided in
the chapter Technical Data in this Driver’s
Manual:
Please observe the chapter “TYRE
PRESSURES, COLD” on Page 367.
f Check the tyre pressure of the trailer’s wheels
according to the manufacturer’s instructions.
Door mirrors
f If the width of the trailer obstructs your view of
the traffic behind the trailer, you must have
additional door mirrors fitted.
Headlights, lights
f Always check the headlight adjustment before
driving with a trailer.
If necessary, correct with the headlight beam
adjustment function.
f Check whether the plug of the trailer is
plugged into the towing vehicle and whether all
lights function.
Driving with a trailer
The vehicle with trailer must be used at a speed
appropriate to street and traffic conditions, as well
as adjusted to the loading situation. Never exceed
a speed of 80 km/h (50 mph). Excessive speed
considering the conditions of use can lead to
losing control of the vehicle-trailer combination.
f Carefully and gradually familiarise yourself with
the handling and braking behaviour of the
vehicle-trailer combination.
f Do not drive with the towing vehicle empty and
the trailer loaded.
If this unfavourable condition is unavoidable,
please drive especially slowly.
f Bear in mind the different vehicle handling and
size in situations such as braking, parking,
cornering and overtaking, etc.
f The driving stability of the vehicle-trailer combi-
nation worsens as the speed increases. There-
fore, drive especially slowly on downhill
stretches and in the case of unfavourable road
and weather conditions (such as wind).
f Drive in an appropriately low gear on downhill
stretches in order to make use of the engine
braking effect.
f Slow down immediately if the trailer starts to
sway. Do not countersteer; brake if necessary.
Never attempt to straighten out the vehicle-
trailer combination by accelerating.
f Activate the Low Range off-road driving
programme when moving off on steep slopes.
f Under no circumstances may people, animals
or objects be in the space between the trailer
and towing vehicle when the vehicle is moving.
f When reversing, bear in mind that ParkAssist is
not active.
Maintenance note
f Please take into consideration that driving with
a trailer places much greater stress on all
vehicle components. Expert inspection and
maintenance after every use are indispensable
prerequisites for proper functioning and safety.
