Malfunctions
The following conditions may prevent the main beam headlight control from
turning off the headlights in time or from turning off altogether:
● In poorly lit towns with highly reflective signs.
● Other insufficiently lit road users (such as pedestrians or cyclists).
● On tight bends and steep slopes (bumps) and when oncoming vehicles
are partially obscured.
● When the drivers of other oncoming vehicles (such as a truck) can see
over a guard rail in the centre of the road.
● If the camera is damaged or the power supply is cut off.
● In fog, snow and heavy rain.
● With dust and sand turbulence.
● With loose gravel in the field of vision of the camera.
● When the field of vision of the camera is misted up, dirty or covered by
stickers, snow, ice...
WARNING
The convenience features of the main beam assist should not encourage
the taking of risks. The system is not a replacement for driver concentra-
tion.
● You are always in control of the main beam and adapting it to the
light, visibility and traffic conditions.
● It is possible that the main beam headlight control does not recog-
nise all driving situations and is limited under certain circumstances.
● When the field of vision of the camera is dirty, covered or damaged,
operation of the main beam control may be affected. This also applies
when changes are made to the vehicle lighting system, for example, if
additional headlights are installed.
CAUTION
To avoid affecting the operation of the system, take the following points in-
to consideration:
● Clean the field of vision of the camera regularly and make sure it is free
of snow and ice.
● Do not cover the field of vision of the camera.
● Check that the windscreen is not damaged in the area of the field of vi-
sion of the camera.
Note
Main beam and headlight flasher can be turned on and off manually at any
time with the turn signal and main beam lever ⇒ page 107. 
Adjusting the headlights
The light beam of the dipped beam lights is asymmetric: the side of the
road on which you are driving is lit more intensely. 

Windscreen wiper functions
Windscreen wiper performance in different situations:If the vehicle is at a stand-
still:The activated position provisionally changes
to the previous position.
During the automatic wipe:
The air conditioner comes on for approxi-
mately 30 seconds in air recirculation mode
to prevent the smell of the windscreen wash-
er fluid entering the inside the vehicle.
For the interval wipe:The intervals between wipes vary according
to the speed of the vehicle. The higher the
vehicle speed the shorter the intervals.
Heated windscreen washer jets
The heating only thaws the frozen jets, it does not thaw the water in the
washer hoses. The heated windscreen washer jets automatically adjust the
heat depending on the ambient temperature, when the ignition is switched
on.
Headlight wash/wipe system
The headlight washers/wipers clean the headlight lenses.
After the ignition is switched on, the first and every fifth time the wind-
screen washer is switched on, the headlights are also washed. Therefore,
the windscreen wiper lever should be pulled towards the steering wheel
when the dipped beam or main beam are on. Any incrusted dirt (such as in-
sects) should be cleaned regularly (e.g. when refuelling).
To ensure the headlight washers work correctly in winter, any snow which
has got into the bumper jet supports should be cleaned away. If necessary,
remove snow with an anti-icing spray.
Note
The wiper will try to wipe away any obstacles that are on the windscreen.
The wiper will stop moving if the obstacle blocks its path. Remove the ob-
stacle and switch the wiper back on again. 
Windscreen wipers service position
