tem
General notes Th
eI ntelligent Light System is asystem that
adjusts the headlamps automatically to suit
the prevailing drivin gand weather conditions.
It offers advanced functions for improved illu-
mination of the road surface, e.g. depending
on the vehicle speed or weather conditions.
The system includes the active light function,
cornering light function, motorway mode and
extended range foglamps. The system is only
active when it is dark.
You can activate or deactivate the "Intelligent
Light System" using the on-board computer
(Y page 281). Active light function
The active light function is
asystem that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas remain illuminated while
driving. This allows you to recognise pedes-
trians, cyclists and animals.
Active: when the lights are switched on.
Cornering light function The cornering ligh
tfunction improves the illu-
mination of the road over awide angle in the
direction you are turning, enabling better vis-
ibility in tight bends, for example. It can only
be activated when the dipped-beam head-
lamps are switched on.
Active:
R if you are drivin gatspeeds below
40 km/ hand the turn si gnal is activatedor

st
Important safety notes G
WARNING
Adaptive Highbeam Assist is only an aid
designed to assist driving. The driver is
responsible for adjusting the vehicle's lighting
to the prevailing light, vision and traffic con-
ditions.
The system may be impaired or deactivated:
R if there is poor visibility, e.g. due to snow,
rain, fog or spray
R if the area of the windscreen around the
optical sensor is dirty, misted up or covered
up, e.g. by asticker 124
Exterior lightingLights and windscree
nwipers

The system may not recognise the following
road users:
R road users that have no lighting, e.g. pedes-
trians
R road users that have poor lighting, e.g.
cyclists
R road users whose lightin gisnot clearly visi-
ble, e.g. road users behind acras hb arrier
R on rare occasions: road users that have
lights that may be recognised too late or not
at all
The automatic main-beam headlamps will not
be deactivated, or they may be activated
despite road users travelling in front of or
approaching the vehicle.
Thus, you could cause an accident and injure
yourself and others. Always observe traffic
conditions and, if necessary, dip the lights
manually. You can use this function to set the head-
lamps to change between dippe dbeam and
mai nbeam automatically. The system recog-
nises vehicles with their lights on, either
approaching from the opposite direction or
travelling in front of your vehicle, and conse-
quently switches the headlamps from main
beam to dipped beam.
The system automatically adapts the dipped-
beam headlam prange depending on the dis- tanc
etot he other vehicle. Onc ethe system
no longer detec tsany other vehicles, it reac-
tivates the main-beam headlamps.
The system's optical senso risl ocated behind

panel.
