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
the steerin gwheel is turned.
R if you ar edriving at speeds between
40 km/h and 70 km/h and tur nthe steer-

RNING
Driving safety may be impaired if non-
approved parts ,tyres and wheels or safety-
relevant accessories are used.
This could lead to malfunctions in safety-rel-
evant systems, e.g. the brake system. This
could cause you to lose control of your vehicle
and cause an accident.
For this reason, Mercedes-Benz recommends
that you use genuine Mercedes-Benz parts or
parts of equal quality. Only use tyres, wheels
and accessories that have been specifically
approved for your vehicle. H
Environmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war-
ranty applies as for new parts.

as control units and sensors for these
restraint systems, may be installed in the
following areas of your vehicle:
