visually and acoustically. If you do not brake

(Y page 40). If the risk of collision persist sand

In particular, the detection of obstacles can
be impaired if ther eis:
R dirt on the sensors or the sensors are cov-

Depending on the curren tspeed, PRE-SAFE ®
Brak edecelerates your vehicle by up to
4m /s2

upper body of the occupants. The belt strap
is tightened slightly when:
R you engage the belt tongue in the buckle
and then turn the key to position 2in the

and you then engage the belt tongue in the
buckle once the seat-belt extender has

The seat-belt adjustment will apply acertain
tightening force if any slack is detected
between the occupant and the belt sash. The
belt should not be held during the adjust-
ment.Y ou can switch the belt adjustment on

The 0082 seat belt warning lamp in the instru-
ment cluster reminds you that all occupants
should fasten their seat belts. It is either lit
continuously or flashes. Additionally, there
may be awarning tone.
The 0082 seat belt warning lamp goes out and
the warning tone ceases as soon as the driver
and front passenger have fastened their seat
belts.
For certain countries only: regardless of
whether the driver or the front passenger
already have their seat belt fastened, the
0082 seat belt warning lamp lights up for six
seconds after the engine has been started. It
then goes out if both the driver and the front
passenger have fastened their seat belt. i

belt warning lamp (Y page 236). Rear seat belt status indicator
The rear-compartment seat belt status indi-
cator tells you if the rear passengers have
their seat belts fastened. It indicates the rear
seat on which the belt is fastened.
The rear-compartment seat belt status indi-
cator appears in the multi-function display for
around 30 seconds if
R you set off and have reached aspeed of
approximately 10 km/h.
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in

asystem which
adjusts the headlamps automatically to suit
the prevailing driving and weather conditions.
The bi-xenon headlamps offer enhanced func-
tions to improve illumination of the road sur-
face, 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 fog-
lamps. The system is only active when it is
dark.
You can activat eordeactivate the "Intelligent
Light System" using the on-board computer
(Y page 119). Active light function
The active light function is
asystem that
moves the headlamps accordin gtothe steer-
ing movements of the frontw heels. In this
way, relevant areas remain illuminated while
driving. This allows you to recognise pedes-
trians, cyclists and animals.
Cornering light function The cornering light function 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 driving at speeds below
40 km/h, the cornering light function is
activated either by the turn signal or by the
steerin gwheel being turned.
R if you are driving at speeds between
40 km/ha nd 70 km/h ,the cornerin glight
function is activated by th esteering wheel
