lamps: press button :.
The hazard warning lamps automatically
switch on if:
R an airbag is deployed.
R the vehicle decelerates rapidly from a
speed of more than 70 km/ha nd comes to
a standstill.
The hazard warning lamps switch off auto-
matically if the vehicle reaches a speed of
over 10 km/h again after a full brake appli-
cation.
i The hazard warning lamps still operate if
the ignition is switched off. Headlamp cleaning system
The headlamps are cleaned automatically if
the "Wipe with washe rfluid" function is oper-
ated five times (Y page 135) while the lights
are on and the engine is running. When you
switch off the ignition, the automatic head-
lamp cleaning system is reset and counting is
resumed from 0. Intelligent Light System
General notes The Intelligent Light System is a system that
adjusts the headlamps automatically to suit
the prevailing driving and weathe
rconditions.
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 243). Active light function
The active light function is a system 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 light function improves the illu-
mination of the road over a wide 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:
if you are driving at speeds below
40 km/ha nd switch on the tur nsignal or turn
the steering wheel.
Not active: if you are driving at speeds above
40 km/h or switch off the turn signal or turn
the steering wheel to the straight-ahead posi-
tion. 128
Exterior lightingLights and windscreen wipers

The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes.
Motorway mode Active:
if you are driving at aspeed above
110 km/ hand do not make any large steering
movements for at least 1000 m or if you are
driving at a spee dabove 130 km/h.
Not active: if you are driving at speeds below
80 km/h following activation.
Extended range foglamps The extended range foglamps reduce the
glare experienced by the driver and improve
the illumination of the edge of the carriage-
way.
Active: if you are driving at speeds below
70 km/ hand you switch on the rea rfoglamp.
Not active: if, following activation, you are
driving at speeds above 100 km/h or if you
switch off the rear foglamp. Adaptive Highbeam Assist
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 a sticker
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 lighting is not clearly visi-
ble, e.g. road users behind a crash barrier
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. Exterior lighting

You can use this function to set the head-
lamps to change betwee
ndipped beam and
main beam automatically. The system recog-
nises vehicles with their lights on, either
approaching fro mthe 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 headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the main-beam headlamps.
The system's optical sensor is located behind
the windscreen near the overhead control
panel. Switching Adaptive Highbeam Assist

The _ indicator lamp in the multifunc-
tion display lights up if it is dark and the
light sensor activates the dipped-beam
headlamps.
If you are driving at speeds above
45 km/h:
the headlamp range is set automatically
depending on the distance between the
vehicle and other road users.
If you are driving at speeds above
55 km/h and no other road users are rec-
ognised:
the main-beam headlamps are switched on
automatically .The K indicator lamp in
the instrumentc luster also lights up.
If you are driving at speeds below
45 km/h or other road users are recog-
nised or the roads are adequately lit:

Keep bulbs out of the reach of children. Oth-
erwise, they could damage the bulbs, for
example, and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may break or even explode and
injure you.
Halogen bulbs are pressurised and can
explode when you change them, particularly
if they are very hot. You should therefore wear
eye protection and gloves when you are
changing them.
There are bulbs other than the xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y page 133). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance changing bulbs, con-
sult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint-
free cloth or only touch the base of the bulb
when fitting.
Only use bulbs of the correct type.
If the new bulb still does not lightu p, consult
a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly. Overview of bulb replacement

You can replace the following bulbs. The
details for the bulb type can be found in the
