Exterior lightingLights and windscreen wipers

Active ligh
tfunction 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 remai nilluminated 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 tigh
tbends, for example. The corner-
ing light function can only be activated when
the dipped-beam headlamps are switched on.
Active:
R if you are driving at speeds below
40 km/h and switch on the turn signal or
turn the steering wheel.
R if you are driving at speeds between
40 km/h and 70 km/h and turn the steer-
ing 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.
The cornering light function may remain lit for
a short time, but is automatically switched off
after no more than three minutes.
Motorway mode Motorway mode increases the range of the
beam.
Active:
R
if you are driving at speeds above
110 km/ha nd do not make any large steer-
ing movements for 1000 m
R if you are driving at speeds above
130 km/h
Not active: if you are driving at speeds below
80 km/h following activation.

the illumination of the edge of the carriage-
way.
Active: if you are driving at speeds below
70 km/h and yo uswitch on the rear foglamp
Not active: if you are driving at speeds above
10 0k m/h or if you switch off the rear foglamp
following activation Adaptive Highbeam Assist
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, visio nand 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 windscree naround 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.
You can use this function to set the head-
lamps to change between dipped beama ndmain beam automatically. The system recog-
nises vehicles with thei
rlights 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. X
To activate: activate the Adaptive High-
beam Assist function using the on-board
computer (Y page 202).
X Turn the light switch to Ã.
X Press the combination switch beyond the
pressure point in the direction of
arrow :(Ypage 98).
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: Exterior lighting
101Lights and windscreen wipers Z

the headlamp range is se
tautomatically
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 Kindicator lamp in
the instrumen tcluster 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:
the main-beam headlamps are switched off
automatically. The Kindicator lamp in
the instrumen tcluster goes out. The _
indicator lamp in the multifunction display
remains lit.
X To deactivate: move the combination
switch back to its normal position.
The _ indicator lamp in the multifunc-
tion display goes out. Headlamps misted up on the inside
The headlamps may mist up on the inside if
there is high atmospheric humidity.
X Drive with the headlamps switched on.
The level of moisture diminishes, depend-
ing on the length of the journey and the
weathe rconditions (humidity and temper-
ature).
If the level of moisture does not diminish:
X Have the headlamps checked at a qualified
specialist workshop. Interior lighting

Never use a bulb which has been dropped.
Such a bulb may break or even explode and
injure you.
Halogenb ulbs 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 104). 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 correc ttype.
If the new bulb still does no tlight up, consult
a qualified specialist workshop.
Bulbs and lamps are an importan taspect 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
