To switch the hazard warning lamps on or
off: press the :button.
All the indicator lamps will flash when the
hazard warning lamps are switched on. If you
now switch on an indicator lamp using the
combination switch, only the indicator lamp
on the corresponding side of the vehicle will
flash.
The hazard warning lamps switch on automati-
cally if:
R an airbag has been triggered or
R the vehicle decelerates rapidly from a speed
of above 70 km/h and comes to a standstill
The hazard warning lamps switch off automati-
cally if the vehicle reaches a speed of above
10 km/h again after a full brake application.
The hazard warning lamps continue to operate
even if the ignition is switched off. Intelligent Light System
General notes The Intelligent Light System is a system that
adjusts the headlamps to suit the prevailing
driving and weather conditions. It offers
advanced functions for improved illumination 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
fog lamps. The system is active only when it is
dark.
You can activate/deactivate the Intelligent
Intelligent
Light System Light System function 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 steering move-
ments of the front wheels. In this way, relevant
areas remain illuminated while you are driving.
This allows you to recognise pedestrians,
cyclists and animals sooner.
Active: when the lights are switched on.
Vehicles with Lane Keeping Assist: the active
light function evaluates the course of the lane in which you are driving and adjusts the light in
advance. 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 visi-
bility in tight bends, for example. It can be acti-
vated only 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 steer-
ing wheel
R if you are driving at speeds between 40 km/h
and 70 km/h and turn the steering wheel
The cornering light function may remain lit for a short time, but is automatically switched off
after no more than three minutes.
Cornering light function with roundabout
function:
The cornering light function is activated on both
sides before entering a roundabout through an
evaluation of the current GPS position of the
vehicle. It remains active until after the vehicle
has left the roundabout. In this way, pedestrians crossing the road, for example, are illuminated
by your vehicle in good time.
Only vehicles with the COMAND multimedia sys-
tem have this function.
Motorway mode Motorway mode increases the range of the
beam.
Active:if you are driving at a speed above
110 km/h and do not make any large steering
movements for at least 1000 m or if you are
driving at a speed above 130 km/h.
Not active: if you are driving at speeds below
80 km/h following activation.
Extended range fog lamps The extended-range fog lamps reduce the glare
experienced by the driver and improve the illu-
mination of the edge of the carriageway.
Active: if you are driving at speeds below
70 km/h and you switch on the rear fog lamp.
Not active: if, following activation, you are driv-
ing at speeds above 100 km/h or if you switch
off the rear fog lamp. 118

Adaptive Highbeam Assist
General notes You can use this function to set the headlamps
to switch automatically between dipped beam
and main beam. The system recognises vehicles
with their lights on, either approaching from the opposite direction or travelling in front of your
vehicle, and consequently switches the head-
lamps 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 switches on
the main-beam headlamps again.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.
Important safety notes G
WARNING
Adaptive Highbeam Assist does not recognise road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognise other road users
that have lights, or may recognise them too
late. In this, or in similar situations, the auto-
matic main-beam headlamps will not be deac-
tivated or will be activated despite the pres-
ence of other road users. There is a risk of an accident.
Always carefully observe the traffic conditionsand switch off the main-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You are
responsible for adjusting the vehicle's lighting
to the prevailing light, visibility and traffic con-
ditions. In particular, the detection of obstacles can be
impaired in the case of:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or obscured sensors

If you are driving at speeds above approx-
imately 25 km/h:
The headlamp range is set automatically
depending on the distance between the vehi- cle and other road users.
If you are driving at speeds above approx-
imately 30 km/h and no other road users are
detected:
The main-beam headlamps are switched on
automatically. The Kindicator lamp on the
instrument cluster also lights up.
If you are driving at speeds below 25 km/h or

General notes With Adaptive Highbeam Assist Plus, you can
automatically switch between dipped-beam,
partial main-beam and main-beam headlamps.
Partial main-beam illumination is a form of illu-
mination whereby the main beam is directed Exterior lighting
119Lights and windscreen wipers Z

past other road users. Other road users are kept
out of the main beam. This prevents glare. If
there is a vehicle in front, for example, the main- beam headlamps illuminate the areas to its right
and left, and the vehicle in front is illuminated by the dipped-beam headlamps.
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 switches on
the main-beam headlamps again.
If the main-beam or partial main-beam head-
lamps are causing too much reflection from traf- fic signs, the lights are automatically dimmed
and glare for the driver caused by the reflectionsis thus avoided.
The system's optical sensor is located behind
the windscreen near the overhead control
panel.

Switching the windscreen wipers on/
off
! Do not operate the windscreen wipers when
the windscreen is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windscreen can scratch the
glass if wiping takes place when the wind-
screen is dry.
If it is necessary to switch on the windscreen wipers in dry weather conditions, always
operate them using washer fluid.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may be
due to wax or other residue. Clean the wind-
screen with washer fluid after an automatic
car wash.
! Intermittent wiping with rain sensor: due to
optical influences and the windscreen becom-
ing dirty in dry weather conditions, the wind-
screen wipers may be activated inadvertently. This could damage the windscreen wiper
blades or scratch the windscreen. Windscreen wipers
