The hazard warning lamps switch on auto-
matically if:
R an airbag is deployed 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 auto-
matically if the vehicle reaches a speed of
above 10 km/ha gain after a full brake appli-
cation.
i The hazard warning lamps continue to
operate even if the ignition is switched off. Headlamp cleaning system
The headlamps are cleaned automatically if
the "Wipe with washer fluid" function is oper-
ated five times (Y page 133) 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 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 253). 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:
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/ha nd 70 km/h and turn the steer-
ing wheel Exterior lighting
127Lights andwindscreen wipers Z
Not active:
if you are driving at speeds above
70 km/h or switch off the turn signal or turn
the steering wheel to the straight-ahead posi- tion.
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 a speed above
110 km/h and do not make any large steering movements for at least 1,000 mor 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 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/h and you switch on the rear foglamp. 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
General notes You can use this function to set the head-
lamps to change between dipped beam and
main beam automatically. The system recog-
nises vehicles with their lights on, either
approaching from the 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
switches on the main-beam headlamps again.
The system's optical sensor is located behind
the windscreen near the overhead control
panel. 128

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
In very rare cases, Adaptive Highbeam Assist
recognises road users too late or not at all. In
this, or in similar situations, the automatic
main-beam headlamps will not be deactivated
or activated regardless. There is a risk of an
accident.
Always carefully observe the traffic conditions and 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 conditions.
In particular, the detection of obstacles can
be restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or if the sensors are
obscured

vehicle and other road users.
If you are driving at speeds above approx-

are detected:
The main-beam headlamps are switched on
automatically. The Kindicator lamp in
the instrument cluster also lights up.
If you are driving at speeds below 45 km/h
or other road users are detected or the
roads are adequately lit:
The main-beam headlamps are switched off automatically. The Kindicator lamp in
the instrument cluster goes out. The _

Only operate bulbs in enclosed lamps
designed for that purpose. Only fit spare
bulbs of the same type and the specified volt- age.
Marks on the glass tube reduce the service
life of the bulbs. Do not touch the glass tube
with your bare hands. If necessary, clean the
glass tube when cold with alcohol or spirit and
rub it off with a lint-free cloth.
Protect bulbs from moisture during opera-
tion. Do not allow bulbs to come into contact
with liquids.
You can neither replace xenon bulbs nor LED bulbs. Have LED bulbs replaced at a qualified
specialist workshop.
Replace only the bulbs listed (Y page 132).
Have the bulbs that you cannot replace your-
self replaced at a qualified specialist work-
shop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, 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 – bulbs

e.g. sitting, squatting or lying In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road.
Night View Assist Plus camera :picks up the
infrared light and displays a monochrome
image in COMAND. The image displayed in
COMAND corresponds to a road lit up by
main-beam headlamps. This enables you to
see the road's course and any obstacles in
good time. When pedestrian recognition is
active, pedestrians recognised by the system are highlighted in the Night View Assist Plus
display.
Light from the headlamps of oncoming vehi-
cles does not affect the Night View Assist Plus
display in the multifunction display. This is
also the case if you cannot switch on the
main-beam headlamps due to oncoming traf-
fic.
i Infrared light is not visible to the human
eye and therefore does not dazzle. Night
View Assist Plus can therefore remain
switched on even if there is oncoming traf-
fic. Activating Night View Assist Plus Activation conditions
