WARNING
If you do not pay attention to the warning lights coming on and the corre-
sponding descriptions and warning notes, this may result in severe body inju-
ries or major vehicle damage.
The engine compartment of your car is a hazardous area. There is a risk of
injuries, scalding, accident s and fire when working in the engine compartment,
e.g. inspecting and replenishing oil and other fluids. It is also essential to
observe all warnings page 216, “Working in the engine compartment”.Note
The arrangement of the indicator lights depends on the model version. The
symbols shown in the following functional description are to be found as indicator
lights in the instrument cluster.
Operational faults are shown in the instrument cluster as red symbols (priority 1 -
danger) or yellow symbols (priority 2 - warning).
Turn signal system
Either the left
or right
indicator light flashes depending on the position of the turn
signal lever.
The indicator light flashes at twice its normal rate if a turn signal light fails.
Switching off the hazard warning light system is switched on will cause all of the turn
signal lights as well as both indicator lights to flash.
Further information about the turn signal system page 66.
Fog lights
The warning light
comes on when the fog lights are operating page 64.
Main beam
The indicator light
comes on when the main beam is selected or also when the
headlight flasher is operated. Further information about the main beam
page 66.
Low beam
The warning light
comes on when low beam is selected page 60.
Rear fog light
The warning light
comes on when the rear fog lights are operating page 65.
Cruise control system*
The warning light
lights up, when operating the speed regulating system.
Bulb failure
The warning light
comes on if a bulb is faulty:
up to 2 seconds after the ignition is switched on,
when switching on the defective light bulb.
The following text e.g will be displayed in the information display*: Check front right dipped beam!
The rear side lights and the licence plate lighting require several light bulbs. The indi-
cator light
only lights up if all light bulbs of the licence plate lighting or the parking
light (in one rear light unit) are defective. Check regularly the function of the light
bulbs.
Adaptive headlights*
If the warning light
flashes for 1 minute while driving or after switching on the igni-
tion and a warning signal sounds, a fault of the adaptive headlights is confirmed.

– Push the main beam lever forward in the spring-tensioned position in order to switch on the main beam page 66, fig. 52 .
Switching off the main beam– If you push the lever towards the steering wheel in direction of arrow (spring-
tensioned position) page 66, fig. 52, the main beam is switched off.Switching off lights (except daylight driving lights)– Turn the light switch into position°0.
When the parking lights are switched on, the symbol
next to the light switch is illu-
minated. Low beam comes on only if the ignition is switched on. After switching off the ignition,
the low beam is switched off automatica
lly and only the side lights come on.
On models fitted with right-hand steering the position of certain switches differs
from that shown in fig. 46 . The symbols which mark the switch positions are iden-
tical, however.
WARNING
Never drive with side lights on - risk of accident! The side lights are not bright
enough to light up the road sufficiently in front of you or to be seen by other
oncoming traffic. In this case, always switch on the low beam when it is dark or
if visibility is poor.
Note
An audible warning will sound if you wi thdraw the ignition key and open the
driver's door when the vehicle lights are still on.
The acoustic warning signal is switched off over the door contact when the driver's
door is closed (ignition off). The vehicle can be parked with the side lights on.
If the car is parked for a lengthy period, we recommend switching off all lights, or
leaving only the parking lights switched on.
The switching on of the described lights should only be undertaken in accordance
with the legal requirements.
If a fault occurs in the light switch , the low beam comes on automatically
In the event of cool or humid weather conditions, the headlights can be misted up
from inside.
The temperature difference between interior and external area of the headlight
lenses is decisive.
When the driving lights are switched on, the light outlet surfaces are free from
mist after a short period. The headlight lens es can possibly mist up at the border
areas.
It also concerns reverse light and turn signal lights.
This mist has no influence on th e life of the lighting system.

sensor, the symbol illuminates additionally next to the light switch.
If the light comes on automatically, the side lights and low beam as well as licence plate
light light up at the same time.
If the automatic light control is switched on, the light is regulated with the light sensor
in the rear mirror holder. If the light intensity drops below the set value, e.g when
driving during the day into a tunnel, the low beam and the side lights as well as the
licence plate light come on automatically. If the light intensity increases again, the
lights switch off automatically.

WARNING
The automatic light control only operat es as a support. The driver is not
released from his responsibility to inspect the light and if necessary to switch on
the light depending on the light conditions. The light sensor cannot detect for
example rain or snow. For these conditions we recommend to switch on the low
beam
!
Note
Do not affix any stickers in front of the light sensor, so that you do not impair its
function or put it out of operation.
The same principles as for using the automa tic light control also apply to the light

Adaptive headlights (AHL)*Switch on Adaptive headlights (AHL)*– Turn the light switch page 61, fig. 47 into position
.
The AHL system* is activated if:
the light sensor recognizes the low light intensity,
no reverse gear is engaged,
the operation “tourist light” is not switched on.
The light sensor switches on the full outer illumination at low light intensity.
System AHL* makes it possible to change th e length and width of illumination of the
headlight. The length and width of illuminati on changes automatically in relation to the
vehicle speed and the use of the windscreen wiper.
System AHL* operates in the following modes.
Mode out of town
The mode “out of town” is a basic mode. The di spersion of the cone of light in front of
the vehicle is similar to the low beam. The mode is active if none of the following
modes are active.
Mode rain
In the mode “rain” the dispersion of the cone of light in front of the vehicle is wider and
the width of illumination is shorter, so th at during bad weather (rain) the dazzling of
the oncoming drivers can be reduced. The mode is activated at speeds of 15 - 70 km/h
and if the windscreen wipers continuously operate for a peri od of time longer than 2
minutes. The mode is deactivated when dr opping below or exceeding the set speed
limit or if the windscreen wipers have been switched off for a period of time longer
than 8 minutes.
Mode city
In the mode “city”, the dispersion of the cone of light in front of the vehicle is wider and
the width of illumination is sh orter. It has as an aim to illuminate the adjacent foot-
paths, crossings, pedestrian crossings etc. The mode is active at speeds of 15 - 50 km/h.

Mode motorway
In the mode “motorway” the dispersion of the co ne of light is so widespread, that it illu-
minates also the left (and right)
7) lane of the motorway, so that the driver can react in
time to an obstacle or any other danger. The mode is activated stepwise as of a speed
of 90 km/h. It gains its greatest effectiveness at speeds above 120 km/h.
Tourist light
This mode makes it possible to drive in countries with opposing traffic system, driving
on the left/right, without dazzling the oncoming vehicles. When the mode “tourist
light” is active, the above mentioned modes and the side to side swivel of the headlight
is deactivated.
The mode “tourist light” is activated / deac tivated via the information display* in the

Cornering lights
The cornering lights are used to illuminate the curves by means of the cone of light
swiveling together with the front headlight with Xenon lights*. This function is active
when the speed of the car increases to more than 10km/h.
The swiveling function of the headlights ca n be switched off / on via the menu point
Assistants in the main menu of the information display* page 23.WARNING
If the cornering ligh ts are defective, the headlights are automatically lowered to
the emergency position, whic h prevents a possible dazzling of oncoming traffic.
Thus the illuminated length of the road is shortened. Drive carefully and have
the car inspected immediatel y by a specialist garage.
Note
