Technical Data
Fog lights*
The warning light
comes on when the fog lights are operating page 54.
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 57.
Low beam
The warning light
comes on when low beam is selected page 51.
Rear fog light
The warning light
comes on when the rear fog lights are operating page 55.
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 li ghting 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.
Diesel particle filter*
(diesel engine)
If the warning light
comes on, this means that soot has accumulated in the diesel
particle filter because of the frequent short distances.
In order to clean the diesel particle filter, the vehicle should be driven at an even speed
of at least 60 km/h at engine speeds of 1 800 - 2 500 rpm for at least 15 minutes or until
the warning light goes out with the 4th or 5th gear engaged (automatic gearbox: posi-
tion S) when the traffic situation permits it. This increases the exhaust temperature and
the soot deposited in the diesel particle filter is burnt.
Always pay attention to the valid speed limits .
The warning light
goes out after the successful cleaning of the diesel particle filter.
If the filter is not properly cleaned, the warning light
does not go out and the
warning light
begins to flash. In the information display* appears Diesel-particle:
Owner's manual . Afterwards the engine control unit shifts the engine into the emer-
gency mode, which only has a reduced power output. After switching the ignition off
and on again the warning light
comes on.
Have the vehicle inspected without delay by your specialist garage.
WARNING
If you do not pay attention to the warning light coming on and the corre-
sponding descriptions and warning notes, this may result in injuries or major
vehicle damage.
Always adjust your speed to suit weather, road, region and traffic condi-
tions. The route indicated by the warnin g light must not tempt you to disregard
the national regulations for road traffic.Caution
As long as the warning light
li ghts up, one must take into account an incre as ed f uel
consumption and in certain circumstan ces a power reduction of the engine.
Note

Switching on side lights– Turn the light switch into position
.
Switching on the low beam and main beam– Turn the light switch into position
.
– Press the main beam lever forward in order to switch on the main beam page 57, fig. 43 .
Switching off lights (except daylight driving lights)– Turn the light switch into position°0.
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 vehicles with separate ligh ts* for daylight driving lights in the fog lights or in the
front bumper, the low beam does not light up when the light switch is in position 0
even if the ignition is switched on. On models fitted with
right-hand steering the position of certain switches differs
from that shown in fig. 37 . 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 cond itions, 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 lenses 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.

Lights & Vision
On vehicles with separate ligh ts* for daylight driving lights in the fog lights or in the
front bumper, the parking lights and the lice nce plate light do not come on when acti-
vating the function daylight drivin g lights (neither front nor rear).
If the vehicle is not equipped with separate lights* for daylight driving lights, the
combination of the low beam, the parking ligh ts (front and rear) including the licence
plate light is used as daylight driving lights.
In some countries, the na tional legal provisions require that the rear parking lights also
come on together with the separate lights* for daylight driving lights when activating
the function daylight driving lights.
When the daylight driving lights are switch ed on, the illumination of the instrument
cluster is switched off, however, it is switched on in the position
when it is dark
and the low beam shines with full br ightness (100% of the performance).
Automatic driving lamp control*Switching on automatic driving lamp control*– Turn the light switch fig. 38 into position
.
Switching off automatic driving lamp control*– Turn the light switch to the position 0,
or .
If the light switch is in the position
, the symbol illuminates when the ignition is
switched on
next to the light switch. If the low beam is activated with the light
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 lo w 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.
Motorway lights
If the automatic light control* has been swit ched on and the vehicle speed is over 140
km/h for at least 10 seconds, the side ligh ts and low beam are switched on automati-
cally.
If the vehicle speed is below 65 km/h for at least 2 minutes, the lights are switched off.

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
which is switched on manually page 51.
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, which 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.
