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 60.
Fog lights
The warning light comes on when the fog lights are operating ⇒page 57.
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 60.
Low beam
The warning light comes on when low beam is selected ⇒page 53.
Rear fog light
The warning light comes on when the rear fog lights are operating ⇒ page 58.
Cruise control system*
The warning light lights up, when operating the speed regulating system.
Failure of the light bulbs
The warning light comes on if a light bulb is damaged:
•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
indicator light
only lights up if all light bulbs of the licence plate lighting or the
parking light (in one rear light unit) are defe ctive. 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
ignition and a warning signal sounds, a fault of the adaptive headlights is
confirmed.
Further information ⇒page 56.
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 ou t with the 4th or 5th gear engaged (auto-
matic gearbox: position S) when the traffi c 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 contro l unit shifts the engine into
the emergency mode, which only has a re duced power output. After switching the
ignition off and on again the warning light
comes on.

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 shorter. It has as an aim to illuminate the adjacent
footpaths, 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 cone of light is so widespread, that it
illuminates also the left (and right)
6) 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
When driving in countries with opposing traffic system, driving on the left/right, it is
possible to switch on the mode “tourist light” electronically. This mode makes it
possible to drive in the particular count ry 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 in the information display* in the menu
⇒ page 19:
„SETUP (Settings)
„Automatic light (Automat. Lights)
Note
•The functions of the side to side swivel of the headlight* (activation at a speed
of 10 km/h), fog lights with the function “corner” ⇒page 57 and the function
dynamic headlight beam range* add to the System AHL*.
•The System AHL* is solely delivered with Bi-Xenon gas discharge bulbs for low
beam and main beam lights.
Fog lights
Switching on the fog lights
– First of all turn the light switch into position
or ⇒ fig. 43 .
– Pull the light switch into position .
The rear fog light warning light ⇒ page 26 lights up in the instrument cluster
when the fog light is switched off.
Fog lights with the function “Corner”*
The fog lights with the function “Corner” are designed for a better
illumination of all areas near the vehicle when corning, parking etc.
The fog lights with the function “Corner” are regulated according to the steering
angle or after switching on the turn signal light 7) in the following circumstances:
•the vehicle is stationary and the engine is running or it moves with a speed of
maximum 40 km/h;
•the daylight driving lights are not switched on;
6)It is valid for vehicles which are designed for driving on the left.
7)If both switch on versions are conflicting, for example if the steering wheel is turned to the
left and the right turn signal light is switched on, the turn signal light has the higher priority.

Headlamp range adjustment*
Once the low beam is switched on you can then adapt the range of
the headlights to the load of the vehicle.
– Turn the control dial ⇒fig. 45 until you have adjusted the low beam
so that oncoming traffic is not dazzled.
Settings
The positions correspond approximat ely to the following vehicle loads:
Front seats occupied, luggage compartment empty.
All seats occupied, lugg age compartment empty.
All seats occupied, lugg age compartment laden.
Driver seat occupied, luggage compartment laden.
Caution
Set the headlight beam adjustment in such a way as to avoid dazzling oncoming
traffic.
Note
The Bi-Xenon bulbs* adapt automatically to the load and driving state of the vehicle
(e.g. speed, accelerating, braking) when the ignition is switched on and when driving. Vehicles which are not equipped
with Bi-Xenon bulbs* do not have a
manual headlight rang e adjustment control.
Switch for hazard warning lights
–Press switch ⇒ fig. 46 to switch the hazard warning light system on
or off.
All the turn signal lights on the vehicle flash at the same time when the hazard
warning light system is switched on. The indicator light for the turn signals and the
indicator light in the switch also flash at the same time. You can also switch on the
hazard warning light system if the ignition is switched off.
The hazard warning light system is switched on automatically if an airbag is
deployed in the event of an accident.
Please comply with any legal requirements when using the hazard warning light
system.
Note
Switch on the hazard warning light system if, for example:
•you encounter traffic congestion,
•your vehicle breaks down or an emergency situation occurs.

versions. You can determine which vers ion your vehicle is fitted with
after removing the fuse cover at the location of the fuses.
For particular model versions, the battery must be removed before
removing the fuse cover ⇒page 216.
Removing fuse cover
– Move the circlips ⇒fig. 213 as far as the stop, the symbol
appears behind the circlip and remove the cover.
Installing fuse cover
– Position the fuse cover on the fuse box and push the circlips as far as the stop - the symbol
is visible behind the circlip.
Caution
•When unlocking and locking the fuse cover, it must be pressed on the sides to
the box, otherwise damage can occur to the locking mechanism.
•Carefully position the fuse cover in the engine compartment. If the cover was
not correctly positioned, water can get into the fuses and this results in a damage
to the vehicle!
