Instrument and switch lighting

When the headlights are switched on, the brightness of the instruments
and switch lighting can be regulated to suit your requirements by turning
the thumb wheel 
⇒ fig. 73

.
The instrument lighting (dials and needles), the centre console illumination
and the illumination of the displays are regulated by a photodiode incorpo-
rated in the instrument panel.
The instrument lighting (dials and needles) is switched on when the igni-
tion is on and the 
vehicle lights are off. The instrument lighting is dimmed
automatically as the daylight starts to fade. It goes out completely when the
ambient light level is very low. This function is intended to remind the driver
to switch on the dipped beam headlights in good time when light condi-
tions become poor.
Headlight range control 
2
By using the electrical headlight range control, 
2
 you can adjust the head-
light range to the load level that is being carried in the vehicle. This way, it
is possible to avoid dazzling oncoming traffic more than necessary. At the
same time, by using the correct headlight settings, the driver has the best
possible lighting for the road ahead.
The headlights can only be adjusted when the dipped beam is switched on.
To lower the beam, turn the thumb wheel down 
2
 from the basic setting 
0.
Dynamic headlight range control
Vehicles with 
gas discharge bulbs (“xenon bulbs”) are equipped with dy-
namic headlight range control. This means that the headlights will be ad-
justed to suit the load level of the vehicle and “nodding movements” when
pulling off and braking are automatically compensated for.
Vehicles with gas discharge bulbs do not have headlight range control.

Adaptive headlights* (for driving round bends)
When driving around bends, the headlights will light the
most important areas of the road.

Dynamic cornering lights (AFS)
The 
dynamic cornering lights only operate if the vehicle is travelling at more
than 10 km/h and the dipped headlights are on. When taking a bend, the
road is illuminated better with directional gas discharge bulbs than with
conventional fixed headlights.
A fault in the system is indicated via the flashing of the control lamp  on
the instrument panel. At the same time, a text message with information or
instructions to perform necessary operations may appear on the instrument
panel display. Take the vehicle to a specialised workshop and have the fault
repaired.
If the control bulb  lights up on the instrument panel but all the bulbs are
operating correctly 
⇒ page 254, there may still be a fault in the dynamic
curve lighting system (AFS). Take the vehicle to a specialised workshop and
have the fault repaired.
WARNING_If_the_“automatic_dipped_beam_control”_is_switched_on,_the_dipped_beam_headlights_will_not_be_switched_on_in_fog._They_should_be_switched_on'>WARNING
If the “automatic dipped beam control” is switched on, the dipped beam
headlights will not be switched on in fog. They should be switched on
manually using the light switch. The driver is personally responsible for
the correct use of lights in all situations. “Automatic headlight control”
is merely a system to support the driver. Where necessary, switch on the
lights manually using the light switch.

Fog lights with cornering function*
When the turn signal is switched on to turn or on very tight bends, the right
or left fog lamp automatically comes on to function as a 
cornering light. The
cornering light only operates if the dipped lights are on.
WARNING
If the “automatic dipped beam control” is switched on, the dipped beam
headlights will not be switched on in fog. They should be switched on
manually using the light switch. The driver is personally responsible for
the correct use of lights in all situations. “Automatic headlight control”

Hazard warning lights 
The hazard warning lights are used to draw the attention of
other road users to your vehicle in emergencies.

ing lights
If your vehicle breaks down:

3. Switch the engine off.
4. Apply the handbrake.
5. On a manual gearbox engage 1st gear. On an automatic, move
the selector lever to 
P.
6. Use the warning triangle to draw the attention of other road
users to your vehicle.
7. Always take the vehicle key with you when you leave the vehi-
cle.
Switch on the hazard warning lights to warn other road users, for example
when:
● reaching the tail end of a traffic jam,
● there is an emergency
● your vehicle breaks down due to a technical fault,
● you are towing another vehicle or your vehicle is being towed.
All turn signals flash simultaneously when the hazard warning lights are
switched on. That is that the two turn signal turn signal lamps   and the
turn signal lamp in the switch  will flash at the same time. The hazard
warning lights also work when the ignition is switched off.
Emergency braking warning
If the vehicle is braked suddenly and continuously at a speed of more than
80 km/h, the brake light flashes several times per second to warn vehicles
driving behind. If you continue braking, the hazard warning lights will come
on automatically when the vehicle comes to a standstill. They switch off au-
tomatically when the vehicle starts to move again.
WARNING
●
The risk of an accident increases if your vehicle breaks down. Always
use the hazard warning lights and a warning triangle to draw the atten-
tion of other road users to your stationary vehicle.
●
Never park where the catalytic converter could come into contact with
inflammable materials under the vehicle, for example dry grass or spilt
petrol. This could start a fire!
Note
● The battery will run down if the hazard warning lights are left on for a
long time, even if the ignition is switched off.
● The use of the hazard warning lights described here is subject to the rel-
evant statutory requirements.
