Instrument and switch lighting 1
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. 74 1
.
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 lamps (“xenon lamps”) 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.

ing using adaptive head-
lights 

Lights and visibility
Dynamic cornering lights* (AFS)
The dynamic cornering lights only operate if the vehicle is travelling at more
than 10 km/h (6 mph) 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 lamp  lights up on the instrument panel but all the bulbs are
operating correctly ⇒ page 272, 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
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 light automatically comes on to function as a cornering light. The
cornering light only operates if the dipped beam 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”
is merely a system to support the driver. Where necessary, switch on the
lights manually using the light switch.

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

Turn signal and main beam headlight lever
The turn signal and main beam lever also operates the park-
ing lights and the headlight flasher.
Fig. 77 Turn signal and
main beam headlight lev-
er
The turn signal and main beam headlight lever has the following
functions:
Switching on the turn signals
– Move the lever all the way up ⇒ Fig. 77 1
to indicate right, and
all the way down 2 to indicate left.
Signalling a lane change
– Push the lever up 1
or down 2 to the point where you incur
resistance and then release it. The turn signal will flash several
times. The corresponding control lamp will also flash. Switching main beam on and off
–
If the dipped lights are on, push the lever forward ⇒ Fig. 77 3
to switch on the main beam.
– Push the lever towards the steering wheel ⇒ Fig. 77 4
to
switch off the main beam.
Headlight flashers
– Pull the lever towards the steering wheel 4
to operate the
flasher.
Switching on parking lights
– Switch the ignition off and remove the key from the lock.
– Move the turn signal lever up or down to turn the right or left-
hand parking lights on, respectively.
WARNING
The main beam can dazzle other drivers. Risk of accident! Never use the
main beam headlights or the headlight flasher if they could dazzle other
drivers.
Note
● The turn signals only work when the ignition is switched on. The corre-
sponding warning lamp  or  flashes in the instrument panel. The control
lamp  flashes when the turn signals are operated, provided a trailer is
correctly attached and connected to the vehicle. If a turn signal bulb is de-
fective, the control lamp flashes at double speed. If the trailer turn signal
bulbs are damaged, control lamp  does not light up. Change the bulb.
● The main beam headlights can only be switched on if the dipped beam
headlights are already on. The warning lamp  then comes on in the instru-
ment panel. 

Bulb change General notes
Before changing any bulb, first turn off the failed component.
Do not touch the glass part of the bulb with your bare hands. The finger-
prints left on the glass will vaporise as a result of the heat generated by the
bulb, causing a reduction in bulb life and condensation on the mirror sur-
face, thus reducing effectiveness.
A bulb must only be replaced by one of the same type. The type is indicated
on the bulb, either on the glass part or on the base.
It is highly recommended to keep a box of spare bulbs in the vehicle. At the
very least, the following spare bulbs, which are essential for road safety,
should be kept in the vehicle. Main headlights

On this type of headlight, the bulb changes must be made by the Technical Service, given
that complex elements must be removed from the vehicle and a reset must be made on the
automatic control system incorporated.
2) The Xenon bulbs discharge 2.5 times the light flux and have an average lifespan of 5 times
more than that of halogen bulbs, this means that, except due to unusual circumstances,
there is no need to change the bulbs for the whole life of the vehicle.
3) Electronically controlled single filament bulb for Stop/side bulbs. If the bulb blows it will
not work in either position or Stop.

Note
● Depending on weather conditions (cold or wet), the headlights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This
has no influence on the useful life of the lighting system. By switching on
the lights, the area through which the beam of light is projected will quickly
be demisted. However, the edges may continue to be misted.
● Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning properly. This is not only in the inter-
est of your own safety, but also that of all other road users.
● Due to the difficulty in accessing some of the bulbs, any replacement
work should be done by a Technical Service. However, the following is a de-
scription of how to change the lamps except for the fog lights* and interior
lamps. 
