The main beam can dazzle other drivers. Risk
of ac c
ident! Never use the main beam head-
lights or the headlight flasher if they could
dazzle other drivers. Note
● If the c on
venience turn signals are operat-
ing (three flashes) and the other convenience
turn signals are switched on, the active part
stops flashing and only flashes once in the
new part selected.
● The turn signals only
work when the igni-
tion is switched on. The corresponding warn-
ing 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 vehi-
cle. If a turn signal bulb is defective, the con- trol lamp flashes at double speed. If the trail-
er turn s
ign
al bulbs are defective, the control
lamp does not light up. Change the bulb.
● The main beam headligh
ts can only be

Lights and visibility
Fog lights with cornering function* This is an additional light source to dipped
beam he
a
dlights to light up the road as a
bend is taken.
The cornering light operates with the lights
switched on and when driving at less than
40 Km/h (25 mph). Ignition occurs by turning
the steering or connecting the turn signal.
Forward gear
● If the steering wheel is turned to the right,
or the right-h and t
urn signal operated, the
right-hand fog light turns on.
● If the steering wheel is turned to the left, or
the left
-hand turn signal operated, the left-
hand fog light turns on.
In reverse, both fog lights turn on. Note
When the fog lamps are on, the cornering

The instrument lighting (some dials and nee-
dles), the centre console lighting and the
lighting of the displays are regulated by a
photodiode incorporated in the instrument
panel.
The instrument lighting (needles) is switched
on when the ignition is on and the light is
off. The instrument lighting is dimmed auto-
matically as the daylight starts to fade. It
goes out completely when ambient light 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 bec
ome poor.
Headlight range control
By using the electrical headlight range con-
trol you can adjust the headlight range to the
load level that is being carried in the vehicle
››› Fig. 127. This way, it is possible to avoid
dazzling oncoming traffic more than necessa-
ry. 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. Turn the
wheel downwards to lower the headlight
beam from the basic setting 0.
Dynamic headlight range control
Vehicles with gas discharge bulbs (xenon
bulbs) are equipped with dynamic headlight
range control. When you switch on the lights,
their range regulates itself according to the
vehicle load.
Vehicles with gas discharge bulbs do not
have headlight range control.
