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. 56 1.
Vehicles fitted with xenon gas discharge headlights are fitted with an auto-
matic headlight range system.
The instrument lighting (some dials and needles), the centre console light-
ing and the lighting of the displays are regulated by a photodiode incorpo-
rated 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 automatically as the day-
light 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 dip-
ped beam headlights in good time when light conditions 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 dynamic
headlight range control. When you switch on the lights, their range regu-
lates itself according to the vehicle load.
Vehicles with gas discharge bulbs do not have headlight range control.
Daytime driving lights*
Daytime driving lights light up automatically when the igni-
tion is switched on (only with AFS headlights)
Daylight driving lights switch off automatically when the side lights are
switched on.
Activating daytime lights (bi-xenon lamps)
Remove the key from the ignition, move the turn signal lever upwards (right
turn signal), press it backwards to flash position and hold in this position.
Insert the key and switch the ignition on, holding it in this position for 3
seconds. Then, switch off the ignition. The daytime lights are activated and
can be switched on.
Switching daytime lights off (bi-xenon lamps)
Remove the key from the ignition, move the turn signal lever upwards (left
turn signal), press it backwards to flash position and hold in this position.
