tion will illuminate the vehicle and its surroundings by switching on
the dipped headlights, rear lights, engine compartment lighting*
and number plate lights when the driver's door is opened.
The dipped headlights will stay on for about four minutes as long as
one of the doors or the luggage lid is open.
The dipped headlights stay on for about 30 seconds to light up the
area in front of the car after all the doors and the luggage lid have
been closed.

tion, you can leave it switched on permanently. As the system is
controlled via a light sensor, it will only work in dark conditions.

photo-transistor integrated in the instrument cluster. When the
vehicle's lights are switched on, the illumination of the centre
console and instruments (needles and dials) is automatically
adjusted according to the prevailing light conditions. The driver can
also vary the brightness of the illumination manually if required:
With the ignition switched on
When the ignition is on, the basic level of brightness of the needles
in the instrument cluster can be adjusted by turning the thum-
bwheel.
