Rain sensor
*
Depending on the degree of wetness
on the windshield, the rain sensor
controls the operation of the windshield
wipers.
Infrared light is carried along the
surface of the windshield in an optical
conductor in such a manner that it is
reflected completely when the wind-
shield is dry. The quantity of reflected
light is measured.
If there is moisture on the glass, the
amount of light reflected is reduced
since the infrared light at the surface of
the windshield can escape. The quan-
tity of reflected light is thus a means of
gauging the degree of wetness on the
windshield.390de133
When the system is set to the "Inter-
mittent" wiper speed, the wipers react
immediately Ð if water is splashed onto
the windshield by vehicles traveling
ahead of you, for example. As a result,
the rain sensor provides a contribution
to driving safety and comfort.

Xenon lamps
*
The xenon lamp provides forward illu-
mination with significantly more bright-
ness and uniformity than the traditional
halogen lamp.
In a xenon lamp, an electric arc replaces
the filament in order to generate intense
illumination. A gas mixture in a quartz
glass tube with metal vapor is ignited by
a high electric voltage. The arc that is
generated is then sustained by a lower
voltage. When the lamp is turned on,
there is a brief warm-up period.
Maximum brightness is attained in
approx. 15 seconds.390de134
Xenon lamps provide significantly
improved visibility, especially during
adverse weather conditions and difficult
driving situations (e. g. driving at night in
heavy rain or through road repair areas
where there are no lane markers).
Vehicles with xenon lamps are equipped
with automatic headlamp range control.
As a result, the lane ahead of you is
always optimally lighted, even under
varying load conditions, and drivers in
oncoming traffic are not blinded.
Xenon lamps make a significant contri-
bution to highway safety since other
highway users, bicyclists and motor-
cyclists in the right lane, and pedes-
trians are more easily detected.
