Rollover protection system
Xenon lamps
*
The rollover protection system offers
additional protection to the airbags and
the safety belts. It uses highly sensitive
sensors that respond immediately to
any unstable vehicle condition encoun-
tered while driving, e. g. a steep angle
or loss of wheel contact with the
ground. The protective bar in the rear
headrests would be triggered in this
type of situation.
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.

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 an 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.
