Level control system
Xenon lamps
*
The level control system for the rear
axle maintains constant ground clear-
ance of your vehicle, even when carry-
ing a load.
axle maintains constant ground clear-
ance of your vehicle, even when carry-
ing a load.
For this purpose, the vehicle is
equipped with air springs instead of
steel springs at the rear axle. With the
help of two sensors, an electronic
control unit calculates the height of the
body at all times and, if it is required, it
allows air which is generated in a com-
pressor to flow into the air springs.

As a result of the pressure increase in
the air springs, the level control system
ensures not only constant ride height,
but also ride comfort which is indepen-
dent of the load the vehicle is carrying.

Xenon lamps illuminate the side and
front areas of the vehicle with signifi-
cantly more brightness and uniformity
than traditional halogen lamps.

In a xenon lamp, an electric arc re-
places 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 period of high
intensity. Maximum brightness is
attained in approx.15 seconds.

Xenon lamps provide significantly-im-
proved visibility, especially during ad-
verse weather conditions and driving
situations (driving at night in heavy rain
or through road repair areas where
there are no lane markers, for instance).

Vehicles with xenon lamps
are
equipped with automatic headlamp
range control. As a result, the highway
is always optimally lighted, regardless
of load conditions, and drivers in on-
coming traffic are not blinded.

Xenon lamps make a significant contri-
bution to highway safety since other
highway users, or bicyclists and motor-
cyclists in the right lane, and pedestri-
ans are more easily detected.
