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.
To achieve this, the vehicle is equipped
with air struts at the rear axle instead of
conventional shock absorbers and steel
suspension springs. 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 compressor 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.390de136
The xenon lamps light up the side and
front areas of the vehicle with signifi-
cantly more brightness and uniformity
then the traditional halogen lamps.
In a xenon lamp, an electric arc
replaces the filament in order to gener-
ate 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, a brief period is needed for
the full beam strength to build up. Maxi-
mum brightness is attained in approx.
15 seconds.390de134
Xenon lamps provide significantly-
improved visibility, especially during
adverse 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.
