Highly sensitive sensors monitor the
number of revolutions of the wheels,
steering angle, lateral acceleration,
brake pressure and the movement
of the vehicle around its vertical axis.
If differences in wheel speed should
occur, the system will recognize the
danger this loss of traction causes and
reduce the drive torque going to the
wheels. The system will also apply the
brakes specifically to the rear wheels,
if necessary.
In addition, DSC permanently monitors
the vehicle's current operating condi-
tion and compares it with an ideal con-
dition that is calculated from the sen-
sor's signals. If differences such as
under- or oversteering should occur,
DSC will stabilize the vehicle in frac-
tions of a second by reducing engine
power output, applying the brakes to
individual rear wheels Ð and to specific
front wheels, too, if necessary. As a
result, dangerous skids can be pre-
vented even as they are beginning.You may need some time to become
accustomed to this system's interven-
tion. However, it provides optimum
drive force and vehicle stability.
The braking intervention may be
accompanied by sounds specific to
the system.
The safety belt tensioner responds to
severe frontal collisions by tightening
the belt to ensure that occupants
remain firmly positioned in their seats.
A gas-pressure system retracts the
buckle assembly to tension the shoul-
der and lap belts within fractions of a
second. This reduces the tendency to
slide under the lap belt.

Xenon lamps
*
Xenon lamps illuminate the side and
front areas of the vehicle much more
brightly and with greater uniformity than
traditional halogen lamps.
In a xenon lamp, an electric arc re-
places the filament 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 im-
proved visibility, especially during ad-
verse weather and poor driving condi-
tions, 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.
Thus the highway is always optimally
lighted and drivers in oncoming traffic
are not blinded.
Xenon lamps make a significant contri-
bution to highway safety since other
highway users, bicyclists and motorcy-
clists in the right lane, and pedestrians
are more easily detected.
So that you will have important
specifications available when you
stop to refuel, we recommend
that you supplement this table
with data which apply to your
vehicle.
