Antilock Brake System ABS
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page
99
.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake assist
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC optimizes driving stability and traction. In
addition, the system recognizes unstable driv-
ing situations such as understeering and over-
steering, and helps keep the vehicle on a safe
course within physical limits by reducing engine
power and applying the brakes on individual
wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taking risks, as this could
result in an accident.

Deactivating DSC
Press the DSC OFF button for longer than
approx. 1 second; the indicator lamps for DSC
in the instrument cluster light up. Stabilizing
and drive-output promoting actions are no
longer executed.
You may find it useful to briefly deactivate DSC
under the following exceptional circumstances:
>
When driving uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads
>
When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>
When driving with snow chains
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the DSC OFF button again; the indicator
lamps in the instrument cluster go out.
For better control
If the indicator lamp flashes:
DSC is regulating the drive and brak-
ing forces.
If the indicator lamps are on:
DSC is deactivated.
