Driving stability control systems

Antilock Brake System ABS

ABS prevents locking of the wheels during brak‐
ing.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.

Electronic brake-force

distribution

The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.

Dynamic Brake Control DBC

When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. It thus helps to achieve the shortest
possible braking distance during full braking.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.

Dynamic Stability Control

DSC

The concept

DSC prevents traction loss in the driving wheels
when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Subject
to physical limits, DSC helps to keep the vehicle
on a steady course by reducing engine speed
and by applying brakes at individual wheels.

Adjust your driving style to the situation

An appropriate driving style is always the re‐
sponsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀

Deactivating/activating the DSC OFF

program

The program can be deactivated/activated via

Dynamic Driving Control, refer to page 88

.

For better control

The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has

failed.

Dynamic Traction Control

DTC

The concept

The DTC system and the TRACTION program
are a variant of the DSC in which forward mo‐
mentum is optimized.
The system ensures maximum forward momen‐
tum on special road conditions, e.g., unplowed
snowy roads, but driving stability is limited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC un‐
der the following special circumstances:

When driving in slush or on uncleared,
snow-covered roads.

When rocking the vehicle or driving off in
deep snow or on loose surfaces.

When driving with snow chains.
