Activating DSC

Press the button again; the indicator lamps in
the instrument cluster go out.

To control

If the indicator lamp flashes:
DSC controls the drive forces and
brake forces.
If the indicator lamps are on:
DSC is deactivated.

DTC Dynamic Traction Control

DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special 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

Activating DTC

Press the button; the indicator lamps for DTC in
the instrument cluster come on.

To control

If the indicator lamp flashes:
DTC controls the drive forces and
brake forces.

If the indicator lamps are on:
DTC has been activated.

Deactivating DTC

Press the button again; the DTC indicator
lamps in the instrument cluster go out.

Drive-off assistant

The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the handbrake for this.

Hold the car in place by depressing the
brake.

Release the brake and drive off without
delay.

The drive-off assistant holds the car in
place for approx. 2 seconds after the

brake is released. Depending on vehicle load,
the car may roll backwards a little during this
time span. Drive off without delay after releas-
ing the brake. Otherwise, the drive-off assistant
will no longer hold the car in place after approx.
2 seconds and the car will start to roll back-
wards.

Flat Tire Monitor FTM*

The concept

The Flat Tire Monitor monitors tire pressures
while the car is being driven. The system
reports any significant loss of pressure in one
tire in relation to another.
If a tire loses pressure, its rolling radius
changes, and this in turn alters the speed of
rotation. This change is detected and is
reported as a flat tire.

Functional requirement

In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
