Indicator and warning lamps
The concept
The indicator and warning lamps can light up in
different combinations and colors.
Some lamps are tested for proper function by
briefly lighting up during starting of the engine
or when the ignition is switched on.
Explanatory text messages
Text messages at the bottom edge of the Con-
trol Display explain the meaning of the dis-
played indicator and warning lamps.
Additional information, e.g. on the cause of a
malfunction and on the corresponding need to
take action can be displayed via the Check Con-
trol, refer to page83.In urgent cases, this information will be shown
as soon as the corresponding lamp comes on.

Starting engine
Do not run the engine in closed rooms,
otherwise the inhalation of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the
engine running, as such a vehicle represents a
potential safety hazard.
Before leaving the vehicle with the engine run-
ning, select the idling position, or shift the trans-
mission into position P and firmly apply the
handbrake, otherwise the vehicle can begin to
roll.<
Avoid frequent starting in quick succes-
sion or repeated starting attempts in
which the engine does not start. Otherwise, the
fuel is not burned or inadequately burned and
there is a danger of overheating and damaging
the catalytic converter.<
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive at a moderate engine
speed.

Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp lights up, and a sig-
nal also sounds when starting off. The
handbrake is applied.
Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If exceptional circumstances should
make it necessary to apply the handbrake
while the vehicle is in motion, do not pull it too
firmly. In doing so, continuously press the but-
ton of the handbrake lever. Otherwise, too firm
an application of the handbrake can lock up the
rear wheels and cause the rear of the car to
swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is applied.<
Manual transmission
While shifting in the 5th/6th gear lane,
press the gearshift lever toward the right,
otherwise accidental shifting into the 3rd or 4th
gear could result in engine damage.<

lights up, together with the indicator
lamps for ABS, DSC and Tire Pressure
Monitor or Flat Tire Monitor. A mes-
sage appears on the Control Display.
The driving-stability control systems
have failed. Conventional braking effi-
ciency remains available without limita-
tions. While you may continue, you
should remember to proceed cau-
tiously and drive defensively while avoiding full
brake applications. The Tire Pressure Monitor
or the Flat Tire Monitor is also malfunctioning.
Have the system checked as soon as possible.

Starting assistant
The starting assistant enables you to start off
conveniently on slopes. The handbrake is not
required for this purpose.
1.Hold the vehicle with the brake.
2.Release the brake and begin to drive imme-
diately.
The starting assistant holds the vehicle
for approx. 2 seconds after the brake is
released. After releasing the brake, begin to
drive immediately; otherwise, the starting assis-
tant no longer holds the vehicle after approx.
2 seconds and your vehicle will start to roll
backward.<
Dynamic Drive*
The concept
Dynamic Drive minimizes body roll and opti-
mizes vehicle stability during cornering and
evasive maneuvers.
Dynamic Drive is based on active stabilizers on
the front and rear axles. Suspension compli-
ance adapts to suit driving conditions, varying
from performance-oriented during cornering to
smooth and comfort-oriented when the vehicle
is proceeding in a straight line. During vehicle
operation, the system continuously runs
through closed-loop control cycles lasting only
fractions of a second.
The system assumes operational status each
time you start the engine.
