DrivingVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Start/Stop button
The concept Pressing the Start/Stop button
switches the ignition on or off and
starts the engine.
Automatic transmission: the en‐
gine starts if the brake is de‐
pressed when the Start/Stop button is pressed.
Manual transmission: the engine starts if the
clutch is depressed when the Start/Stop button
is pressed.
Ignition on
Automatic transmission: press the Start/Stop
button, and do not press on the brake pedal at
the same time.
Manual-shift transmission: press the Start/Stop
button, and do not press on the clutch pedal at
the same time.
All vehicle systems are ready for operation.
Most of the indicator and warning lamps in the
instrument cluster light up for varying lengths of
time.
To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.
The ignition switches off automatically:▷When the vehicle is locked, if the low beams
are switched on.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.▷If the engine is switched off and the ignition
is switched on, the system automatically
switches to the radio ready state when the
door is opened if the lights are switched off
or the daytime running lights are switched
on.
If the engine is switched off and the ignition
is switched on, the system automatically
switches to the radio ready state when the
door is opened if the lights are switched off.
Ignition off
Automatic transmission: press the Start/Stop
button again, and do not press on the brake
pedal at the same time.
Manual-shift transmission: press the Start/Stop
button again, and do not press on the clutch
pedal at the same time.
All indicator lamps in the instrument cluster go
out.
To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.

Driving stability control systemsVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and 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.
Brake assistant
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.
DSC Dynamic Stability
Control
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. Subjectto 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
responsibility 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.◀
Indicator/warning lamps The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is re‐
duced during acceleration and when driving in
bends.
To increase vehicle stability, activate DSC again
as soon as possible.
Deactivating DSC Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐
strument cluster and DSC OFF is displayed.
The DSC system is switched off.
Activating DSC Press the button.
DSC OFF and the DSC OFF indicator
lamp go out.Seite 104ControlsDriving stability control systems104

Drive-off assistant
This system supports driving away on gradients.
The parking brake is not required.
1.Hold the vehicle in place with the foot brake.2.Release the foot brake and drive away with‐
out delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load or when a trailer
is being used, the vehicle may roll back slightly.
Driving off without delay
After releasing the foot brake, start driving
without delay, since the drive-off assistant will
not hold the vehicle in place for more than ap‐
prox. 2 seconds and the vehicle will begin rolling
back.◀
