Restart of the engine by the
driver Depress the clutch pedal to restart the
engine.
The engine start is indicated by the
needle at the idle speed position in
the tachometer.
If the selector lever is shifted out of
neutral before depressing the clutch
first, control indicator - illuminates
or is shown as a symbol in the Driver Information Centre.
Control indicator - 3 89.
Restart of the engine by the
stop-start system The selector lever has to be in neutral
to enable an automatic restart.
If one of the following conditions
occurs during an Autostop, the
engine will be restarted automatically by the stop-start system:
■ The stop-start system is manually deactivated
■ the bonnet is opened■ the driver's seat belt is unfastened and the driver's door is opened
■ the engine temperature is too low
■ the charging level of the vehicle battery is below a defined level
■ the brake vacuum is not sufficient
■ the vehicle is driven at least at walking speed
■ the climate control system requests
an engine start
■ the air conditioning is manually switched on
If the bonnet is not fully closed, a
warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop during restart might be noticeable.
Parking ■ Do not park the vehicle on an easily
ignitable surface. The high
temperature of the exhaust system
could ignite the surface.■ Always apply parking brake. Apply manual parking brake without
pressing release button. Apply as
firmly as possible on downhill or uphill slopes. Depress the foot
brake at the same time to reduce
operating force.
Apply electric parking brake by pulling switch m for approx.
one second.
■ Switch off the engine and ignition. Turn the steering wheel until the
steering wheel lock engages.
■ If the vehicle is on a level surface or
uphill slope, engage first gear or set the selector lever to P before
switching off the ignition. On an
uphill slope, turn the front wheels
away from the kerb.
If the vehicle is on a downhill slope,
engage reverse gear or set the selector lever to P before switching
off the ignition. Turn the front
wheels towards the kerb.
■ Lock the vehicle and activate the anti-theft alarm system.
Driving and operating145
ABS starts to regulate brake pressureas soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting off the system performs
a self-test which may be audible.Control indicator u 3 90.
Adaptive brake light
During full braking, all three brake
lights flash for the duration of ABS
control.
Fault9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
Manual parking brake
Always apply parking brake firmly
without operating the release button,
and apply as firmly as possible on a
downhill or uphill slope.
To release the parking brake, pull the lever up slightly, press the release
button and fully lower the lever.
To reduce the operating forces of the
parking brake, depress the foot brake
at the same time.

TC is reactivated by pressing the b
button again.
TC is also reactivated the next time
the ignition is switched on.
Electronic Stability Control
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip. It also
prevents the drive wheels from
spinning. ESC operates in
combination with the Traction Control system (TC) 3 147.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the wheels are braked individually. This
considerably improves the driving stability of the vehicle on slippery road
surfaces.

Deactivation
For a more sporty behaviour ESC and

remains active, k illuminates
■ hold button b pressed for min.
5 seconds: TC and ESC are
deactivated, k and n illuminate.
Additionally the selected mode is
displayed as status message in the
Driver Information Centre.
If the vehicle comes into threshold
with deactivated ESP, the system will reactivate ESP for the time duration
of the threshold, when the brake pedal is depressed once.
ESC is reactivated by pressing the
b button again. If the TC system was
previously disabled, both TC and
ESC are reactivated.
ESC is also reactivated the next time
the ignition is switched on.Interactive driving system

and not to replace his attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds of approx. 30 to
200 km/h. Deviations from the stored
speeds may occur when driving uphill or downhill.
For safety reasons the cruise control cannot be activated until the foot
brake has been operated once.
Activating in first gear is not possible.
Do not use the cruise control if it is not advisable to maintain a constant
speed.
With automatic transmission, only
activate cruise control in automatic

Forward collision alert The forward collision alert can help to
avoid or reduce the harm caused by
front-end crashes. If a vehicle directly
ahead is approached too quickly, a
warning chime and alert in the Driver
Information Centre is provided.
Forward collision alert uses the front
camera system in the windscreen to
detect a vehicle directly ahead, in
your path, within a distance of approx. 60 metres.
The green illuminated vehicle ahead
symbol A appears in the
speedometer when the system has
detected a vehicle in the driving path.
Precondition is, that forward collision
alert is not deactivated by the button
V .
Activation Forward collision alert operates
automatically above 40 km/h, if it is
not deactivated by button V, see
below.

General information9Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the valid
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. He shall always be ready to take action and apply the
brakes.
System limitations
The system is designed to warn only for vehicles, but may react also on
other objects.
In the following cases, forward
collision alert may not detect a vehicle
ahead or sensor performance is
limited:
■ on winding roads,
■ when weather limits visibility, such as fog, rain, or snow,
■ when the sensor is blocked by snow, ice, slush, mud, dirt, or
windscreen damage.
Following distance
indication The following distance indication
displays the distance to a preceding
moving vehicle. The front camera in
the windscreen is used to detect the
distance of a vehicle directly ahead in
the vehicle's path. It is active at
speeds above 40 km/h.
When a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre 3 94 . Press
the MENU button on the turn signal
lever to select Vehicle InformationMenu X and turn the adjuster
wheel to choose following distance
indication page.
The minimum indicated distance is
0.5 seconds.
If there is no vehicle ahead or the vehicle ahead is out of range, two
dashes will be displayed: -.- s.
