warning code appears in the Driver
Information Centre. The system is not
operational.
Have the cause of the fault remedied
by a workshop.
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).
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.
ESC is operational after each engine
start as soon as the control indicator
b extinguishes.
When ESC operates b flashes.

system is necessary. This can occur
e.g. when turning the steering wheel
for one rotation with ignition switched
off. In this case, switch on ignition and turn steering wheel once from lock to
lock.
If control indicators c and b do not
extinguish after calibration, seek the
assistance of a workshop.Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance

Forward collision alert The forward collision alert can help to
avoid or reduce the harm caused by
front-end crashes.
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.
A vehicle ahead is indicated by
control indicator A.
If a vehicle directly ahead is
approached too quickly, a warning
chime and an optical alert in the
windscreen is provided.
Driving and operating155
General information
9Warning
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 appropriate
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. The driver must 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 onother 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 25 mph.
When a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre 3 95 . Press
MENU on the turn signal lever to
select Vehicle Information
Menu ? and turn the adjuster
wheel to choose following distance
indication page.
The minimum indicated distance is
0.5 seconds.
162Driving and operating
When a slot is detected, a visual
feedback on the Colour-Info-Display
and an acoustic signal is given.
If the driver does not stop the vehicle within 10 metres for parallel parking
slots or six metres for perpendicular
parking slots after a parking slot is
proposed, the system starts to search
for another suitable parking slot.
Park guiding mode
The parking slot suggestion of the
system is accepted when the vehicle
is stopped by the driver within
10 metres for parallel parking slots or
six metres for perpendicular parkingslots after the Stop message is given.
The system calculates the optimal
path into the parking slot.
A brief vibration in the steering wheel
after engaging reverse gear indicates
that the steering is controlled by the
system. Then the vehicle is steered
into the slot automatically by giving
the driver detailed instructions for
braking, accelerating and gear
shifting. The driver must keep hands
away from the steering wheel.
Always pay attention to the sound of
the front-rear parking assist.
Continuous sound indicates that the
distance to an obstacle is less than
approx. 30 cm.
If, for any reason, the driver must take over control of the steering, hold the
steering wheel only at the outer edge. Automatic steering is cancelled in thisevent.Changing the parking side
The system is configured to detect
parking slots by default on the
passenger side. To detect parkingslots on the driver side, switch on turn
signal indicator on the driver side for
the duration of the search.
As soon as the turn signal indicator is switched off, the system searches for
parking slots on the passenger side again.Display indication
The instructions on the display show:
■ General hints and warning messages.
■ A hint when driving faster than 18 mph during parking slot
searching mode, or 5 mph in
guiding mode.
■ The demand to stop the vehicle, when a parking slot is detected.
■ The direction of driving during the parking manoeuvre.
■ The demand to shift into reverse or
first gear.
■ The demand to accelerate or brake.
■ For some of the instructions a progress bar is shown in the DriverInformation Centre (DIC).
Driving and operating163
■ The successful completion of theparking manoeuvre indicated by a
pop-up symbol and a chime.
■ The cancelling of a parking manoeuvre.
Display priorities
Advanced parking assist indication in the DIC can be inhibited by vehicle
messages with a higher priority. After
approving the message by pressing
SET/CLR on the turn signal lever,
advanced parking assist instructions
appear again and the parking
manoeuvre can be continued.
Deactivation
The system is deactivated by:
■ a long press of D
■ parking manoeuvre successfully ended
■ driving faster than 18 mph during parking slot search
■ driving faster than 5 mph during parking guidance
■ driver interference on steering wheel detected■ exceeding number of maximumgear changes: eight cycles when
parallel parking or five cycles when
perpendicular parking
■ switching off the ignition
Deactivation by the driver or by the system during manoeuvring will beindicated by Parking Deactivated on
the display. Additionally, an acoustic
signal sounds.
Fault
A message appears when:
■ There is a fault in the system.
■ The driver did not successfully complete the parking manoeuvre.
■ The system is not operational.
■ Any of the deactivation reasons described above apply.
If an object is detected during parking
instructions, Stop is indicated on the
display. Removing the object will
resume the parking manoeuvre. If the
object is not removed, the system will
be deactivated. A long press of D
will activate the system and search for a new parking slot.Basic notes on parking assist
systems9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the system can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and
