General information for both
variants of forward collision alert9 Warning
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 to
other metallic objects.
In the following cases, forward
collision alert may not detect a vehicle ahead or sensor performance may be limited:
■ on winding roads
■ when weather limits visibility, e.g. 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 system uses,
depending on the vehicle equipment,
either the radar behind the radiator
grille or the front camera in the
windscreen to detect the distance of
a vehicle directly ahead in your lane.
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 3 111.

event, No Traffic Sign Detection
due to Weather is indicated on the
display.
■ Traffic signs are incorrectly mounted or damaged.
■ Traffic signs do not comply with the
Vienna Convention on traffic signs
(Wiener Übereinkommen über
Straßenverkehrszeichen).Caution
The system is intended to help the driver within a defined speed
range to recognise certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not recognise
any other than the conventional
traffic signs that might give or end
a speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.
Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving, via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
by visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
■ No operation of turn signals.
■ No brake pedal operation.
■ No active accelerator operation or speeding-up.
■ No active steering.
If the driver is active, no warning will
be issued.
Activation
The lane departure warning system is activated by pressing ). The
illuminated LED in the button
indicates that the system is switched
on. When the control indicator ) in
the instrument cluster illuminates
