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 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:

Advanced parking assist9 Warning
The driver bears full responsibility
for accepting the parking slot
suggested by the system and the
parking manoeuvre.
Always check the surrounding
area in all directions when using
advanced parking assist.
The advanced parking assist system manoeuvres the driver into a parkingslot by giving instructions in the Driver Information Centre and via acoustic
signals. The driver must control
acceleration, braking, steering and
gearshifting.
The system uses the sensors of the
front-rear parking assist in
combination with two additional
sensors on both sides of the front and rear bumper.
Driving and operating167
The parking slot suggestion of the
system is accepted when the vehicle is stopped by the driver within
10 metres after the "Stop" message is given. The system calculates the
optimal route into the parking slot. Then it manoeuvres the driver into the
slot by giving detailed instructions.The instructions in the display show:
● A hint when driving faster than 30 km/h.
● The demand to stop the vehicle, when a parking slot is detected.
● The direction of driving during the
parking manoeuvre.
● The steering wheel position during parking.
● For some of the instructions a progress bar is shown.A successful parking manoeuvre is
indicated by the 'End position'
symbol.
Always pay attention to the sound of
the front-rear parking assist.
Continuous sound means that the
distance to an obstacle is less than approx. 30 cm.

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
Driving and operating169correct distance indication in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist systems do not
detect objects outside the
detection range.
Note
The parking assist system can be
activated and deactivated by
changing the settings in the
Info-Display. If a trailer coupling is

Vehicle personalisation 3 104.
Note
The parking assist system
automatically detects factory-fitted
towing equipment. It is deactivated
when the connector is plugged in.
It is possible that the sensor detects
a non-existing object (echo
disturbance) caused by external
acoustical or mechanic
disturbances.
Advanced parking assist system
may not respond to changes in the
parking space after initiating a
parallel parking manoeuvre.
Note
After use the advanced parking
assist requires a calibration. For
optimal parking guidance, a driving
distance of at least 35 km, including
a number of bends, is required.
Side blind spot alert The Side blind spot alert system
detects and reports objects on either
side of the vehicle, within a specified
"blind spot" zone. The system
displays a visual alert in each exterior
mirror, when detecting objects that
may not be visible in the interior and
exterior mirrors.
The system's sensors are located in
the bumper on the left and right side
of the vehicle.9 Warning
Side blind spot alert does not
replace driver vision.
The system does not detect:
● vehicles outside the side blind zones which may be rapidly
approaching
● pedestrians, cyclists or animals
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
When the system detects a vehicle in the side blind zone while driving
forward, either while passing a
vehicle or being passed, an amber
warning symbol B will illuminate in
the relevant exterior mirror. If the
driver then activates the turn signal,
the warning symbol B starts flashing
amber as a warning not to change
lanes.
