Ultrasonic parking assist 3 197.
198Driving and operatingFront-rear parking assist
The front-rear parking assist
measures the distance between the vehicle and obstacles in front and
behind the vehicle. The system gives acoustic signals and display
messages.
The system has four ultrasonic
parking sensors each in the rear and front bumper.
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency. The signal
for front obstacles sounds via the
front speakers, for rear obstacles it
sounds from the rear of the vehicle.
Activation
When reverse gear is engaged, the
front and rear parking assist is ready
to operate.
The front parking assist is also
activated automatically at a speed up
to 11 km/h.
An illuminated LED in the parking
assist button r indicates that the
system is ready to operate.
If the vehicle exceeds a speed of
11 km/h, the front parking assist is
deactivated. The front parking assist
is always reactivated when vehicle
speed drops below 11 km/h.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind and in
front of the vehicle. Depending on
which side of the vehicle is closer to
an obstacle, you will hear acoustic warning signals on the respective
side of the vehicle. The interval
between the sounds becomes shorter as the vehicle gets closer to that
obstacle. When the distance is less
than approx. 30 cm, the sound is
continuous.
Additionally, the distance to obstacles is shown in the Driver Information
Centre 3 111.
Driving and operating199
The distance to a front and rear
obstacle is indicated by changing
distance lines around the vehicle.
Rear obstacles are indicated
acoustically and visually at the same
time.
Front obstacles are indicated visually
first. At distances less than 80 cm an
acoustic signal also sounds.
The distance indication in the Driver
Information Centre can be inhibited
by vehicle messages with a higher
priority. After approving the message
by pressing SET/CLR on the turn
signal lever or 9 on right steering
wheel control, distance indication
appears again.
Deactivation
The rear parking assist automatically
switches off when reverse gear is
disengaged.
The front parking assist is deactivated
automatically at a speed above
11 km/h.
Manual deactivation is possible by
pressing the parking assist button
r briefly.
When the system is deactivated, the
LED in the button extinguishes.
Additionally, Park Assist Off pops-up
in the Driver Information Centre when the system is deactivated manually.
After a manual deactivation, the front
parking assist is activated again if the
parking assist button r is pressed
or if reverse gear is engaged.
Fault
In the event of a fault in the system or if the system does not work due to
temporary conditions, e.g. ice
covered sensors, a message is
displayed in the Driver Information
Centre.

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.
200Driving and operating
The advanced parking assist system
manoeuvres the driver into a parking slot by giving instructions on the
Driver Information Centre and
acoustic signals. The driver must
control acceleration, braking, steering
and gear shifting.
The system uses the sensors of the
parking assist system in combination
with two additional sensors on both
sides of the front and rear bumper.
Activation
When searching for a parking slot, the
system is ready to operate by
pressing button (.
The system can only be activated at
a speed up to 30 km/h and the system searches for a parking slot at a speed
up to 30 km/h.
The maximum allowed parallel
distance between the vehicle and a
row of parked cars is 1.8 metres.
Functionality
When the vehicle passes a row of
cars and the system is activated, the
advanced parking assist system
begins looking for a suitable parking
slot. When a suitable slot is detected, a visual feedback and acoustic
signals are given in the Driver
Information Centre.
If the driver does not stop the vehicle
within 10 metres after a parking slot is
proposed, the system starts to search
for another suitable parking slot.
Driving and operating203Basic notes on using 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
correct 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.
Vehicle personalisation 3 121.
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 production, the system
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.
Driving and operating2079Warning
