Functionality
When the vehicle passes a row of
cars and the system is activated, the
advanced parking assist system
begins searching for a suitable
parking slot. When a suitable slot is
detected, a visual feedback on the
Driver Information Centre and an
acoustic signal are given.
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.
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.

Driving and operating201
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.
Changing the parking side
The system is configured to detect
parking slots by default on the
passenger side. To detect parking
slots on the driver side, switch on turn
indicator to the driver side for the
duration of searching.
As soon as turn indicator is switched
off, the system searches for parking
slots on the passenger side again.

Basic notes on parking assistsystems9 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. If a trailer coupling is
attached, it must be selected in the
menu.
Vehicle personalisation 3 132.
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
If engaging a forward gear and
exceeding a certain speed, the rear
parking assist will be deactivated
when the rear carrier system is
extended.
If engaging reverse at first, the
parking assist will detect the rear
carrier system and provide a buzzing
sound. Press r or D button
briefly to deactivate the parking assist.
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.

Driving and operating203Side blind spot alertThe Side blind spot alert system
detects and reports objects on either
side of the vehicle, within a specified
"blind spot" zone. The system alerts
visually 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.
Note
If the passing vehicle is at least 10
km/h faster than the passed vehicle, the warning symbol B in the relevant
exterior mirror will not illuminate.Side blind spot alert is active from
speeds of 10 km/h up to 140 km/h.
Driving faster than 140 km/h
deactivates the system, indicated by
low lighting warning symbols B in
both exterior mirrors. Reducing the speed again will extinguish the
warning symbols. If a vehicle is then
detected in the blind zone, the
warning symbols B will illuminate as
normal on the relevant side.
When the vehicle is started, both exterior mirror displays will briefly
come on to indicate that the system is operating.
