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:
■ 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 94 . Press
the MENU button on the turn signal
lever to select Vehicle Information
Menu X and turn the adjuster
wheel to choose following distance
indication page.

Parking assist9 Warning
It is the driver, however, who bears
full responsibility for the parking
manoeuvre.
Check always environment when
driving backwards or forwards
while using parking assist system.
Rear parking assist
The rear parking assist makes
parking easier by measuring the
distance between the vehicle and
rear obstacles. It informs and warns
the driver by giving acoustic signals.

Driving and operating159
When driving forward with low speed
the front parking assist can also be
activated by pressing the parking
assist button r or D briefly.
Once the button is pressed within an
ignition cycle, the front parking assist
is always reactivated when the
vehicle underruns a certain value.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind and in
front of the vehicle. Depending on
which side the vehicle is closer to an
obstacle, you respectively will hear
acoustic warning signals in the
vehicle. The interval between the
sounds becomes shorter as the
vehicle gets closer to that obstacle.
When the distance is less than about 30 cm, the sound is continuous.
Additionally the distance to obstacles
is shown in the Driver Information
Centre.
The distance indication in the Driver
Information Centre can be inhibited
by vehicle messages with a higher
priority. After approving the message
by pressing the SET/CLR button on
the turn signal lever, distance
indication appears again.

162Driving and operating
A successful parking manoeuvre is
indicated by the End position symbol.
Pay attention always to the sound of
the front-rear parking assist.
Continuous sound means that the
distance to an obstacle is less than
about 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.

Notice
After production the advanced
parking assist needs a calibration.
For an optimal parking guidance a
driving distance of at least 6 miles
with many curves 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 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.
Side blind spot alert is active from
speeds of 6 mph up to 87 mph.
Driving faster than 87 mph
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.
