136Driving and operatingOn vehicles equipped with radar
sensor and front camera, the forward
collision alert operates from 5 km/h to
140 km/h when a vehicle has been
detected.
Alerting the driver
The driver is warned by following
alerts:
● Symbol , and a warning
message are displayed in the
Driver Information Center, when
the distance to the vehicle ahead
gets to small.
● Symbol , and a warning
message are displayed in the
Driver Information Center and a
warning chime sounds, when a
collision is imminent and
immediate driver's action is
required.9 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.9 Warning
The usage of a license plate
support may have an impact on
the proper operation of the radar
unit and may limit sensor
perfomance. Vehicles or
pedestrians driving or walking
ahead may not be detected by the
system.
Do not use a a license plate
support to ensure proper system
functionality.
Selecting the alert sensitivity
Three alert sensivities can be
selected in the settings of the active
emergency braking within the vehicle personalisation 3 77.
The chosen setting will be memorised
when the ignition has been switched
off. The alert timing will vary based on
selected alert setting and vehicle
speed. Consider traffic and weather conditions when selecting the alert
timing.
Deactivation
The system can only be deactivated
by deactivating the active emergency braking in the vehicle personalisation
3 77. When ignition is switched on
next time, system is activated.
System limitations Forward collision alert is designed to
warn on vehicles, but may react also
to other objects.
138Driving and operatingThe system can only be deactivated
by deactivating the active emergency braking in the vehicle personalisation

measures the distance between the
vehicle and obstacles in front and
140Driving and operatingbehind the vehicle. It informs and
warns the driver by giving acoustic
signals and display indication.
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency.
The system operates with ultrasonic
parking sensors in the rear and front
bumper.
Activation
In addition to the rear parking assist,
the front parking assist is triggered
when an obstacle is detected in front

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.
