Important hints for using the
parking assist systems
9 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 has to be paid to
low obstacles which can damage
the lower part of the bumper. If
such obstacles leave the detection
area of the sensors during
approach of the vehicle,
a continuous warning tone will
sound.
Caution
Performance of the sensor can be
reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
systems can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles involved (e.g.
off-road vehicles, mini vans,
vans). Object identification in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross section, like objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist will not avoid
a collision with objects which are
out of the detection range of the
sensors.
Note
The parking assist system
automatically detects factory-fitted
towing equipment. It is deactivated
when the connector is plugged in.
The sensor may detect a non-
existing object (echo disturbance)
caused by external acoustical or
mechanic disturbances.
Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving via a front
camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
■ no operation of turn signals
■ no brake pedal operation
■ no active accelerator operation or
speeding-up
■ no active steering
If the driver is active, no warning will
be issued.
