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.
Caution
Sensitivity of the sensor could be
reduced caused by external
influences e.g. layers on the
sensor surface (ice, snow, mud,
soiling, multiple varnishing/
painting, etc.).
Sensor could detect a non-existing
object ("echodisturbance") caused
by external acoustical
disturbances e.g.another park
pilot system.
Sensor could detect a non-existing
object ("echodisturbance") caused
by external mechanic
disturbances e.g. carwash, rain,
extreme wind conditions, hail etc.
Performance of the park
assistance systems could be
reduced caused by changing of
sensor position by external
changes to the vehicle,
e.g.lowering of the shock absorber
over lifetime due to: temperature
changes, changing of
tyres,loading of the vehicle,
lowering/tuning of the vehicle etc.
Particular conditions apply for high
vehicles (e.g. off-road vehicles,
mini vans, transporters). Object
identification in the upper part of
the vehicle can not be guaranteed.
Performance of the park
assistance systems could be
reduced by acoustic coupling to
the vehicle caused by icing over.
Objects with a very small reflection
cross section may not be
detected.
Note
Sensor could detect a nonexisting
object (echo disturbance) caused by
external acoustical or mechanic
disturbances.
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 side rear view mirror,
when detecting objects that may not
be visible in the inside and outside
rear view mirrors.
The system's sensors are located in
the bumper on the left and right side
of the vehicle.
