responsibility for parking. The system
consists of four ultrasonic parking
sensors in the rear bumper.
Note
Attached parts in the detection area
cause system malfunction.
Activation
When reverse gear is engaged, the
system is activated automatically. An
obstacle is indicated by audio signals.
The interval between the signals
becomes shorter as the vehicle gets
closer to the obstacle.
When the distance is less than
40 cm, the signal sounds continued.
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.
Deactivation
Deactivated in drive, Park or if there
is an error.
The system might not detect the
obstacle when the vehicle is driven
above a 10 km/h.
Fault
In the event of a fault in the system,
r illuminates.
Additionally if the system does not
work due to temporary conditions like
snow covered sensors, r
illuminates.
Caution
The parking assist system should
only be considered as a
supplementary function. The
driver must check the rear.
The audible warning signal can be
different depending on the objects.
The audible warning signal might
not activate in case the sensor is
frozen or stained with dirt or mud.
Do not push or scratch the surface
of the sensor. This will likely
damage the covering.
Driving and operating
There is a chance of malfunction
of the parking assist system when
driving on uneven surfaces such
as woods, gravel roads, jagged
roads or slopes.
The parking assist system might
not recognise sharp objects, thick
winter clothes or other thick and
soft materials could absorb the
frequency.
Caution
When receiving other ultrasonic
signals (metal sound or air braking
noises from heavy commercial
vehicles), the parking assist
system may not work properly.
Clean dirty sensors with a soft
sponge and clean water.
You should continue to keep
watching the mirrors or turning
your head backwards. Normal
precautions when reversing
should be maintained. Do not
press or shock the sensors by
