Parking Aids
Parking assistant
Function of the parking assistant
When the driver backs up, the parking assistant
system indicates the distance between the car
and a large obstacle behind it, by means of signal
tones.
Warning!
Risk of serious personal injury or death.
Parking assistant cannot detect small objects
such as children and pets. Despite use of the
parking assistant system, the driver is still
responsible for taking due care and assessing
obstacles when backing up.
Make sure that no persons, especially small
children, animals or obstacles are within the
maneuvring area.
The parking assistant system is activated automati-
cally when reverse gear is selected and the ignition
is on.
Note
Be aware that the parking assistant system is
not switched on if the car rolls backward without
reverse gear being engaged.
Ultrasound sensors
Sensors
Four ultrasound sensors in the rear bumper
measure the distance to the closest obstacle.
–
Range middle sensors around 60 in./150 cm
– Range outer sensors around 24 in./60 cm
Obstacles cannot be detected in the “blind” sensor
area (e.g. near the ground).
Note
The sensors must always be kept free of dust,
ice and snow in order to ensure that they are fully
functional.
Caution!
To avoid damaging the sensors:
Maintain sufficient distance when cleaning with
steam-jet units.
Signal tones/function
When reverse gear is selected, the parking
assistant confirms that it is switched on by issuing
a short signal tone.
A detected obstacle is signalled by an intermit-
tent tone. The intervals decrease as the obstacle
is approached.
A continuous tone sounds when the distance
becomes less than one foot. This continuous tone
can stop if the obstacle is approached closer than
one foot.
The radio volume should not be so loud as to
drown out the signal tones.
Limits of ultrasonic measurement
The parking assistant system cannot detect:
–
sound-absorbing obstacles (e.g. winter
operation, powder snow),
– sound-reflecting obstacles (e.g. glass
surfaces, flat painted surfaces)
– and very thin obstacles.
