Limits of ultrasonic measurement
The parking assistant system cannot detect:
– sound-absorbing obstacles (e.g. winter opera-
tion, powder snow),
– sound-reflecting obstacles (e.g. glass sur-
faces, flat painted surfaces)
– and very thin obstacles.
Other ultrasound sources (e.g. pneumatic brakes
of other vehicles, jackhammers) can interfere with
detection of obstacles.
Fault indication
The parking assistant system indicates a fault in
two ways:
– After reverse gear has been selected, the
short signal tone is followed by a continuous
tone of the same pitch:
This indicates that sensors are soiled or cove-
red with ice.
– After reverse gear has been selected, the
short signal tone is followed by a continuous
tone with a much lower pitch:
This indicates a general system fault. Please
have the fault remedied at an authorized
Porsche dealer.
