Limits of ultrasonic measurement
The parking assistant system cannot detect:
– sound-absorbing obstacles (e.g. powder
snow),
– sound-reflecting obstacles (e.g. glass surfac-
es, flat painted surfaces)
– and very thin obstacles.
– Other ultrasound sources (e.g. pneumatic
brakes of other vehicles, jackhammers) can in-
terfere 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 cov-
ered 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.
