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 covered with ice.

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.
