General information: Function:

The Acoustic Parking System (APS) consists of:

Control module for parking aid -J446-
Left rear parking aid sensor -G203-
Left rear center parking aid sensor -G204-
Right rear center parking aid sensor -G205-
Right rear parking aid sensor -G206-
Warning buzzer for parking -H15-

After switching ignition on, a self-test is performed that is completed in less than a second.

The control module is now permanently in operation, however the distance recognition is only activated with shifting into reverse gear.

When the parking assistance is ready, a short signal is sounded, (delay of one second for automatic vehicles due to P-D shift).

If during a self test a malfunction was detected in the system, a continuous tone will sound for 5 seconds.

The distance warning starts while driving in reverse gear from approx. 1.5 m to the obstruction. The warning consists of sound impulses with a duration of 75 ms.

The pauses between chime impulses get shorter as the gap between vehicles gets smaller. For gaps under 25 cm, the chime becomes constant, volume and pitch (frequency) can be adapted using the VAG1551. See ADAPTATION .

Special case: Driving backward along a wall
