Signal tones

When approaching an object, an intermittent tone is sounded that indicates the position of the object. For example, if an object is detected to the left rear of the vehicle, a signal tone sounds from the left rear speaker.

The shorter the distance to the object becomes, the shorter the intervals.

If the distance to a detected object is less than approx. 12 in/30 cm, a continuous tone is sounded.

If objects are located both in front of and behind the vehicle, an alternating continuous signal is sounded.

The intermittent tone is interrupted after approx. 3 seconds:

  • If the vehicle stops in front of an object that is detected by only one of the corner sensors.
  • If moving parallel to a wall.

The signal tone is switched off:

  • When the vehicle moves away from an object by more than approx. 4 in/10 cm.
  • When transmission position P is engaged.

Volume

You can set the volume of the PDC signal tone.

The setting is stored for the remote control currently in use.
