WARNING: This page does not describe the selected car, but rather 21 other vehicles, including the 2006 BMW Z4, 2006 BMW M3, 2006 BMW M Roadster, 2006 BMW M Coupe, and 2006 BMW 550i. However, it is still accessible from the selected car via links, so may be relevant.
So long as reverse gear is engaged, an acoustic signal (reversing gong) is given via the multi-audio system controller (M-ASK) and the mid-range loudspeaker.
The reversing gong is deactivated immediately if the PDC detects an object in the effective range and emits its own acoustic warning.
Subject to change.
