Acoustic warnings

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.

The acoustic warnings are emitted by the M-ASK via the mid-range loudspeaker.

If an object is detected by 2 ultrasonic sensors, the loudspeaker closest to the object is actuated. The mid-range loudspeaker in the left/right-hand front doors or the midrange loudspeaker on the left/right-hand sides of the rear shelf can be actuated.

If an object is detected by 3 ultrasonic sensors, the mid-range loudspeakers on the left and right-hand sides are actuated together.

The smaller the distance to the object, the faster the sequence of acoustic warning tones.

A distance of less than approx. 25 centimeters is indicated by a continuous tone.

The warning tone switches off as soon as the vehicle moves away from the object.

If the vehicle is moving directly towards a wall, the acoustic warning tone will be switched off after approx. 3 seconds so that it does not distract the driver. If the vehicle continues to approach the wall, the warning will be reactivated.

Effective range for acoustic warnings:

approx. 60 centimeters for the ultrasonic sensors at the two corners of the front bumper
approx. 70 centimeters for the two middle ultrasonic sensors in the front bumper
approx. 60 centimeters for the ultrasonic sensors at the two corners of the rear bumper
approx. 150 centimeters for the two middle ultrasonic sensors in the rear bumper
