Acoustic warnings

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 midrange loudspeaker in the left/right-hand front doors or the mid-range 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
