Signal tones
General information
An intermittent tone indicates when the vehicle is approaching an object. For instance, 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, the shorter the intervals.
If the distance to a detected object is less than approx. 10 inches/25 cm, a continuous tone is sounded.
If there are objects in front of and behind the vehicle at the same time, with a distance smaller than approx. 10 in/25 cm, an alternating constant tone will sound.
Steptronic transmission: the intermittent tone and constant tone are switched off if the selector lever position P is engaged.
The intermittent tone is switched off after a short time when the vehicle is stationary.
Volume
The ratio of the PDC signal tone volume to the entertainment volume can be adjusted.
Via iDrive:
1. "My Vehicle".
2. "iDrive settings".
3. "Tone".
4. "Volume settings".
5. "PDC"
6. Set the desired value.
The setting is stored for the driver profile currently used.
Visual warning
The approach of the vehicle to an object is shown on the Control Display. Objects that are farther away are already displayed on the Control Display before a signal sounds.
The display appears as soon as PDC is activated.
The range of the sensors is represented in the colors green, yellow and red.
Pathway lines are faded in for better estimation of the required space.
When the image of the rearview camera is displayed, the switch can be made to PDC or to a different view with obstacle markings as needed: "Rear view camera".
Cross traffic warning: depending on the equipment, it is warned in the PDC display against vehicles approaching in the front or rear from the side.
