  • Depending on the equipment version: while approaching detected obstacles if the speed is slower than approx. 2.5 mph/4 km/h. The activation distance depends on the situation in question.

You may switch automatic activation when obstacles are detected on and off.

Warning

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 PDC signal tone volume can be adjusted.

Via iDrive:

1. "CAR".

2. "Settings".

3. "Driver Assistance".

4. "Parking and maneuvering".

5. "Volume PDC signal".

6. Set the desired value.

The setting is stored for the driver profile currently used.

Visual warning

Driver assistance systems

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 when obstacles are detected.

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:

1. Press the Controller to the left, if needed.

2. For instance "Park. sensors only".

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.
