CONTROLS
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 when obstacles are
detected.
Lanes are faded in for better estimation of the re‐
quired space.
When the image of the rearview camera is dis‐
played, 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 equip‐
ment, it is warned in the PDC display against ve‐
hicles approaching in the front or rear from the
side.
