CONTROLS
The recording range of the sensors is shown in
green, yellow and red if obstacles are detected
within the range.
Driving path lines are displayed for better estima‐
tion of the space required.
If the rear-view camera image is shown, it is pos‐
sible to change over to PDC or, if required, to an‐
other view with obstacle markings:
1. If necessary, push the Controller to the left.
2. For example "Parking sensors"
Crossing traffic warning, see page 217: depend‐
ing on the equipment, the PDC display also
warns about vehicles approaching from the sides
at the front and rear.
Depending on the equipment
version: emergency braking
function, Active PDC
Principle
The emergency brake function of PDC initiates
emergency braking in the event of imminent col‐
lision danger.
General
Due to the system limits, a collision cannot be
prevented under all circumstances.
The function is available at speeds below walking
speed when driving or rolling in reverse.
Pressing the accelerator pedal interrupts the
braking intervention.
After emergency braking to a stop, it is possible
to continue a slow approach to the obstacle. To
approach, lightly depress the accelerator.
If the accelerator is depressed more firmly, the
vehicle pulls away as normal. Manual braking is
possible at any time.
The system uses the ultrasonic sensors of PDC
and Park Assistant.
