Signal tones
General information
An intermittent tone indicates when the vehicle is approaching an object. E.g., when 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.
When the distance to a detected object is less than approx. 8 in/20 cm, a continuous tone is sounded.
When there are objects in front of and behind the vehicle at the same time, with a distance smaller than approx. 8 in/20 cm, an alternating constant tone will sound.
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:
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 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:
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.
Additional information: Cross traffic warning
Depending on the equipment version: emergency brake function, Active PDC
Concept
The emergency braking function of PDC initiates an emergency braking in case of acute risk of collision.
General information
This function may not be available. Contact your authorized dealer's service center or another qualified service center as to whether this additional function is currently in your vehicle or when it can be installed in your vehicle in the future.
Due to system limits, a collision cannot be prevented under all circumstances.
The function is available below walking speed when driving in reverse or rolling backward.
A press of the accelerator pedal interrupts the braking intervention.
After emergency braking to a stop, further creeping toward an obstacle is possible. Proceed with caution. To move forward, lightly press the accelerator pedal and release as needed.
If the accelerator pedal is depressed longer, the vehicle drives off. Manual braking is possible at any time.
The system uses the ultrasound sensors of PDC and parking assistant.
Safety information
Warning
The system cannot serve as a substitute for the driver's personal judgment in assessing the traffic conditions. There is a risk of accident.
Adjust driving style to traffic conditions. Watch traffic and vehicle surroundings closely and actively intervene where appropriate.
Temporary switching off
The emergency brake function can be switched off temporarily: Confirm the message on the Control Display.
During continued driving in this surrounding situation, no further emergency braking will occur.
Adjusting
The system can be activated or deactivated. It is possible to set which areas on the vehicle will be protected by the system.
Via iDrive:
The setting is stored for the driver profile currently used.
With Parking Assistant: side parking aid
Concept
The system warns of obstacles on the side of the vehicle.
General information
In addition to the front and rear ultrasonic sensors, the system uses the side ultrasonic sensors.
Display
To protect the sides of the vehicle, obstacle markings are displayed on the sides of the vehicle.
Limits of the side parking aid
The system only displays stationary obstacles that were previously detected by sensors while passing them.
The system does not detect whether an obstacle moves later on. If the vehicle is stationary, the markings are shown in black after a certain time.
The area next to the vehicle must be newly captured.
