The system issues a two-phase warning of a danger of collision at speeds above approx. 10 mph/15 km/h. The time of these warnings may vary depending on the current driving situation.
In the process, vehicles in a similar direction of movement are observed if they are located within the detection range of the system.
When the vehicle is intentionally brought into contact with a vehicle, the collision warning is delayed to avoid misleading warnings.
This warning is issued, for example, when there is the impending danger of a collision or the distance to the vehicle ahead is too small.
Warning of the imminent danger of a collision when the vehicle approaches another vehicle at a relatively high differential speed.

The selected channel is stored for the remote control currently in use.
Display in the instrument cluster
The collision warning can be issued in the instrument cluster, in the Head-up Display, and acoustically.
Adapting your speed and driving style
The display does not relieve the driver of the responsibility to adapt his or her driving speed and style to the traffic conditions.◄
Due to system limitations, warnings may be not be issued at all, or may be issued late or improperly. Therefore, always be alert and ready to intervene; otherwise, there is the danger of an accident occurring.◄
The detection capacity of the camera and the collision warning has limitations.
This may result in the warning not being issued or being issued late.
For example, the following situations may not be detected:
► Slow moving vehicles when you approach
them at high speed.
► Vehicles that suddenly swerve in front of you or sharply decelerating vehicles.
► Vehicles with an unusual rear appearance.
► Two-wheeled vehicles ahead of you.
The system may not be fully functional in the following situations:
► In heavy fog, rain, sprayed water or snowfall.
► In tight curves.
► If the camera view field or the front windshield are dirty or covered.
► When driving toward bright lights.
► In the case of vehicles with insufficiently visible tail lamps.
► In the case of partially covered vehicles.
► Up to 10 seconds after the start of the engine, via the Start/Stop knob.
► During the calibration process of the camera immediately after vehicle shipment.
Depending on the set prewarning time, this may result in increased false warnings.
The camera is located near the base of the mirror.
Keep windshield clean and clear in the area in front of the interior rear view mirror.
