System limits
Be alert
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.
Detection range
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.
Functional limitations
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.
Prewarning sensitivity
Depending on the set prewarning time, this may result in increased false warnings.
