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 radar sensor 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.
▷ Pedestrians.
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 radar sensor is dirty or covered.
Prewarning sensitivity
Depending on the set prewarning time, this may result in increased false warnings.
