Limitations for radar device
Blocked unit
The area in front of the radar unit must be cleaned on a regular basis and kept free from decals, objects, dirt, etc. – these could disrupt the radar-based functions. This may result functions being reduced, being switched off completely or giving incorrect function responses.
Wet snow or ice on the grille in front of the radar unit may disrupt radar-based functions. This may result functions being reduced, being switched off completely or giving incorrect function responses. The driver is always responsible for intervening in such a situation and maintaining a safe distance and speed.
Vehicle speed
The radar unit's ability to detect a vehicle ahead is greatly reduced if the speed of the vehicle ahead is very different to the speed of your own car.
Limited field of vision
The radar unit has a limited field of vision. In some situations another vehicle is not detected, or the detection is made later than expected.
Sometimes the radar unit is late at detecting vehicles at close distances - e.g. a vehicle that drives in between your car and the vehicle ahead.
Small vehicles, such as motorcycles, or vehicles not driving in the centre of the lane can remain undetected.
In bends, the radar unit may detect a different vehicle than intended or lose a detected vehicle from view.
Do not fit anything in front of the radar unit such as auxiliary lamps, decals, etc., since these may disrupt radar-based functions. This may result functions being reduced, being switched off completely or giving incorrect function responses.
