Limitations for radar
device
The radar unit has certain limitations - which in
turn also limits those functions that use the unit.
A driver should be aware about the following
examples of limitations.
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 func-
tions being reduced, being switched off com-
pletely 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 func-
tion responses. The driver is always responsible
for intervening in such a situation and maintain-
ing 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.
