Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired if:
Rdirt on the sensors or anything else
covering the sensors
Rpoor visibility, e.g. due to fog, heavy rain,
snow or spray
Rnarrow vehicles, e.g. motorcycles or
bicycles
Rthe road has very wide lanes
Rthe road has narrow lanes

lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may
be the case if there are vehicles driving at the
inner edge of their lanes.
Due to the nature of the system:
Rwarnings may be issued in error when
driving close to crash barriers or similar
solid lane borders.
