situation and maintain a safe distance at
the side of the vehicle.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognize
dangers (
If a vehicle is detected above speeds of approx-
imately 7.5 mph (12 km/h) and this vehicle subse-
quently enters the monitoring range directly next
ons)
to your vehicle, the warning lamp in the outside
mirror lights up red.
If a vehicle is detected close to your vehicle in the
lateral monitoring range and you switch on the turn
signal indicator in the corresponding direction, a
warning tone sounds. The red warning lamp in the
outside mirror ashes. If the turn signal indicator
remains switched on, all other detected vehicles
are indicated only by the ashing of the red warn-
ing lamp.
When you overtake a vehicle, the warning only
occurs if the di erence in speed is less than
approximately 12 mph (20 km/h).
