Driving situations
In the following situations, an indication will
be displayed in the external mirror
›››
B (arrow) or Fig. 223 B (arrow):
● When being passed by another vehicle
›››
Fig. 222 A.
● When passing another vehicle
with a speed differential of approx. 10 km/h
(6 mph). If the vehicle is passing at a consid-
226
erably higher speed, no indication will be
›››
Fig. 222 displayed.
The faster the vehicle approaches, the sooner
an indication will be displayed in the external
mirror, because the blind spot detector takes
into account the speed differential with other

vehicles. Thus even though the distance from
the other vehicle is identical, the indication
will appear sooner in some cases and later in
others.

Physical limitations inherent to the system
In some situations the blind spot detector
may not interpret the traffic situation correct-
ly. E.g. in the following situations:
● on tight bends
● in the case of lanes with different widths
● at the top of slopes
● in adverse weather conditions
