Display
Obstacle markings are displayed at the sides of
the vehicle to protect the vehicle's flanks.
▷
Coloured markings: warning that obstacles
have been detected.
▷
Grey markings, hatched surface: no obstacles
have been detected.
▷
No markings, black surface: the area adjacent
to the vehicle has not yet been detected.
Limits of flank protection
The system only shows stationary obstacles that
were previously detected by the sensors when
driving past.
The system does not detect whether an obstacle
subsequently moves. The markings are shown in
black after a certain time when the vehicle is sta‐
tionary. The area next to the vehicle must be de‐
tected again.
