vethe no tes on driving systems and your
re sponsibility; you may otherwise failto recognise
dangers (/ page 152).
If a vehicle is de tected abo vespeeds of appr ox-
imately 12 km/h and this vehicle subsequently
enters the monitoring range directly next toyour
ve hicle, thewa rning lamp in the outside mir ror
lights up red.
If a vehicle is de tected close toyour vehicle in the
lateral monitoring range and you switch on the turn
signal indicator in the cor responding direction, a
wa rning tone sounds. The redwa rning lamp in the
outside mir ror 0ashes. If the turn signal indicator
re mains switched on, all other de tected vehicles
are indicated only bythe 0ashing of there dwa rn-
