failto
de tect some vehicles and is no substitute for
attentive driving. Alw ays ensure that there is suf‐
fi cient dis tance tothe side forot her road users
and obs tacles.
If a vehicle is de tected ab ove speeds of appr ox‐
imately 7.5 mp h (12 km/h) and this vehicle sub‐
sequently enters the monitoring range di rectly
next toyour vehicle, thewa rning lamp in the out‐
side mir ror lights up red.
