Blind Spot Assist
Introduction
Blind Spot Assist assists the driver in
rec
ognising the trac situation behind
the vehicle.
Radar sensors behind the rear bumper cov-
er monitor the area behind the vehicle. The
system measures the distance and speed
dierence in relation to other vehicles and
informs the driver by means of visual sig-
nals in the housings of the exterior mirrors.
Use Blind Spot Assist only on paved roads.
