WARNING
Blind Spot Assist does not react to:
vehicles overtaken too closely on the side,
R
placing them in the blind spot area
if you overtake these with a difference in
R
speed in excess of 12 km/h
or if they approach with a great relative
R
speed and overtake you
As a result, Blind Spot Assist cannot warn
drivers in these situations. There is a risk of
an accident.
Always pay careful attention to the traffic sit-
uation and maintain a safe distance at the side
of the vehicle.
