Side View
The concept
Side View provides an early look at cross traffic
at blind driveways and intersections. Road users
concealed by obstacles to the left and right of
the vehicle can only be detected relatively late
from the driver's seat. To improve visibility, two
cameras in the front of the vehicle record the
traffic situation on each side.
Notes
The images from both cameras are shown si‐
multaneously on the Control Display.
Check the traffic situation as well
Check the traffic situation around the ve‐
hicle on blind driveways and intersections with
your own eyes. Otherwise, an accident could re‐
sult from road users or objects located outside
the picture area of the Side View cameras.◀
