Vehicles with Blind Spot Assist: drivers can
also be warned of any crossing traffic when
reversing out of a parking space. If a critical sit‐
uation is detected, symbol 1 appears in the
multimedia system display. If the driver does not
respond to the warning, the vehicle's brakes can
be applied automatically. To do this, the function
uses the radar sensors in the bumper. The area
adjacent to the vehicle is continually monitored.

or other objects, detection is not possible.

ATTENTION ASSIST
Function of ATTENTION ASSIST
ATTENTION ASSIST assists you on long, monoto‐
nous journeys, e.g. on motorways and trunk
roads. If ATTENTION ASSIST detects indicators
of fatigue or increasing lapses in concentration
on the part of the driver, it suggests taking a
break.
ATTENTION ASSIST is only an aid. It cannot
always detect fatigue or lapses in concentration
in time. The system is not a substitute for a well-
