ATTENTION ASSIST
Function of ATTENTION ASSIST
ATTENTION ASSIST can assist you on long,
monotonous journeys, e.g. on motorways and
trunk roads. If ATTENTION ASSIST detects indica‐
tors of fatigue or increased lapses in concentra‐
tion on the part of the driver, it suggests taking a
break.
ATTENTION ASSIST is only an aid. It cannot
always detect drowsiness or increased lapses in
concentration in good time. The system is not a
substitute for a well-rested and attentive driver.
On long journeys, take regular and timely breaks
that allow you to rest properly.
If fatigue or increased lapses in concentration are
detected, the ATTENTION ASSIST: Take a break!
warning appears in the instrument cluster.
You can acknowledge the message and take a
break if necessary. If you do not take a break and
ATTENTION ASSIST continues to detect increased
lapses in concentration, you will be warned again
after a minimum of 15 minutes.
If a warning is displayed in the instrument cluster,
the multimedia system offers to search for a rest
area. You can select a rest area and start naviga‐
tion to this rest area. This function can be activa‐
ted and deactivated in the multimedia system.
You can have the current ATTENTION ASSIST
assessment displayed using the
graphic menu in the on-board computer
( page 189).
