General notes
ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h range. If ATTENTION ASSIST detects
typical indicators of fatigue or increasing lapses
in concentration on the part of the driver, it sug-
gests taking a break.
