ATTENTION ASSIST

General notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the 37 mph (60 km/h) to
125 mph (200 km/h) range. If
ATTENTION ASSIST detects typical indicators
of fatigue or increasing lapses in
concentration on the part of the driver, it
suggests taking a break.
Important safety notes
ATTENTION ASSIST is only an aid to the
driver. It might not always recognize fatigue
or increasing inattentiveness in time or fail to
recognize them at all. The system is not a
substitute for a well-rested and attentive
driver.
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
if the length of the journey is less than
R
approximately 30 minutes
if the road condition is poor, e.g. if the
R
surface is uneven or if there are potholes
if there is a strong side wind
R
if you have adopted a sporty driving style
R
with high cornering speeds or high rates of
acceleration
