ATTENTION ASSIST
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 speed 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. It may not
always detect fatigue or lapses in concentra-
tion until too late, or may not detect 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 sur-
R

if there is a strong side wind

if you have adopted a sporty driving style
R
with high cornering speeds or high rates of
acceleration
if you are predominantly driving at a speed
