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
face 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
if you are predominantly driving at a speed
R
below 60 km/h or above 200 km/h
if the time has been set incorrectly
R
in active driving situations, such as when
R
you change lanes or change your speed
ATTENTION ASSIST is reset and starts
assessing your tiredness again when you con-
tinue your journey if:
you switch off the engine
R
you take off your seat belt and open the
R
driver's door, e.g. for a change of drivers or
to take a break
