ATTENTION ASSIST
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the range between 50 mph
(80 km/h) and 112 mph (180 km/h).
If ATTENTION ASSIST detects typical
indicators of fatigue or increasing lapses in
concentration on the part of the driver, it
suggests you take 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.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
R
your personal driving style, e.g. steering
characteristics
R
journey details, e.g. time of day and length
of journey
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
R
if the road condition is poor, e.g. if the
surface is uneven or if there are potholes
R
if there is a strong side wind
R
if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R
if you are predominantly driving slower
than 50 mph (80 km/h) or faster than
112 mph (180 km/h)
R
if you are currently using COMAND or
making a telephone call with it
R
if the time has been set incorrectly
R
in active driving situations, such as when
you change lanes or change your speed
