If ATTENTION ASSIST detects fatigue or
increasing lapses in concentration on the part
of the driver, it suggests taking a break.
G
Warning!
The ATTENTION ASSIST is only an aid to the
driver. It might not recognize fatigue or
increasing inattentiveness in time or fail to
recognize them at all. The system cannot
substitute a rested and attentive driver.
Fatigue can cause you to recognize dangers
too late, to misjudge potential dangers, or to
react slower. Therefore, make sure to be
rested before and during your trip. Take rests
early enough and regularly, especially during
long trips. Failure to do so could cause you to
recognize dangers too late which could result
in an accident and serious injury to you and/
or others.
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 predominantly drive at speeds under
50 mph (80 km/h) or over 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

On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you

concentration, you will be warned again after
15 minutes at the earliest.
ATTENTION ASSIST is reset when you
continue your journey; it reassesses your
tiredness if:

you switch off the engine.
R
you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
