ATTENTION ASSIST
ATTENTION ASSIST helps you on long, monot-
onous journeys such as on motorways and
trunk roads. It is active at speeds between 80
and 180 km/h. If ATTENTION ASSIST detects
tiredness or increasing lapses in concentra-
tion on the part of the driver, it suggests a
break.
G
Risk of accident
ATTENTION ASSIST is only an aid and may
detect your tiredness or lapses in concentra-
tion too late or not at all. It is not a substitute
for a well rested and attentive driver.
Fatigue may cause you to recognise hazard-
ous situations too late, misjudge a situation
or react slower. For this reason, make sure
you feel rested before you begin driving and
during your journey. Always take breaks in
good time and regularly, especially during
long journeys. Otherwise, you may fail to rec-
ognise dangers in time, cause an accident and
injure yourself and others.
ATTENTION ASSIST assesses your level of
fatigue or increasing inattentiveness taking
into consideration the following criteria:
personal driving style, e.g. steering charac-
R
teristics
driving conditions, e. g. time, driving time

ATTENTION ASSIST's functionality is restric-
ted and warnings are delayed or do not
appear at all:

R
bumps or potholes

a high rate of acceleration
if you are predominantly driving slower
R
than 80 km/h or faster than 180 km/h
