ATTENTION ASSIST
Important safety notes
ATTENTION ASSIST is only an aid. It cannot
always detect fatigue or lapses in concentra-
tion until too late or not at all. The system is
not a substitute for a well-rested and atten-
tive driver.
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 80 km/h
to 180 km/h range.
If ATTENTION ASSIST detects typical indica-
tors of fatigue or increasing lapses in con-
centration on the part of the driver, it sug-
gests taking a break.
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-related parameters, e.g. time of
day, 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 sur-
face 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 80 km/h or faster than 180 km/h
R
if you are currently using COMAND Online
or making a telephone call with COMAND
Online
R
if the time has been set incorrectly
R
in active driving situations, such as when
you change lanes or change your speed
