ATTENTION ASSIST
Important safety notes ATTENTION ASSIST is only an aid to the
driver. It might no
talways recognize fatigue
or increasing inattentiveness in time or fail to
recognize the matall. The system is not a
substitute for a well-rested and attentive
driver.
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.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria int oaccount:
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 sid ewind
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 Warning and display messages in the
multifunction display X
Activate ATTENTION ASSIST using the on-
board computer (Y page 214).
If ATTENTION ASSIST is active, you will be
warned no sooner than 20 minutes after your
journey has begun. You the nhear an
intermittent warning tonet wice and the
Attention Assist: Drowsiness detected message appears in the
multifunction display.
X If necessary, take a break.
X Press the 000Bbutton to confirm the
message.
On long journeys, take regular breaks in good
time to allow yourself to res tproperly. If you
do not take a break, you will be warned again
after 15 minutes at the earliest. The
precondition for this is that
ATTENTION ASSIST still detects typical
indicators of fatigue or increasing lapses in
concentration.
ATTENTION ASSIST is reset when you
continue yourj ourney and starts assessing
your tiredness again if:
R 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
to take a break.
The assistance graphic shows the 0002
symbol when ATTENTION ASSIST is
deactivated (Y page 213). Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y
page 193) and Lane Keeping
Assist (Y page 194). 192
