Important safety notes
ATTENTION ASSIST is only an aid. It may not
always detect fatigue or lapses in concentra-
tion until too late, or may not detect them at
all. The system is not a substitute for a well-
rested and attentive driver.
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or
not occur at all:
R
if the length of the journey is less than
approximately 30 minutes
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 at a speed
below 60 km/h or above 200 km/h
R
if you are driving with the active Steer
Assist of DISTRONIC PLUS
R
if the time has been set incorrectly
R
in active driving situations, such as when
you change lanes or change your speed
ATTENTION ASSIST is reset and starts
assessing your tiredness again when you con-
tinue your journey 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
Displaying the attention level
You can have current status information dis-
played in the assistance menu (
Y
page 257)
of the on-board computer.
X
Select the assistance graphics display for
ATTENTION ASSIST using the on-board
computer (
Y
page 256).
The following information is displayed:
R
the length of the journey since the last
break
R
the attention level determined by ATTEN-
TION ASSIST, displayed in a bar display in
five levels from high to low
R
if ATTENTION ASSIST is unable to calculate
the attention level and cannot output a
warning, the System passive System passive message
appears. The bar display then changes the
display, e.g. if you are driving at a speed
below 60 km/h or above 200 km/h.
Activating ATTENTION ASSIST
X
Activate ATTENTION ASSIST using the on-
board computer (
Y
page 259).
The system determines the attention level
of the driver depending on the setting
selected:
Standard selected: the sensitivity with
which the system determines the attention
level is set to normal.
Sensitive selected: the sensitivity is set
higher. The attention level detected by Atten-
tion Assist is adapted accordingly and the
driver is warned earlier.
When ATTENTION ASSIST is deactivated, the
é symbol appears in the multifunction
display in the assistance graphic display.
When ATTENTION ASSIST has been deactiva-
ted, it is automatically reactivated after the
engine has been stopped. The sensitivity
selected corresponds to the last selection
activated (standard/sensitive).
