Operation Manual

The following information is displayed:
R
length of the journey since the last break.
R
the attention level determined by ATTEN-
TION ASSIST (Attention LevelAttention Level), dis-
played in a bar display in five levels from
high to low
R
If ATTENTION ASSIST is unable to calculate
the attention level and cannot issue a warn-
ing, the System SuspendedSystem Suspended message
appears. The bar display then changes the
display, e.g. if you are driving at a speed
below 37 mph (60 km/h) or above 124 mph
(200 km/h).
Activating ATTENTION ASSIST
X
Activate ATTENTION ASSIST using the on-
board computer (Y page 194).
The system determines the attention level
of the driver depending on the setting
selected:
Selection StandardStandard: the sensitivity with
which the system determines the attention
level is set to normal.
Selection SensitiveSensitive: 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).
Warning in the multifunction display
If fatigue or increasing lapses in concentra-
tion are detected, a warning appears in the
multifunction display: ATTENTION ASSISTATTENTION ASSIST
Take a Break!Take a Break!.
In addition to the message shown in the mul-
tifunction display, you will then hear a warn-
ing tone.
X
If necessary, take a break.
X
Confirm the message by pressing the a
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break and ATTENTION ASSIST
still detects increasing lapses in concentra-
tion, you will be warned again after
15 minutes at the earliest. This will only hap-
pen if ATTENTION ASSIST still detects typical
indicators of fatigue or increasing lapses in
concentration.
If a warning is output in the multifunction dis-
play, a service station search is performed in
COMAND. You can select a service station
and navigation to this service station will then
begin. This function can be activated and
deactivated in COMAND.
Blind Spot Assist
General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning display in the exterior mirrors
draws your attention to vehicles detected in
the monitored area. If you then switch on the
corresponding turn signal to change lanes,
you will also receive a visual and audible col-
lision warning.
Blind Spot Assist supports you from a speed
of approximately 20 mph (30 km/h).
Important safety notes
G
WARNING
Blind Spot Assist does not react to:
R
vehicles overtaken too closely on the side,
placing them in the blind spot area
R
vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
