Activating ATTENTION ASSIST
X
Activate ATTENTION ASSIST using the on-
board computer (Y page 236).
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
À symbol and OFF appear in the multi-
function display in the assistance display
when the engine is running.
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 Assist:Attention 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, you will be warned again
after 15 minutes at the earliest. This will only
happen if ATTENTION ASSIST still detects
typical indicators of fatigue or increasing lap-
ses in concentration.
Vehicles with COMAND: if a warning is
issued in the multifunction display, a service
station search is performed in COMAND. You
can select a service station and navigation to
this service station will then begin. This func-
tion can be activated and deactivated in
COMAND.
Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist (Y page 214) and Lane Keeping
Assist (Y page 216).
Blind Spot Assist
General notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from a speed of
approximately 20 mph (30 km/h). A warning
display in the exterior mirrors draws your
attention to vehicles detected in the moni-
tored area. If you then switch on the corre-
sponding turn signal to change lanes, you will
also receive an optical and audible collision
