apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again. G

R release the parking brake.
R shift the automatic transmission out of the
parking position P.
R start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of

You can have current status information dis-
played in the assistance menu (Y page 235)
of the on-board computer.
X Select the Assistance display for ATTEN-
TION ASSIST using the on-board computer
(Y page 235).
The following information is displayed:
R 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 Suspended System 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 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 214
