The following information is displayed:
R the length of the journey since the last break.
R the attention level determined by ATTENTION
ASSIST ( Attention Level
Attention Level), 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 issue a warn-
ing, the System Suspended System Suspended message
appears. The bar display then changes what is shown, e.g. if you are driving at a speed below 37 mph (60 km/h) or above 125 mph
(200 km/h).
Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer (Y page 168).
The system determines the attention level of
the driver depending on the setting selected:
Selection of Standard
Standard: the sensitivity with
which the system determines the attention level
is set to normal.
Selection of Sensitive Sensitive: 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
00D7 symbol appears in the multifunction dis-
play in the Assistance display.
When ATTENTION ASSIST has been deactivated, it is automatically reactivated after the engine
has been stopped. The sensitivity selected cor-
responds to the last selection activated ( Stand‐
Stand‐
ard ard orSensitive
Sensitive ).
Warning in the multifunction display If fatigue or increasing lapses in concentration
are detected, a warning appears in the multi-
function display: ATTENTION ASSIST
ATTENTION ASSIST Take a Take a
Break!
Break! .
In addition to the message shown in the multi-
function display, you will then hear a warning
tone.
X If necessary, take a break.
X Confirm the message by pressing the 0076
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest. If you do not take a break and ATTENTION ASSIST still detects
increasing lapses in concentration, 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 increas-
ing 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. Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 155) and Lane Keeping
Assist (Y page 157).
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 cor-
responding turn signal to change lanes, you will also receive a visual warning and hear a warning
tone.
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.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is Driving systems
