still detects increasing lapses in concentra-
tion, you will be warned again after 15 minutes
at the earliest. This will only happen if ATTEN-
TION ASSIST still detects typical indicators of
fatigue or increasing lapses in concentration.
Vehicles with the COMAND multimedia
system: if a warning is output in the multi-
function display, a service station search is
performed in the multimedia system. You can
select a service station and navigation to this
service station will then begin. This function
can be activated or deactivated in the multi-
media system; see the Digital Operator's Man-
ual.
Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist (
Y
page 185) and Lane Keeping
Assist (
Y
page 186).
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 lane, you
will also receive an optical and audible warn-
ing.
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 vehi-
cle
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
sufficient distance to the side for other road
users and obstacles.

USA only:
This device has been approved by the FCC
as a "Vehicular Radar System". The radar
sensor is intended for use in an automotive
radar system only. Removing, tampering
with, or altering the device will void any war-
ranties, and is not permitted by the FCC. Do
not tamper with, alter, or use in any non-
approved way.
Any unauthorized modification to this device
could void the user’s authority to operate
the equipment.
Radar sensors
The radar sensors for Blind Spot Assist are
integrated into the rear bumper. Make sure
that the bumpers are free from dirt, ice or
slush. The sensors must not be covered, for
example by cycle racks or overhanging loads.
Following a severe impact or in the event of
damage to the bumpers, have the function of
the radar sensors checked at a qualified spe-
cialist workshop. Blind Spot Assist may no lon-
ger work properly.
Monitoring range of the sensors
In particular, the detection of obstacles can be
impaired if:
R
there is dirt on the sensors or anything else
covering the sensors
R
there is poor visibility, e.g. due to fog, heavy
rain or snow
R
a narrow vehicle traveling in front, e.g. a
motorbike or bicycle
R
the road has very wide lanes
R
the road has narrow lanes
R
you are not driving in the middle of the lane
R
there are barriers or other road boundaries
Vehicles in the monitoring range are then not
indicated.
Blind Spot Assist monitors the area up to 10 ft
(3 m) behind your vehicle and directly next to
it.
