ATTENTION ASSIST
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the 37 mph (60 km/h) to
125 mph (200 km/h) range. If ATTEN-
TION ASSIST detects typical indicators of fati-
gue or increasing lapses in concentration on
the part of the driver, it suggests taking a
break.
Important safety notes
ATTENTION ASSIST is only an aid to the
driver. It might not always recognize fatigue
or increasing inattentiveness in time or fail to
recognize them at all. The system is not a
substitute for a well-rested and attentive
driver.

The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
Rif the length of the journey is less than
approximately 30 minutes
Rif the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
Rif there is a strong side wind
Rif you have adopted a sporty driving style
with high cornering speeds or high rates ofacceleration
Rif you are predominantly driving slower
than 37 mph (60 km/h) or faster than
125 mph (200 km/h)
Rif the time has been set incorrectly
Rin active driving situations, such as when
you change lanes or change your speed
ATTENTION ASSIST is reset when you con-
tinue your journey and starts assessing your
tiredness again if:
Ryou switch off the engine
Ryou take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break
Displaying the attention level
You can have current status information dis-
played in the assistance menu (

XIf necessary, take a break.
XConfirm the message by pressing thea
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.
Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist (
Ypage 213) and Lane Keeping
Assist (
Ypage 215).
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
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles 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
sufficient distance to the side for other road
users and obstacles.
iUSA 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
warranties, 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
longer work properly.

Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired if:
Rthere is dirt on the sensors or anything elsecovering the sensors
Rthere is poor visibility, e.g. due to fog, heavy
rain or snow
Ra narrow vehicle traveling in front, e.g. a
motorbike or bicycle
Rthe road has very wide lanes
Rthe road has narrow lanes
Ryou are not driving in the middle of the lane
Rthere are barriers or similar lane borders
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
your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may be
the case if the vehicles are driving on the inner
side of their lane. Due to the nature of the system:
Rwarnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders.
Rwarnings may be interrupted when driving
alongside particularly long vehicles, e.g.
trucks, for a prolonged time.
Warning display
:Warning display
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
When Blind Spot Assist is activated, indicator
lamp :in the exterior mirrors lights up yel-
low at speeds of up to 20 mph (30 km/h). At
speeds above 20 mph (30 km/h), the indica-
tor lamp goes out and Blind Spot Assist is
operational.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp :on the corre-
sponding side lights up red. This warning is
always emitted when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle,
the warning only occurs if the difference in
speed is less than 7 mph (12 km/h).
The yellow indicator lamp goes out if reverse
gear is engaged. In this event, Blind Spot
Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
