ATTENTION ASSIST
Important safety notes
ATTENTION ASSIST helps yo uduring long,
monotonous journeys, such as on highways .Itis
active in the rang ebetween 50 mph (80 km/h)
and 112 mph (180 km/h).
If ATTENTION ASSIST detects typica lindicators
of fatigueori ncreasing lapsesinc oncentration
on the part of the driver, it suggests yo utake a
break.
ATTENTION ASSIST assesses your level of fati-
gueorl apsesinc oncentration by taking the fol-
lowing criteria into account:
Ryour personald riving style, e.g. steering char-
acteristics
Rjourney details, e.g. time of daya nd length of
journey The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or not
occurata
ll:
Rif the roadc ondition is poor, e.g. if the surface
is uneven or if there are potholes
Rif there is astrong sid ewind
Rif yo uhavea doptedas porty driving styl ewith
hig hc ornering speeds or hig hrate sofa ccel-
eration
Rif yo uare predominantly driving slowe rthan
50 mph (80 km/h )orfaster than 112 mph
(180 km/h)
Rif yo uare currently using COMAND or making

Rif the time has bee nset incorrectly
Rin active driving situations, such as whe nyou
chang elan es or chang eyours peed
ATTENTION ASSIST is only an ai dtothe driver. It
might not always recognize fatigueori ncreasing
inattentiveness in time or fai ltorecognize them
at all. The system is not asubstitute for awell-
resteda nd attentive driver.

Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist (Ypage 159) and Lane Keeping
Assist (Ypage 161).
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. Awarning display in the exterior mirrors
draws your attention to vehicles detected in the
monitored area. If you then switch on the cor-
respondingt urn signal to change lane, you will
also receive an optical and audible warning.
Blind Spot Assist supports you from aspeed of
approximately 20 mph (30 km/h).
For Blind Spot Assist to assist you, the radar
sensor system must be operational.
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 alarge speed
differential and overtake your vehicle
As aresult, Blind Spot Assist may not give
warnings in such situations .There is arisk of
an accident.
Always observe the traffic conditions care-
fully, and maintain asafe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitut efor attentive driving. Always ensure that there is
sufficientd
istancetothe 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 automotiv eradar
system only. Removing, tamperin gwith, or
altering the device will void any warranties,
and is not permitted by the FCC. Do not tam-
per with, alter, or use in any non-approved
way.
An yu nauthorized modification to this device
could void the user’s authority to operate the
equipment.
Radar sensors
The radar sensor sfor Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the bumpers are free from dirt, ice or slush. The
sensor smust not be covered, for example by
cycle racks or overhangin gloads. Following a
severe impact or in the event of damage to the
bumpers, have the function of the radar sensors
checked at aqualified specialist 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 sensor soranything else
coveringt he sensors
Rthere is poor visibility, e.g. due to fog, heavy
rain, snow or spray
Rthere are narrow vehicles, e.g. motorcycles or
bicycles
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 other road boundaries
Vehicles in the monitoring range are then not
indicated.
Driving systems159

Blind Spot Assist monitors the areaupto10ft
(3.0 m)behind your vehicle and directly nex tto
your vehicle, as shown in the diagram. For this
purpose, Blind Spot Assist uses radar sensor sin
the rear bumper.
If the lanes are narrow, vehicles driving in the
lane beyond the lane nex ttoyour vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if ther eare vehicles driving at the inner
edge of their lanes.
Due to the natur eofthe system:
Rwarning smay be issued in error when driving
close to crash barriers or similar solid lane
borders.
Rwarning smay be interrupted when driving
alongside long vehicles, e.g. trucks, for apro-
longed time.
Indicator and warning display
