characteristics
R journey details, e.g. time of day and length
of journey

General notes The Lane Trackin

Spot Assist (Y page 184) and Lane Keeping
Assist (Y page 186).
Blind Spot Assist General notes
Blind Spot Assist uses
aradar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from aspeed of
approximately 20 mph (30k m/h). Awarning
displa yinthe exterio rmirrors draws your
attention to vehicles detected in the 184
Driving systemsDriving and parking

monitored area
.Ifyou then switch on the
corresponding turn signa ltochange lanes,
you willa lsor eceive avisual and audible
collision warning. For this purpose, Blind Spot
Assist uses sensors in the rear bumper.
Important safety notes G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closel yonthe side,
placing them in the blind spot area
R vehicles which approach with alarg espeed
differential and overtake yourv ehicle
As aresult, Blind Spot Assist may not give
warnings in such situations. There is arisk of
an accident.
Always observe the traffic conditions
carefully, and maintain asafe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detec tsome vehicles and is no substitute for
attentive driving.
i USA only:
This device has been approved by the FCC
as a"Vehicular RadarS ystem". The radar
sensor is intended fo ruse 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.
Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired if:
R 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 an arrow 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 similarl ane borders
Vehicle sinthemonitorin grang eare then not
indicated. Blin
dSpotA ssist monitors the area up to
10 ft (3.0 m) behind your vehicle and directly
nex ttoy our vehicle, as shown in the diagram.
For this purpose, Blind Spot Assist uses radar
sensors in the rear bumper.
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:
R warnings may be issued in error when
driving close to crash barriers or similar
solid lane borders.
R warnings may be interrupted when driving
alongside particularly long vehicles, e.g.
trucks, for aprolonged time.
The two sensors for Blind Spot Assist are
integrated into the sides of the rear bumper.
Make sure that the bumper is free of dirt, ice
or slush in the vicinit yofthe sensors. For
example, the radar sensors must not be
covered by bicycle racks or overhanging
loads. Following asevere impact or in the Driving systems
