areas.
The Blind spot detector uses radar sensors to
monitor the areas to the side and behind the
vehicle. The system does this by measuring
the vehicle's distance from other vehicles and
its speed differential. The blind spot detector
will not work at speeds of less than approx. 15
km/h (9 mph). The system uses optical sig-
Driver assistance systems
nals in the external rear view mirrors to notify
the driver.
Indication in the external rear view mirrors
The control lamp (expanded view) provides
an indication in the corresponding external
›››
mirror Fig. 271 regarding the traffic situa-
tion behind the vehicle, if it is deemed to be
critical. The control lamp of the left-hand ex-
ternal mirror A indicates the traffic situation to
the left of the vehicle, and the control lamp of
the right-hand external mirror B, indicates the
traffic situation to the right of the vehicle.
In the case of tinted windows or windows with
tinted film, the indications of the external mir-
rors may not be seen clearly or correctly.
Keep the external mirrors clean and free of
snow and ice, and do not cover them with ad-
hesives or other similar materials.
Radar sensors
The radar sensor are located on the left and
right of the bumper, and are not visible from
›››
the outside Fig. 272. The sensors detect an
area of approx. 20 metres behind the vehicle,
including the blind spots to the left and right
of the vehicle. The range to the sides of the
vehicle is roughly larger than the width of a
lane.
The lane width is not detected individually,
but is rather pre-configured in the system.
Thus if you are driving in wide lanes or in be-
tween two lanes, the indications may be in-
correct. Furthermore, the system can detect
vehicles driving in the lane next to you (if
there are any), and can also detect station-
ary objects such as dividers, and thus give an
incorrect indication.
