BLIS is activated when the engine is started.
The indicator lamps in the door panels flash
three times when BLIS is activated.
The system can be deactivated/activated
when the engine is started by pressing the
BLIS button.
When BLIS is deactivated the light in the button
goes out and a text message is shown on the
dashboard display.
When BLIS is activated the light in the button
illuminates, a new text message is shown on
the display and the indicator lamps in the door
panels flash three times. Press the READ but-
ton to clear the text message. For more infor-
mation on messages, see page 119.
When BLIS operates
The system operates when the car is driven at
a speed above 10 km/h.
Overtaking
The system is designed to react if:
•
you overtake another vehicle at a speed of
up to 10 km/h faster than the other vehicle
•
you are overtaken by a vehicle travelling up
to 70 km/h faster than you are travelling.
WARNING
BLIS does not work in sharp bends.
BLIS does not work when the car is revers-
ing.
A wide trailer coupled to the car can conceal
other vehicles in adjacent lanes. It can pre-
vent the vehicle in the screened area from
being detected by BLIS.
Daylight and darkness
In daylight the system reacts to the shape of
the surrounding vehicles. The system is
designed to detect motor vehicles such as
cars, trucks, buses and motorcycles.
In darkness the system reacts to the head-
lamps of surrounding vehicles. If the head-
lamps of surrounding vehicles are not switched
on then the system does not detect the vehi-
cles. This means for example that the system
does not react to a trailer without headlamps
which is towed behind a car or truck.

BLIS* – Blind Spot Information System
WARNING
The system does not react to bicycles or
mopeds.
The BLIS cameras can be disrupted by
intensive light or when driving in the dark
when there are no light sources (e.g. street
lighting or other vehicles). The system may
then interpret the lack of light as if the cam-
eras have been blocked.
In both cases a message is shown in the
information display.
When driving in such conditions system
performance may be temporarily deterio-
rate and a text message is shown, see
page 179. If the message disappears auto-
matically then BLIS has returned to normal
functionality.
The BLIS cameras have limitations similar to
the human eye, i.e. they "see" worse in
heavy snowfall or thick fog for example.
Cleaning
In order to work most effectively the BLIS cam-
era lenses must be clean. The lenses can be
cleaned with a soft cloth or damp sponge.
Clean the lenses carefully so that they are not
scratched.
