Upon activation, the indicator lamps in the door
panels flash 3 times.
The system can be deactivated/activated
when the engine is started by pressing the
BLIS button.
When BLIS is deactivated, the lamp in the but-
ton goes out and a text message is shown in
the instrument panel display.
When BLIS is activated the light in the button
04
illuminates, a new text message is shown and
the indicator lamps in the door panels flash
3 times. Press the READ button to clear the
text message. For more information on mes-
sages, see page 118.

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.
WARNING
The system does not react to cyclists or
moped riders.
The BLIS cameras may have problems in
conditions with intense light or when driving
in the dark with no light sources (e.g. road-
way lighting or other vehicles). The system
may interpret the lack of lights as a blocked
camera or cameras.
In either case, a message appears on the
information display.
When driving in such conditions, system
performance may be temporarily poorer and
a text message is shown; see page 187. If
the message disappears automatically, it
indicates that BLIS has resumed normal
function.
The BLIS cameras have limitations similar to
those of the human eye, i.e. they do not
"see" as well in e.g. heavy snowfall or thick
fog.
