BLIS* – Blind Spot Information System
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 after
starting the engine with one press on the
BLIS button.
When BLIS is deactivated, the lamp in the but-
ton goes out and a 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 on
the display and the indicator lamps in the door
panels flash 3 times. Press the READ button to
delete the text message. (For a description of
messages, see page 136).
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 have limitations similar to
those of the human eye, i.e. they do not
"see" as well e.g. in heavy snowfall, against
strong light or in thick fog.
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.
IMPORTANT
The lenses are electrically heated to melt ice
or snow. If necessary, brush snow away
from the lenses.
