06 Starting and driving
Blind Spot Information System BLIS (option)
When BLIS operates
The system is active when the car is driven at
a speed above 10 km/h.
Overtaking
The system is designed to react if you over-
take at a speed of up to 10 km/h faster than
the overtaken vehicle.
The system is designed to react if you are
overtaken by a vehicle travelling up to
70 km/h faster than your vehicle.
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 con-
ceal other vehicles in adjacent lanes. It can
06
prevent 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 de-
signed to detect motor vehicles such as cars,
trucks, buses and motorcycles.
In darkness the system reacts to the head-
lamps of surrounding vehicles. Vehicles with
headlamps that are switched off are not de-
130
tected by the system. This means for exam-
ple 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 bicycles or
mopeds.
The BLIS cameras can be disrupted by in-
tensive 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 on the
information display.
When driving in such conditions system
performance may be temporarily reduced
and a text message is shown, see
page 131.
If the message disappears automatically
then BLIS has returned to normal function-
ality.
The BLIS cameras have limitations similar
to the human eye, i.e. they "see" worse in
heavy snowfall or thick fog for example.
Activating/deactivating
Button for activating/deactivating.
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 by
pressing BLIS.
When BLIS is deactivated the light in the but-
ton 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 button to clear the text message. For
more information on messages, see page 47.
