System function in daylight and
darkness
Daylight
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
Darkness
In darkness the system reacts to the headlamps
of surrounding vehicles. If its headlamps are
not switched on then the system does not detect
the vehicle. This means for example that the
system does not react to a trailer without
headlamps which is towed behind a car or
truck.
Cleaning
In order to work most effectively the BLIS
camera 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.

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
cameras have been blocked.
In both cases a message is shown in the
dashboard display.
When driving in such conditions the
system can be temporarily switched off
(see the information to the right).
When the text message has faded the
system returns to full functionality.
· The BLIS cameras have the same limita-
tions as the human eye, i.e. they "see"
worse in heavy snowfall or thick fog for
example.
Deactivating and reactivating BLIS
· BLIS is activated automatically each time
the ignition is switched on. The indicator
lamps in the door panels flash three times
when the ignition is switched on.
· The system can be switched off by pressing
the BLIS button in the switch panel in the
centre console (see illustration above). The
LED in the button goes out when the
system is switched off and a text message is
shown in the dashboard display.
· BLIS can be reactivated by pressing the
button. An LED in the button then lights, a
new text message is shown in the display
and the indicator lamps in the door panels
flash three times. Press the READ button,
see page 37, to clear the text message.
