Starting and driving
BLIS (Blind Spot Information System) - option
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.
WARNING!
- BLIS does not work in sharp bends.
- BLIS does not work when the car is
reversing.
- A wide trailer coupled to the car can
conceal other vehicles in adjacent lanes. It
can prevent vehicles in the screened area
from being detected by BLIS.
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 on the
information display.
When driving in such conditions system
performance may be temporarily reduced
(see the information on the next page).
When the text message disappears 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.
IMPORTANT!
- The lenses are electrically heated to
melt ice or snow. If necessary, brush
snow away from the lenses.
