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 travel-
ling.
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
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
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 vehicles. 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 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 cam-
eras have been blocked.
In both cases a message is shown in the
information display .
When driving in such conditions system
performance may be temporarily deterio-
rate and a text message is shown, see
page 148. If the message disappears auto-
matically then BLIS has returned to normal
functionality.
The BLIS cameras have limitations similar
to the human eye, i.e. they "see" worse in
heavy snowfall or thick fog for example.
