system's cameras are obscured then the
BLIS indicator lamp flashes and a message is
shown in the combined instrument panel. In
such cases, check and clean the lenses.
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.
The following illustrations show examples of
situations where the BLIS indicator lamp may
illuminate even if there is no other vehicle
within the blind spot.
If necessary, the system can be switched off
temporarily, see "Activate/deactivate BLIS"
above.
Overtaking
The system is designed to react if:
WARNING
The system does not react to cyclists or
moped riders.
you overtake another vehicle at a speed
of up to 10 km/h (6 mph) faster than the
overtaken vehicle
•
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.
Reflection from shiny wet road surface.
you are overtaken by a vehicle travelling
up to 70 km/h (43 mph) faster than you
are travelling.
•
Limitations
WARNING
In some situations the BLIS indicator lamp
may illuminate despite there being no other
vehicle within the blind spot.
BLIS does not work in sharp bends.
BLIS does not work when the car is
reversing.
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.
NOTE
Own shadow on large light smooth surface, e.g.
noise barrier or concrete road surface.
If the BLIS indicator lamp illuminates on
isolated occasions despite there being no
other vehicle within the blind spot then this
does not mean that a fault has arisen in
the system.
07
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 the event of a fault in the BLIS system
the display shows the text BLIS Service
required.
