faster than that vehicle.

cle:
04 The system reacts if your vehicle is passed
by another vehicle at a speed of up to 43
mph (70 km/h) faster than your vehicle.
WARNING
• BLIS does not function in sharp curves.
• BLIS does not function when your vehicle
is backing up.
• If you are towing a wide trailer, this may
prevent the BLIS cameras from detecting
other vehicles in adjacent lanes.
How BLIS functions in daylight and
darkness
Daylight
BLIS reacts to the shape of surrounding
vehicles. The system is designed to help
detect motor vehicles such as cars, trucks,
buses, motorcycles, etc.
158
Darkness
BLIS reacts to the headlights of surrounding
vehicles. In order to be detected by BLIS, a
vehicle in the blind area must have its head-
lights on. This means, for example, that the
system will not detect a trailer without head-
lights that is being towed behind a car or
truck.
WARNING
• BLIS does not react to cyclists or mo-
peds.
• BLIS does not react to vehicles that are
standing still.
• The function of the BLIS cameras may be
affected by intense light, or when driving at
night in areas where there are no external
sources of light (e.g., street lights, other ve-
hicles, etc.). In such cases, the system may
react as if the cameras were obscured.
• In both of the above mentioned condi-
tions, a message will appear in the informa-
tion display.
• When driving in such conditions, the sys-
tem's function will be limited or it may be
temporarily switched off. See page 159 for
instructions.
• When the message is no longer dis-
played, BLIS will return to normal function.
• The BLIS cameras have the same limita-
tion as the human eye. In other words, their
"vision is impaired" by adverse weather
conditions such as heavy snowfall, dense
fog, etc.
