When does BLIS function
The system functions when your vehicle is
moving at speeds above 6 mph (10 km/h).
When you pass another vehicle:
The system reacts when you pass another
vehicle at a speed of up to 6 mph (10 km/h)
faster than that vehicle.
When you are passed by another
vehicle:
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 vehi-
cles. The system is designed to help detect
motor vehicles such as cars, trucks, buses,
motorcycles, etc.
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
mopeds.
•
BLIS does not react to vehicles that
are standing still.
•
The BLIS cameras have the same limi-
tation as the human eye. In other
words, their "vision is impaired" by
adverse weather conditions such as
heavy snowfall, intense light directly
into the camera, dense fog, etc.
Limitations
In certain situations, the BLIS indicator light(s)
may illuminate even when there are no other
vehicles in the area monitored by the system.

Blind Spot Information System (BLIS)*
NOTE
If the BLIS indicator lights illuminate occa-
sionally even when there are no other vehi-
cles in the blind area, this does not indi-
cate a fault in the system.
In the event of a fault, Blind spot syst.
Service required will be displayed.
The following are several examples of situa-
tions in which the BLIS indicator light(s) may
illuminate even when there are no other vehi-
cles in the area monitored by the system.
