06 Starting and driving
Blind Spot Information System*
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
*
172
Option/accessory, for more information, see Introduction.
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.
Cleaning the BLIS camera lenses
In order to function optimally, the BLIS cam-
era lenses must be kept clean. They can be
wiped clean with a soft cloth or wet sponge.
CAUTION
•
Clean the lenses carefully to avoid
scratching.
•
The lenses are electrically heated to
help melt ice or snow. If necessary,
gently brush away snow from the len-
ses.
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.
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.
Blind spot syst.
In the event of a fault,
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.
