The Blind Spot Monitor function uses radar sensors to detect vehicles that are
traveling in an adjacent lane in the area that is not reflected in the outside rear
view mirror (the blind spot), and advises the driver of the vehicle’s existence via
the outside rear view mirror indicator.
The areas that vehicles can be detected in are outlined below.
The range of the detection area
extends to:
Approximately 11.5 ft. (3.5 m) from
the side of the vehicle
The first 1.6 ft. (0.5 m) from the side of
the vehicle is not in the detection area
Approximately 9.8 ft. (3 m) from the

■Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
The Blind Spot Monitor function is a supplementary function which alerts the driver
that a vehicle is present in the blind spot. Do not overly rely on the Blind Spot Monitor
function. The function cannot judge if it is sa fe to change lanes, therefore over reliance
could cause an accident resulting in death or serious injury.
According to conditions, the system may not function correctly. Therefore the driver’s
own visual confirmation of safety is necessary.

your vehicle is necessary and be sure there are no pedestrians, other vehicles etc.
before backing up. Failure to do so could cause death or serious injury.
According to conditions, the system may not function correctly. Therefore the driver’s
own visual confirmation of safety is necessary.

■To prevent the windshield from fogging up
●Do not use during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outside air and that of the windshield can cause
the outer surface of the windshield to fog up, blocking your vision.
■To prevent burns
●Do not touch the rear view mirror surfaces when the outside rear view mirror defog-
gers are on.
●Vehicles with windshield wiper de-icer: Do not touch the glass at lower part of the
windshield or to the side of the front pilla rs when the windshield wiper de-icer is on.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the engine is
stopped.
●Do not place anything on the instrument
panel which may cover the air outlets. Other-
wise, air flow may be obstructed, preventing
the windshield defoggers from defogging.
