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 vehicles existence via
the outside rear view mirror indicator.

Approximately 0.5 m (1.6 ft.) to 3.5
m (11.5 ft.) from either side of the
vehicle*

WARNING
■Cautions regarding the use of the function
The driver is solely responsible for safe dr iving. Always drive safely, taking care to
observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a vehicle is in
a blind spot of the outside rear view mirrors or is approaching rapidly from behind into
a blind spot. Do not overly rely on the BSM function. As the function cannot judge if it is safe to change lanes, over reliance could lead to an accident resulting in death or seri-
ous injury.
As the system may not function correctly under certain conditions, the driver’s own visual confirmation of safety is necessary.

■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air mode.
●During use, various odors from inside and outside the vehicle may enter into and accu-
mulate in the air conditioning system. This may then cause odor to be emitted from the
vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode prior
to turning the vehicle off. • The start timing of the blower may be dela yed for a short period of time immediately
after the air conditioning system is started in automatic mode.

WARNING
■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.
●Do not touch the glass at lower part of the windshield or to the side of the front pillars
when the windshield wiper de-icer is on.
NOTICE
■To prevent 12-vol t battery discharge
Do not leave the air conditioni ng system on longer than necessary when the hybrid sys- tem is off.
●Do not place anything on the instrumentpanel which may cover th e air outlets. Other-
wise, air flow may be obstructed, preventing
