3966-1. Using the air conditioning system and defogger
3To stop the operation, press
the “OFF” switch.
If the fan speed setting or air
flow modes are operated, the
automatic mode indicator goes
off. However, automatic mode
for functions other than that
operated is maintained.
■Using automatic mode
Fan speed is adjusted automati-
cally according to the temperature
setting and the ambient conditions.
Therefore, the fan may stop for a
while until warm or cool air is ready
to flow immediately after the auto-
matic mode switch is pressed.
■Windshield fog d etection func-
tion
When automatic mode is set, the
humidity sensor detects fog on the
windshield and controls the air con-
ditioning system to prevent fog.
This function automatically con-
trols the air conditioning airflow
so that priority is given to the
front seats. When the front pas-
senger seat is not occupied, air-
flow may switch to only the
driver’s seat. Unnecessary air
conditioning is suppressed, con-
tributing to increased fuel effi-
ciency.
Front seat concentrated airflow
mode operates in the following
situations.
 No passengers are detected
in the rear seats 
The windshield defogger is
not operating
While operating, illumi-
nates.
■Manually turning front seat
concentrated airflow mode
on/off
In front seat concentrated air-
flow mode, directing airflow to
the front seats only and to all
seats can be switched via switch
operation. When the mode has
been switched manually, auto-
matic airflow control stops oper-
ating.
Press on the air condition-
ing operation panel and switch
the airflow.
 Indicator illuminated: Airflow
to the front seats only
 Indicator off: Airflow to all the
seats
■Operation of automatic airflow
control
●In order to maintain a comfortable
interior, airflow may be directed to
seats without passengers immedi-
ately after the hybrid system is
started and at other times depend-
ing on the outside temperature.
●After the hybrid system is started,
if passengers move around inside
or enter/exit the vehicle, the sys-
tem cannot accura tely detect the
presence of passengers and auto-
matic airflow co ntrol will not oper-
ate.

WARNING
■To not interrupt the wind-
shield defogger from operat-
ing
Do not place anything on the
instrument panel which may cover
the air outlets. Otherwise, air flow
may be obstructed, preventing the
windshield defoggers from defog-
ging.
NOTICE
■Humidity sensor
In order to detect fog on the wind-
shield, a sensor which monitors
the temperature of the windshield,
the surround humidity, etc. is
installed.
Follow these points to avoid dam-
aging the sensor:
●Do not disassemble the sensor
●Do not spray the glass cleaner
on the sensor or subject it to
strong impacts

Maintenance and care
■Front side windows water-
repellent coating (except quar-
ter window)
●The following precautions can
extend the effectiveness of the
water-repellent coating.
• Remove any dirt, etc., from the front side windows regularly.
• Do not allow dirt and dust to accu- mulate on the windows for a long
period. Clean the windows with a
soft, damp cloth as soon as possi-
ble.
• Do not use wax or glass cleaners
that contain abrasives when
cleaning the windows.
• Do not use any metallic objects to
remove condensation build up.
■Brake pads and calipers
Rust may form if the vehicle is
parked with wet brake pads or disc
rotors, causing them to stick. Before
parking the vehicle after it is
washed, drive slow ly and apply the
brakes several times to dry the
parts.
■Bumpers
Do not scrub with abrasive cleaners.
■Plated portions
If dirt cannot be removed, clean the
parts as follows:
●Use a soft cloth dampened with
an approximately 5% solution of
neutral detergent and water to
clean the dirt off.
●Wipe the surface with a dry, soft
cloth to remove any remaining
moisture.
●To remove oily deposits, use alco-
hol wet wipes or a similar product.
WARNING
■When washing the vehicle
Do not apply water to the inside of
the engine compartment. Doing
so may cause the electrical com-
ponents, etc. to catch fire.
■When cleaning the windshield
(vehicles with rain-sensing
windshield wipers)
Set the wiper switch to off.
If the wiper switch is in “AUTO”,
the wipers may operate unexpect-
edly in the following situations,
and may result in hands being
caught or other serious injuries
and cause damage to the wiper
blades.
Off
AUTO
●When the upper part of the
windshield where the raindrop
sensor is located is touched by
hand
●When a wet rag or similar is
held close to the raindrop sen-
sor
●If something bumps against the
windshield
●If you directly touch the raindrop
sensor body or if something
bumps into the ra indrop sensor
■Precautions regarding the
exhaust pipes
Exhaust gasses cause the
exhaust pipes to become quite
hot.
When washing the vehicle, be
careful not to touch the pipes until
they have cooled sufficiently, as
touching hot exhaust pipes can
cause burns.
