Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
ambient conditions. As a result, the following may occur:
Immediately after the button is pressed, the fan may stop for a while
until warm or cool air is ready to flow.
Cool air may flow to the area around the upper body when the heater is
on.
Humidity sensor (if equipped)
Using the system in recirculated air mode
The windows will fog up more easily if recirculated air mode is used.
Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched to
in accordance with the temperature setting and the inside temperature.
A sensor, which detects humidity inside
the vehicle and the temperature of the
windshield, is provided to detect fog on
the front windscreen. Due to the sensor,
when automatic mode is set the air condi-
tioning may make the following controls:
Changing the amount of air flow
Changing the amount of air introduced
from outside when in outside air mode
with the air vents in the position
Changing the settings of the air vents to
when the is set

Window defogger feature
Recirculated air mode may automatically switch to (outside air)
mode in situations where the windows need to be defogged.
Pollen removal mode
In order to prevent the windshield from fogging up when the outside air
is cold, the following may occur:
• Outside air mode does not switch to (recirculated air) mode.
• The air conditioning system operates automatically.
• The operation cancels after 1 minute.
In rainy weather, the windows may fog up. Press .
When outside air temperature is below 0 C (32 F)
The cooling and dehumidification function may not operate even when
is pressed.
Operation of the air conditioning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows
to prioritize fuel efficiency:
Engine speed and compressor operation controlled to restrict heating/
cooling capacity
Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
Adjust the fan speed
Turn off Eco drive mode
Customize the air conditioning control of Eco drive mode. (P. 667)

Air conditioning odors
During use, various odors from inside and outside the vehicle may enter
into and accumulate 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 delayed for a short period of
time immediately after the air conditioning system is started in AUTO
mode.
Customization
Settings (e.g. enable/disable automatic operation of the air conditioning
compressor when the “AUTO” switch ON) can be changed.
(Customizable features P. 667)
CAUTION
To prevent the windshield from fogging up
Do not use
during cool air operation in extremely humid weather.
The difference 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.

CAUTION
When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
When cleaning the windshield (vehicles with rain-sensing windshield wip-
ers)
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 sensor
If something bumps against the windshield
If you directly touch the raindrop sensor body or if something bumps into
the raindrop sensor
Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has
cooled sufficiently, as touching a hot exhaust pipe can cause burns.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the
wipers may operate unexpectedly in the
following situations, and may result in
hands being caught or other serious inju-
ries and cause damage to the wiper
blades.
