WARNING
■To prevent the windshield from fogging up
● Do not set to 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.
■ To prevent burns
● Vehicles with outside rear view mirror defoggers: Do not touch the rear
view mirror surfaces when the outsi de rear view mirror defoggers are on.
● Vehicles with windshield wiper de-icer: Do not touch the glass at lower part
of the windshield or the side of the front pillars when the windshield wiper
de-icer is on.
NOTICE
■ To prevent battery discharge
Do not leave the air conditioning syst em on longer than necessary when the
engine is not running.
● 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 defogging.

■Using automatic mode
Fan speed is adjusted automatically 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 is pressed.
■ Fogging up of the windows
● The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ Outside/recirculated air mode
● When driving on dusty roads such as tunnels or in heavy traffic, press .
This is effective in preventing outside air from entering the vehicle interior.
During cooling operation, setting the reci rculated air mode will also cool the
vehicle interior effectively.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
■ Operation of the air conditioning system in Eco drive mode (if equipped)
● In Eco drive mode, the air conditioning system is controlled as follows to pri-
oritize 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
• Adjust the temperature setting
■ When the outside temperature falls to nearly 0°C (32°F)
The dehumidification function may not operate even when is pressed.

■ 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 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.
• For some models: The start timing of the blower may be delayed for a
short period of time immediately after the air conditioning system is
started in automatic mode.
■ Air conditioning system operations when the engine is stopped due to
the Stop & Start system (vehicles with Stop & Start system)
When the engine is stopped due to Stop & Start system operations, the
automatic air conditioning cooling, heating and dehumidification functions
turn off and the fan speed is decreased according to the outside tempera-
ture etc. or air blowing stops. To stop the air conditioning system from turn-
ing off, press the Stop & Start cancel switch and refrain from using the Stop
& Start system.
■ An odor comes from the air conditioning system due to the Stop & Start
system operation (vehicles with Stop & Start system)
When the engine is stopped due to Stop & Start system operations, an odor
caused by moisture may be detected. This does not indicate a malfunction.
