■Location of air outlets 
The air outlets and air volume 
changes according to the 
selected air flow mode. 
: Some models
■Adjusting the air flow direction and opening/closing the air 
outlets
Center outlets 
Direct air flow to the left or 
right, up or down. 
Close the vents.

■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. 
■ When driving on dusty roads 
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi- 
cle after closing the windows, it is recommended that the air intake mode be
set to outside air mode and the fan speed to any setting except off. 
■ Outside/recirculated air mode 
● Setting to the recirculated air mode temporarily is recommended in prevent- 
ing dirty air from entering the vehicle  interior and helping to cool the vehicle 
when the outside air temperature is high. 
● 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.

WARNING
■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 wind- 
shield 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.
