■

For quick cooling (vehicles with an air conditioning system)

Turn the 

 dial to the “MAX A/C” position and select the recirculated air

mode.

■

Fogging up of the windows

●

Vehicles  with  the 

  button:  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 windshield effectively.

●

Vehicles with the 

 button: 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, set the out-
side/recirculated air mode button to the recirculated air mode. This is effective
in  preventing  outside  air  from  entering  the  vehicle  interior.  During  cooling
operation, setting the recirculated air mode will also cool the vehicle interior
effectively.

■

When the outside temperature is low (vehicles with the 

 button)

The air conditioning system 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.

WARNING

■

To prevent the windshield from fogging up

●

Do not set the air outlet selector dial 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 outside rear view mirror
defoggers are on.

NOTICE

■

To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.

●

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.

●

Engine speed controlled to restrict heating/cooling capacity.

●

Outside/recirculated  air  mode  may  automatically  switch  depending  on  the
temperature setting or the inside temperature. 

●

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. (
