rear window and to remove rain- 
drops, dew and frost from the out- 
side rear view mirrors. 
Press the rear window and outside  
rear view mirror defogger switch.
The defoggers will automatically turn off  
after a period of time.

from building up on the windshield  
and wiper blades. 
Press the windshield wiper de-icer  
switch.
The indicator   comes on when the  
windshield wiper de-icer is on. 
The windshield wiper de-icer will auto- 
matically turn off after a period of time.
■Fogging up of the windows
●The windows will easily fog up when  the humidity in the vehicle is high.  
Selecting “A/C” will dehumidify the air  from the outlets and defog the wind-shield effectively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recir-culated air mode is used.
■When driving on dusty roads 
Close all windows. If dust thrown up by  the vehicle is still drawn into the vehicle after closing the windows, it is recom- 
mended 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 pre- 
venting dirty air from entering the  vehicle interior and helping to cool the vehicle when the outside air tempera- 
ture is high.
●Outside/recirculated air mode may  automatically switch depending on the temperature setting or the inside tem- 
perature.
■When the outside temperature is  low 
The dehumidification function may not  
operate even when “A/C” is selected.

Interior features
■Ventilation and air conditioning  
odors
●To let fresh air in, set the air condition-
ing 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 occur-
ring: • It is recommended that the air condi-tioning 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 automatic mode.

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 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 the automatic mode  
switch is pressed. 
Cool air may blow around the upper  body even when the heater is on due to  
sunlight.
To turn on the “SYNC” mode, per- 
form any of the following proce- 
dures: 
 Press the “SYNC” mode switch.
WARNING
■To prevent the windshield from  fogging up 
Do not use the windshield defogger  
switch during cool air operation in  extremely humid weather. The differ-ence 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
●Do not touch the outside rear view  mirror surfaces, as they can become very hot and burn you.
●Vehicles with windshield wiper de-icer: Do not touch the glass at lower  
part of the windshield or to the side  of the front pillars when the wind-shield wiper de-icer is on.
NOTICE
■To prevent 12-volt battery dis-charge
