3-1. Using the air conditioning system and defogger
■
Using the system in recirculated air mode
The windows will fog up more easily if the recirculated air mode is used for
an extended period.
■
Window defogger feature
Recirculated air mode may automatically be switched to outside air mode in
situations where the windows need to be defogged.
■
When outside air temperature approaches 32°F (0°C)
The air conditioning system may not operate even when is pressed.
■
When the indicator light on flashes
Press and turn off the air conditioning system before turning it on once
more. There may be a problem in the air conditioning system if the indicator
light keeps flashing. Turn the air conditioning system off and have it
inspected by your Toyota dealer.
■
When is selected for the air outlets used
For your driving comfort, air flowing to the feet may be warmer than air flow-
ing to the upper body depending on the position of the temperature setting.
■
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.
CAUTION
■
To prevent the windshield from fogging up
Do not set the air outlet selection 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.
