■Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature set-
ting and ambient conditions. As a result, the following may occur.
●The system may switch automatically to recirculated air mode when the
coolest temperature setting is selected in summer.
● Immediately after
  is pressed, the fan may stop for a while until
warm or cool air is ready to flow. 
● Cool air may flow to the area around the upper body when the heater is
on.
■ 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 switch to outside air mode in situa-
tions where the windows need to be defogged.
■ When outside air temperat ure 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 indi-
cator light continues to flash. Turn the air conditioning system off and have it
inspected by your Toyota dealer.
■ Windshield air flow button
When any of the following conditions occurs, the indicator light on the button
may flash and a motor sound may be heard. This does not indicate a mal-
function.
●The “ENGINE START STOP” switch is in ON mode (vehicles with smart
key system) or engine switch is in “ON” position (vehicles without smart
key system) after the battery is reconnected.
● Engine starting and stopping is repeated at short intervals.
● The engine is started with the low voltage battery.

Interior features
■Plasmacluster *
This air conditioning system adopts plasmacluster technology, which helps
to keep good air quality in the cabin by emitting positive and negative ions
through the driver's side vent.
A slight noise may be heard during operation. This is not a malfunction.
Also, static electricity may be discharged near the driver's side vent due to
the high voltage used to operate the system.
To clean the drive's side vent, turn the system off and wipe the vent using a
soft cloth.
*: Plasmacluster technology is manufactured under license from SHARP Corporation. “Plasmacluster ” is a trademark of the SHARP Corporation.
CAUTION
■ 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
windshield can cause the outer surface of the windshield to fog up, blocking
your vision.
■ Plasmacluster 
Do not disassemble or repair the system because it contains high voltage
parts. Call your Toyota dealer if the system needs repair.
NOTICE
■ To prevent battery discharge
Do not leave the automatic air conditioning system on longer than necessary
when the engine is stopped.
■ To prevent damage to the Plasmacluster
Do not insert anything into the driver's side vent, attach anything to it, or use
sprays around the drive's side vent. These things may cause the system not
to work properly.

Rear window and outside rear view mirror defoggers
■Outside rear view mirror defoggers (if equipped)
Turning the rear window defogger on will turn the outside rear view mirror
defoggers on.
■ When the indicator light on the sw itch flashes and a motor sound is
heard (vehicles with manual air conditioning)
If any of the following conditions occurs, it does not indicate a malfun\
ction.
● The engine switch is in “ON” position after the battery is reconnected.
● Engine starting and stopping is repeated at short intervals.
● The engine is started with the low voltage battery.
Clear the rear window using the defogger.

time. The operation time is
between 15 minutes and 1
hour depending on the ambient
temperature and vehicle
speed.
