flows in order to control the cabin tempera-
ture without blowing air directly on the
occupants. The upper vent system is useful when you
want the air conditioner to work quickly.
To turn the system off, touch the “Upper
Vent” key to turn the indicator light off.
Advanced Climate Control System
(if so equipped)
The Advanced Climate Control System
keeps the air inside of the vehicle clean,
using the automatic air circulation control
with the exhaust gas/outside odor detection
sensor and with ion control.
WAE0260X
“Auto Recirc” key:
Touch to turn on the automatic air
recirculation mode.
Plasmacluster®icon:
Indicates the Plasmacluster®ion emis-
sion status.
Plasmacluster
®and Plasmacluster®ion are
registered trademarks of Sharp Corporation.
Automatic air recirculation control with the
exhaust gas/outside odor detection sensor:
The Advanced Climate Control system
comes with an exhaust gas detection/out-
side odor sensor. When the automatic air
circulation control is activated, the sensor

detects odors outside the vehicle such as
pulp or chemicals, and exhaust gas such as
gasoline or diesel. When such odors or gases
are detected, the display and the system
automatically change from the fresh air
mode to the recirculation mode.
When the automatic air circulation control
mode is on, for the first 5 minutes, the air
recirculation mode is selected to prevent
dust, dirt and pollen from entering the
vehicle and to clean the air inside of the
vehicle.
After 5 minutes, the sensor detects exhaust
gas and automatically alternates between
the air recirculation mode and the fresh air
mode.
NOTE:
The automatic air recirculation mode can be
activated under the following conditions.
.The air flow control is not in the wind-
shield defrosting mode (the indicator
light on the “
” front defroster but-
ton is turned off).
. The outside temperature is approxi-
mately 32 °F (0 °C) or above.
Ion control:
The Advanced Climate Control system unit
generates highly concentrated Plasmaclus-
ter
®ions into the air blown from the
ventilators to reduce odor absorbed into the interior trim and to suppress airborne
bacteria. The high-density Plasmacluster
®
ions also have a proven skin moisture
preserving effect.
The Plasmacluster
®icon on the Climate
screen indicates the status of the Plas-
macluster
®ion emission from the system
and changes with the amount of the air flow.
REAR AUTOMATIC AIR CONDI-
TIONING SYSTEM
The front air conditioning system must be
turned on to activate the rear air condition-
ing system.
The rear air conditioning system can be
