indicator light will turn off.
Touch AUTO to return to automatic
operation and the air conditioner
runs automatically as needed. The
A/C will return to ECO a/c operation.

@:Press to turn on recirculation.
An indicator light comes on. Air is
recirculated to quickly cool the
inside of the vehicle or to reduce the
entry of outside air and odors. If selected during cool or cold
weather, the windshield and
windows may fog. Turn off
recirculation to help clear the
windshield and windows.
If equipped, the Air Quality Sensor
may operate the recirculation mode
automatically. See
“Climate and Air
Quality” underVehicle
Personalization 0138.
Auto Defog : If equipped, the
climate control system may have a
sensor to automatically detect high
humidity inside the vehicle. When
high humidity is detected, the
climate control system may adjust to
outside air supply and turn on the
air conditioner. The fan speed may
slightly increase to help prevent
fogging. If the climate control
system does not detect possible
window fogging, it returns to normal
operation.
To turn Auto Defog off or on, see
“Climate and Air Quality” under
Vehicle Personalization 0138.

defogger on or off. An indicator light
on the button comes on to show that
the rear window defogger is on. The
rear window defogger only works
when the engine is running. It turns
off when the ignition is placed in the
ACC/ACCESSORY or LOCK/OFF
position.
The rear window defogger can be
set to automatic operation. See
“Climate and Air Quality” under
Vehicle Personalization 0138.
When Auto Rear Defog is selected,
the rear window defogger turns on
automatically when the interior
temperature is cold and the outside
temperature is about 4 °C (40 °F)
and below. The auto rear defogger
turns off automatically after about
10 minutes, or after five minutes if
the outside temperature is not
as cold.
The upper gridlines on the rear
window are antenna lines and are
not intended to heat when the
defogger is activated.
