# (Air Conditioning): Press to turn the air conditioning
(A/C) compressor on and off. An indicator light comes on
to show that the air conditioning is on.
If this button is pressed when the air conditioning
compressor is unavailable, the indicator flashes three
times and then turns off. If the air conditioning is on and
the outside temperature drops below a temperature
which is too cool for air conditioning to be effective, the air
conditioning light turns off to show that the air
conditioning mode has been canceled.
On hot days, open the windows long enough to let hot
inside air escape. This helps to reduce the time it takes
for the vehicle to cool down. It also helps the system to
operate more efficiently.
The air conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine. This is
normal.
@ (Recirculation): Press to turn the recirculation
mode on or off. An indicator light comes on to show that
the recirculation is on.
This mode recirculates and helps to quickly cool the air
inside the vehicle. It can be used to help prevent
outside air and odors from entering the vehicle.
The recirculation mode cannot be used with floor, defog,
or defrost modes. If recirculation is selected with one of
those modes, the indicator light flashes three times and
then turns off. The air conditioning compressor also
comes on when this mode is activated. While in
recirculation mode the windows may fog when the
weather is cold and damp. To clear the fog, select either
the defog or defrost mode and increase the fan speed.
The recirculation mode can also be turned off by turning
off the ignition.
REAR: For vehicles with the rear heat and air
conditioning controls. Press to turn the rear climate
control system on or off. See Rear Air Conditioning and
Heating System and Electronic Climate Controls on
page 3-32.
