0 (Defrost): This mode clears
the windshield of fog or frost
more quickly. Air is directed to the
windshield and side window
outlets. The system runs the air

# (Air Conditioning): Press to
turn the air conditioning system on
or off. An indicator light comes
on when the air conditioning
is turned on. This system cools and
dehumidifies the air entering the
vehicle.
The air conditioning will not function
if the fan is turned off. If air
conditioning is selected with fan off,
the indicator light flashes three
times and then turns off.
A slight change in engine
performance may occur when the
air conditioning compressor shuts off
and turns on again. This is normal.
The system is designed to make
adjustments to help with fuel
economy while still maintaining the
selected temperature.
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 when the
recirculation is on. This mode
recirculates and helps to quickly cool
the air inside the vehicle. It can be
used to prevent outside air and odors
from entering the vehicle.
Recirculation is available in the
bi-level and vent modes. This mode
cannot be selected while in the floor,
floor/defog or defrost modes. If you
try to select the recirculation mode,
the indicator flashes three times
indicating it is not available in that
mode. When the recirculation mode
is turned on, the air conditioning
turns on automatically.
When it is hot enough outside, the
recirculation mode may turn on
automatically to help improve cooling
performance. The indicator light will
be lit to show this mode is active. If
the recirculation button is pressed
while in this mode, the light flashes
three times and stays on to indicate
that recirculation may not be shut off.
