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 sometimes there may be a small amount of
water dripping underneath the vehicle while idling or
after turning off the engine. This is normal.
9(Fan): Turn the center knob on the control panel to
control the fan speed. Turn the knob clockwise or
counterclockwise to increase or decrease the fan speed.
9(Off): Turn the center knob to this position to turn
the fan off. With the fan off, you may still experience
airflow from the system that increases with vehicle
speed depending on the mode and temperature settings.
Enable recirculation mode to stop this airflow from
occurring.
@ (Recirculation): Press the center of the fan
control knob to recirculate air inside the vehicle and
prevent outside air from coming in. It can be used
to prevent outside odors from entering the vehicle and
cool the air inside the vehicle more quickly. Press
this button to turn the recirculation mode on or off. An
indicator light on the button comes on to show that
the recirculation mode is activated.
Recirculation is available in the bi-level, and vent
modes. Recirculation is not available while in floor,
floor/defog and defrost mode. If recirculation is selected
in these modes, 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 will flash three times
and stay on to indicate that recirculation may not be
shut off.
The right knob on the control panel is used to direct the
airflow inside the vehicle. In-between modes are
available by moving the right control knob between
modes with symbols. The in-between mode is a
combination of the two modes that the control is
centered between.
Turn the right knob to select one of the following modes:
H (Vent): This mode directs air to the instrument
panel outlets.
