(Floor): In this mode most of the airflow comes
through the floor outlets. The rest of the air comes
through the windshield and side window vents. Set the
center knob to the desired temperature for comfort.

the floor outlets and the windshield defroster vent. The
air conditioning compressor will run automatically in
this mode when it is needed to help dry the air in
the vehicle.
(Front Defroster): This mode directs most of the
airflow through the windshield defroster vent. Some of
the air goes to the floor outlets. The air conditioning
compressor will run automatically in this mode when it
is needed to help dry the air in the vehicle.

A/C (Air Conditioning): Press A/C to operate the
air conditioning. The indicator light above the button
will glow when the button is pressed to indicate that the
air conditioning system has been turned on. The fan
knob must be set to a speed for the air conditioning
to operate.
Air Conditioning
The air conditioner and heater work best if you keep
your windows closed while using them. Your vehicle
also has the flow
-through ventilation system described
later in this section.
For normal cooling on hot days, use the vent mode with
the temperature knob in the blue area and the A/C
indicator light glowing. The system will bring in outside
air and cool it.
On very hot days, begin by opening the windows long
enough to let hot inside air escape. This reduces the time
it takes for your vehicle to cool down, which should
help fuel economy.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use bi
-level mode with the temperature knob in
the middle and the A/C indicator light glowing. The
system will bring in outside air and direct slightly
warmer air to your lower body.
