Air Conditioning
On hot days, open the windows long enough to let hot
air inside escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
The recirculation button, between the fan and temperature
knobs, allows the air inside your vehicle to be
recirculated. This setting helps to maximize your air
conditioner's performance and your vehicle's fuel
economy. This setting also cools the air the fatest and
can be used to keep unwanted odors and/or dust from
entering the vehicle. When using the air conditioner, turn
off recirculation after the vehicle reaches a comfortable
interior temperature. When the right knob on the control
panel is between HEATER and DEFROST, the
recirculation feature will not function.
The A/C button, between the temperature and mode
knobs, allows the air coming into your vehicle to be
cooled. This setting is useful for normal cooling on hot
days. When you use A/C with the recirculation button
pushed in, turn off recirculation as soon as the vehicle
reaches a comfortable interior temperature.
