If your vehicle has air conditioning, your heater/air
conditioning controls will look like this.

Before using your vehicle’s air conditioning, open the
windows to clear the vehicle of hot air.

The knob on the left side of the heating system control
panel regulates the fan speed. The knob has four speed
positions. To increase airflow, turn the knob toward HI.
To decrease airflow, turn it toward LO. To turn the fan
off, turn the mode knob on the far right to OFF.

The middle knob on the control panel lets you select the 
temperature of the air flowing into the passenger 
compartment of your vehicle. This knob will allow you to 
adjust the air temperature independently of the function knob 
setting. Turn the knob toward the red area for warmer air. 
Turn the knob toward the blue area for cooler air.

The right knob on the control panel changes the
heater/air conditioning setting.

MAX A/C: Turn the right knob to MAX A/C for
maximum cooling. This setting puts the system in the
recirculation mode and helps to maximize your air
conditioner’s performance and your vehicle’s fuel
economy. This setting also cools the air the fastest. After
the vehicle’s interior reaches a comfortable temperature,
turn the knob clockwise to place the air conditioning
system in the A/C mode.
