Heater/Air Conditioning Controls
If your vehicle has air conditioning, your heatedair
conditioning controls will look like this.
Before using your vehicle's air conditioning, open the
windows to clear the vehicle of hot air.
Fan Knob
The knob on the left side of the heating system control
panel controls the fan speed. The knob has four speed
positions. To increase airflow, move the knob toward
HI. To decrease airflow, move it toward LO. To turn the
fan off, move the mode knob on the far right to OFF.
Temperature Knob
The middle knob on the control panel lets you select the
relative temperature of the air flowing into the passenger
area of your vehicle. This knob will allow you to adjust
the relative air temperature independently of the
function knob setting. Move the knob toward the red
area for warmer air. Move the
knob
toward the blue area
for cooler air.
Mode Knob
The right knob on the control panel changes the
heatedair conditioning setting.
MAX A/C: Move 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,
move the knob to the right to place the air conditioning
system in the A/C mode.
