Note: Recirculated air may turn off automatically (or be prevented from turning
on) in all airflow modes except MAX A/C to reduce risk of fogging. Recirculated
air may also turn on and off automatically in Panel or Panel and Floor airflow
modes during hot weather in order to improve cooling efficiency.
Passenger heated seat (if equipped): Switch the passenger heated seat
off and on. See Heated Seats (page 147). F
Temperature control: Controls the temperature of the airflow in your vehicle.
Adjust to select the desired temperature. G
MAX Defrost: Turn the temperature control dial all the way past the full heat
position to maximize defrosting. Outside air flows through the windshield vents,
fan automatically adjusts to the highest speed and the temperature dial returns
to the full heat position. You can use this setting to defog or clear a thin covering
of ice from the windshield. The heated rear window also automatically turns
on when you select MAX Defrost. H
Note: To prevent window fogging, you cannot select recirculated air when MAX
Defrost is on.
MAX A/C: Turn the temperature control dial all the way past the full cool
position to maximize cooling. Recirculated air flows through the instrument
panel vents, air conditioning automatically turns on, the fan automatically
adjusts to the highest speed and the temperature dial returns to the full cool
position. I
A/C: Press the button to switch air conditioning compressor on or off. Use air
conditioning with recirculated air to improve cooling performance and efficiency. J
Note: In certain conditions (such as when using Max Defrost), the air
conditioning compressor may continue to operate even after you switch off the
air conditioning with the A/C button.
Air distribution control: Press these buttons to switch airflow from the
windshield, instrument panel, or footwell vents on or off. The system can
distribute air through any combination of these vents. K
Note: At least one of these buttons remain on while the system is on.
Rear defrost and heated mirrors: Turns the heated mirrors off and on as well
as the heated rear window, if your vehicle has that feature. See Heated
Windows and Mirrors (page 139). L
