HeatingAir Conditioning System
PO451
If your vehicle has air conditioning, your heating/air conditioning system will
look like this.
Before using your vehicle's air conditioning, open the windows to clear the
vehicle of hot air. Close the windows when using the system.
Fan Lever
The top lever has five positions. To increase the air flow, move the lever
toward HIGH.
Temperature Lever
The left lever lets you select the temperature of the air flowing into your
vehicle. Move the lever up for warmer air. Move the lever down for cooler air.
Function Lever
The right lever can be moved to seven different heating and air conditioning
functions.
Defrost: The setting with the defrost symbol operates the defroster. Most of
the air comes out near the windshield, with some going to the floor vents
and side window defrost vents. Use this when you get fog or ice on the
windshield.
BLEND: With this setting, the heated outside air comes out between the
heater vents and defroster vents, with some air coming through the side
vents. Adjust the temperature lever for warmer or cooler air.
