If your vehicle does not have air conditioning, this is what your heating
system will look like.
Fan Lever
The top lever has five positions. To increase the air flow, move the lever
toward HIGH. To decrease the air flow, move
it
toward OFF.
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 four different 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.
Use this when you get fog or ice on the windshield.
HTR (Heater): Most of the air comes out near the floor. The rest comes out
from the defroster vents under the windshield and at the front side windows.
This is best for cold weather.
VENT: The air comes out at the vents on your instrument panel and at your
front side windows.
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.
