MAX: This setting recirculates much of the air inside your vehicle and sends through the instrument panel it outlets. The airconditioning compressor will run automatically in this setting unless the outside temperature is below 40°F (4.5"C). NORM: This setting bringsin outside air and sends it through the instrument panel outlets. The air conditioning compressor will run automatically in this setting unless the outside temperature is below 40°F (4.5" C). Air Conditioning On very hot days, open the windows long enough to let hot, inside air escape. Thisreduces the time the compressor has to run, which should help fuel economy. For quick cool-down on very hot days, use MAX with the temperature lever all the way to COOL. If this setting is used for long periods of time, the air in your vehicle may become too dry. For normal cooling on hot days, use NORM with the temperature lever all the way to COOL. The system will bring in outside air and cool it. On cool but sunny days, the sun may warm your upper body, but your lower body may not be warm enough. You can use BI-LEV with the temperature knob in the middle. The system will bring in outside air and direct it to your upper body, while sending slightly warmed air to your lower body. You may notice this temperature difference more at some times than others. BI-LEV: This setting bringsin the outside air and directs it two ways. Half of the air is directed through the instrument panel outlets. Most of the remaining air is directed through the floor ducts anda little to the defrost and side window vents. The air conditioning compressor will run automatically in this setting unless the outside temperature is below 40°F (4.5"C). 3-3
