Bi-level operation: 1. 2. 3. Move the function selector lever to the PNL/FLR position. Turn on the air conditioning, if desired. Move the temperature control lever to the desired temperature. NOTE: The temperature of the air coming from the panel vents will be cooler than the temperature of the air coming from the floor vents. The difference in temperatures can be controlled by adjusting the temperature control lever. The maximum difference in temperatures will occur when the temperature control lever is in the center range (between the red [warm] and blue [cool] positions). This feature is especially useful on cool yet sunny days, when the vehicle is warmed by the sun yet you desire warmer air at your feet. 4. Set the fan at the desired speed. 122
