Automatic Operation AUTO (Automatic): Select AUTO on both the fan speed control and the air delivery mode control knobs to activate the automatic system. When automatic operation is active the system controls the inside temperature and air delivery. To place the system in automatic mode do the following: 1. Turn the fan knob and the mode knob to the AUTO position. The current set temperature displays. When AUTO is selected, the air conditioning operation and air inlet is automatically controlled. The air conditioning compressor runs while the outside temperature is over about 40°F (4°C). The air inlet will normally be set to outside air. If it is hot outside, the air inlet may automatically switch to recirculate inside air to help quickly cool down the vehicle. 2. Set the temperature. An initial setting of 73°F (23°C) is recommended. Allow about 20 minutes for the system to regulate. Press w or x to adjust the temperature setting as necessary. If the temperature is set at 60°F (15°C) the system remains at the maximum cooling setting. If the temperature is set at 90°F (32°C) the system remains at the maximum heat setting. Choosing either maximum setting does not cause the vehicle to heat or cool any faster. Do not to cover the sensor located on the top of the instrument panel near the windshield. This sensor regulates air temperature based on the intensity of the sun. Also do not cover the sensor grille on the lower right side of the climate control faceplate, as this regulates the inside temperature. To avoid blowing cold air at engine start-up in cold weather, the system delays turning on the fan until warm air is available. The length of delay depends on the engine coolant temperature. Turning the fan knob overrides this delay and changes the fan to the selected speed. Manual Operation 9 (Off): Select this position on the fan knob to turn off the entire climate control system. Outside air still enters the vehicle. The airflow direction and temperature can be adjusted. x / w Temperature Control: Press the arrows to increase or decrease the temperature inside the vehicle. 9 (Fan Control): Turn clockwise or counterclockwise to increase or decrease the fan speed. Air Delivery Mode Control: Turn clockwise or counterclockwise to change the direction of the airflow in the vehicle. 4-21
