Operating the RECIRC mode in cold temperatures or under high humidity conditions may cause moisture to form on the inside of the windshield. If this condition occurs, deselect the RECIRC button. Air Conditioning The air conditioner cools, dehumidifies and filters the air for the inside of the vehicle. The air conditioning compressor is enabled in all modes unless the A/C ON button is in the off position (indicator light will not be illuminated). However, the air conditioning compressor will not operate when the outside temperature is below 44°F (7 "C). When the air conditioner is on, you may sometimes notice slight changes in your vehicle's engine speed and power. This is normal, because the system is designed to cycle the compressor on and off to keep the desired cooling and help fuel economy. On very hot days, open the windows long enough to let the hot air out. This reduces the time required to cool the interior of the vehicle to a comfortable level.If the system is in the automatic mode (AUTO-PUSH knob indicator light is on), during very hot days the system will automatically go to the RECIRC mode and the temperature door will be positioned at the full cold position for maximum cooling. You can choose the extreme comfort setting of 60°F ( 16"C), but the system will not cool any faster by choosing the extreme comfort setting. A/C ON: Press this button to turn the air conditioning on and off. If the system is operating in the automatic mode, the A/C ON indicator light will automatically illuminate. In the auto mode, the A/C compressor will only operate when the system determines it is needed. OFF: Rotate the AUTO-PUSH knob to the OFF position. Turning the system off will cause the fan to turn off and the airflow to be directed out the lower floor outlets. The system will still try to keep the interior of the vehicle at the previously chosen comfort setting. The outside temperature will show in the display when the system is OFF.
