236 INSTRUMENT PANEL AND CONTROLS located in the overhead console to measure the temperature of the driver and passengers. Based on the sensor input, the system will automatically ocntrol comfort by varying the temperature, fan speed, and mode. This maintains a comfortable temperature, even under changing conditions. It is important that objects are not blocking the infrared sensor. It is also important that objects are not used that may scratch or damage it in any way. Level Of Automatic Control 72°F (22°C) is the recommended setting for maximum comfort for the average person, however, this may vary. NOTE: The temperature setting can be adjusted at any time without affecting automatic control operation. It is not necessary to move the temperature setting for cold or hot vehicles. The system automatically adjusts the temperature, mode and fan speed to provide comfort as quickly as possible. NOTE: In cold weather, the fan will not turn on in AUTO mode until the engine coolant has warmed up sufficiently. This is indicated by the WARM UP DELAY message on the display. NOTE: The temperature can be displayed in U.S. or Metric by selecting the US/M customer programmable feature. Refer to the Overhead Console-Customer Programmable Features. The mode will also be shown in the display and will change as required during automatic operation. NOTE: The system can be put into recirculate mode without affecting ATC operation. This will prevent outside air from entering the vehicle. Use this mode to temporarily block out any outside odors, smoke, or dust.
