The ATC system uses an infrared sensor located in the
overhead console to measure the temperature of the
driver. Based on the sensor input, the system will auto-
matically control comfort by varying the temperature, fan
speed, and mode. This maintains a comfortable tempera-
ture, even under changing conditions. It is important that
the infrared sensor is kept clean and that objects are not
blocking the 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 tem-
perature, 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 ЉOverhead Console-Customer Pro-
grammable Features.Љ 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 out-
side air from entering the vehicle. Use this mode to
temporarily block out any outside odors, smoke, or dust.
