The ATC system uses infrared (I/R) sensors to monitor and control occupant comfort levels. This sensing system replaces interior air temperature and solar sensors which required complex control programs to maintain occupant comfort levels. The front I/R sensor is located in the instrument panel center bezel outlet. The rear I/R sensor is located in the rear overhead mounted ATC switch.
