Temperature Control

The temperature control performs the following functions:
^ When the system is in the OFF mode, the system turns ON in the AUTO mode when the occupant of the vehicle rotates the temperature control.
^ When the system is in any mode except OFF, the temperature control performs one of the following actions:
- If the temperature is 19°-29°C (66°C-84°F), rotating the temperature control increases/decreases the internal temperature setting by per detent.
- If the temperature is 18°C (65°F), adjusting to the next lower detent decreases the internal temperature setting to 16°C (60°F) which is the setting for MAX cooling.
- If the temperature is 30°C (85°F), adjusting to the next higher detent increases the internal temperature setting to 32°C (90°F) which is the setting for MAX heating.

A change in the temperature setting causes the Instrument Panel Module (IPM) to bring the passenger compartment temperature to the new setting. This is done by changing any of the following:
^ The blower speed
^ The air delivery mode
^ The air discharge temperature
^ The air intake position
