Temperature Button

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 presses temperature UP or DOWN button.
^ When the system is in any mode except OFF, either button performs one of the following actions:
- If the temperature is 19°-29°C (66°-84°F), pressing WARM/COOL buttons increases/decreases the set temperature by 1 degree.
- If the temperature is 18°C (65°F), pressing the COOL button decreases the set temperature to 16°C (60°F) which is the setting for MAX cooling.
- If the temperature is 30°C (85°F), pressing the WARM button increases the set temperature to 32°C (90°F) which is the setting for MAX heating.

A change in the temperature setting signals the Instrument Panel Module (IPM) to bring the passenger compartment temperature to the new setting. To do this the system may change one or more of the following:
^ The air discharge temperatures
^ The blower speed
^ The air delivery mode
