Temperature Button

When the system is in the OFF mode, pressing either end of the temperature rocker switch causes the system to turn on in the AUTO mode.

In any mode except OFF, pressing the temperature rocker switch performs one of the following actions:
^ If the temperature is 19°-2g°C (66°-84°F), pressing the increase/decrease end of the rocker switch once increases/decreases the internal temperature setting by 1 degree.
^ If the temperature is 18°C (65°F), pressing the decrease end of the rocker switch once decreases the internal temperature setting to 16°C (60°F).
^ If the temperature is 30°C (85°F), pressing the increase end of the rocker switch once increases the internal temperature setting to 32°C (90°F).

A change is the temperature setting signals the heater and A/C programmer to bring the passenger compartment temperature to the new setting. This is done by changing:
^ The blower speed
^ The air discharge location
^ The air discharge temperature
