Automatic Operation

The system automatically controls the fan speed, air delivery, air conditioning, and recirculation in order to heat or cool the vehicle to the desired temperature.

When the AUTO indicator light is on, the system is in full automatic operation. If the air delivery mode or fan setting is manually adjusted, the auto indicator turns off and displays will show the selected settings.

To place the system in automatic mode do the following:

1. Press AUTO.

2. Set the temperature. Allow the system time to stabilize. Then adjust the temperature as needed for best comfort.

English units can be changed to metric units through the Driver Information Center (DIC). See Vehicle Personalization .
