2006 Chevrolet Silverado 1500 Pickup Owner's Manual - Page 202

Whenever you press AUTO, the display will change to show the following: • The current driver's set temperature and an arrow for five seconds • The current passenger's set temperature setting and an arrow for five seconds If the air conditioning is on and the outside temperature drops below a temperature which is too cool for air conditioning to be effective, the snowflake symbol will turn off to let you know the air conditioning mode has been canceled. When air conditioning is selected or in AUTO mode, the system will run the air conditioning automatically to cool and dehumidify the air entering the vehicle. If you select A/C off while in front defrost, defog or recirculation, the A/C snowflake symbol will turn off, but the A/C compressor will still run to help prevent fogging. On hot days, open the windows long enough to let hot inside air escape. This reduces the time it takes for your vehicle to cool down. Then keep your windows closed for the air conditioner to work its best. On cool, but sunny days while using manual operation of the automatic system, use bi-level to deliver warm air to the floor and cooler air to the instrument panel outlets. To warm or cool the air delivered, turn the temperature knob to the desired setting. In AUTO mode the system will cool and dehumidify the air inside the vehicle. Also while in AUTO mode, the system will maximize its performance by using recirculation as necessary. • The automatic air delivery mode and fan speed If the driver's and passenger's temperature settings are the same when AUTO is pressed, the temperature setting and both arrows will be displayed for five seconds along with the automatic air delivery mode and fan speed. After the five second update, the display will change to show the temperature setting, both arrows and AUTO. Air Conditioning #(Air Conditioning): Press this button to turn the air conditioning (A/C) compressor on and off. The snowflake symbol will appear on the display when the A/C is on and will turn off when the air conditioning is off. Pressing this button when the outside temperature is too cool for air conditioning will make the snowflake symbol flash three times and then turn off to let you know the air conditioning mode is not available. 3-28
