Dual Automatic Climate Control System - Buick 2003 Century Owner's Manual

Dual Automatic Climate Control
System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic): Press the AUTO button for
automatic control of the inside temperature, the air
delivery mode and the fan speed. You may notice a
delay of two to three minutes before the fan comes
on when the automatic operation is used in cold
weather.
For the automatic system to function, the temperature
must be set between 61°F (16°C) and 89°F (31 "C).
1. Adjust the temperature to a comfortable setting.
2. Press the AUTO button.
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster.
If you set the system at the warmest temperature
setting, 90°F (32"C), hot air will be directed to the
floor, the fan will increase to the highest speed, and,
the system will remain in manual mode at that
temperature. The system will not return to automatic
until the temperature setting is lowered.
If you set the system at the coldest temperature
setting, 60°F (ISOC), cold interior air will be
recirculated through the air panel outlets, and the
fan will increase to the highest speed. The
system will not return to automatic until the
temperature is raised.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the floor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting.
