Automatic Climate Control System - Pontiac 2005 Bonneville Owner's Manual

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.
1. Press the AUTO button. Whenever this button is
pressed, the display will show the current settings
for five seconds before returning the display to
the exterior temperature.
3-28
2. Adjust the temperature to 75° F (24° C).
Choosing the coldest or warmest temperature
setting will not cause the system to cool or heat any
faster. If you set the system at the coldest or
warmest temperature setting, the system will remain
at the maximum cold or hot setting and fan speed.
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. The
length of time needed for warm up will depend on
the outside temperature and the length of time
that has elapsed since your vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see "Sensors" later in
this section.
