Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, trunk lamp,
glove box lamp, or the garage door opener. When the
ignition is turned off, the power to these features will
automatically turn off after 10 minutes. Power will
be restored for an additional 10 minutes if any door or
trunk is opened, or the courtesy lamp switch is
turned on.
Battery Run-Down Protection
This vehicle has a feature to help prevent the battery
from being drained, if the interior courtesy lamps,
reading/map lamps, visor vanity lamps or trunk lamp are
accidentally left on. If any of these lamps are left on,
they will automatically turn off after 10 minutes, if
the ignition is off. The lamps will not come back on
again until one of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off, then
on again.
The headlamps will timeout after 10 minutes, if they are
manually turned on before the ignition is off.
Accessory Power Outlet(s)
The accessory power outlets can be used to plug in
electrical equipment such as a cellular telephone,
CB radio, etc.
If your vehicle has a center console, the power outlet is
located inside the lower storage area. There are
outlets also on the right front lower part of the driver’s
seat and under the climate control system next to
the ashtray. SeeCenter Console Storage on page 2-59.
There are two accessory power outlets in the rear
seat area located on the door armrests next to the
ashtrays.
There may be a small cap that must be removed to
access the accessory power outlet. When not using the
outlet be sure to cover it with the protective cap.
The accessory power outlet can be used at any time.
Notice:Leaving electrical equipment plugged in for
an extended period of time while the vehicle is off
will drain the battery. Power is always supplied
to the outlets. Always unplug electrical equipment
when not in use and do not plug in equipment
that exceeds the maximum 20 ampere rating.

Automatic Operation
AUTO9(Automatic Fan):When this position is
selected on the fan control, the system adjusts the fan
speed. If the OnStar
®system is activated when this
position is selected, the climate control fan speed
will lower.
AUTO (Automatic Mode):
1. Turn the fan control to the AUTO position.
2. Turn the mode control to the AUTO position.
3. Adjust the temperature to a comfortable setting
between 68°F (21°C) and 78°F (26°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. In cold weather, the system will start at
reduced fan speeds to avoid blowing cold air into
the vehicle until warmer air is available. The system
starts out blowing air at the oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The
length of time needed to warm the interior depends
on the outside temperature and temperature of
the vehicle.
4. Wait 20 to 30 minutes for the system to stabilize in
order for the system to regulate automatically. Then
adjust the temperature as necessary to nd your
comfort setting.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.
After the vehicle is started, the display will show the
interior temperature settings and the outside
temperature.
If the AUTO position is selected on the fan or mode
control, the system automatically controls the air
conditioning compressor. The A/C compressor will run
automatically even at cool outside temperatures in order
to dehumidify the air. The A/C indicator light is lit
when the system is operating automatically, even at
near freezing outside temperatures. Press the A/C
button on the fan control to turn off the A/C. For
improved window clearing performance in defog or
defrost modes, the A/C compressor runs automatically.
h(AUTO RECIRCULATION):If the AUTO position is
selected on either the fan or mode control, the system
automatically controls the air inlet to supply fresh outside
air or recirculate the interior air to cool the car faster.
The indicator light on the recirculation button will light
whenever the system switches to recirculation. You may
force outside air by pressing the recirculation button when
the light is lit. For vehicles without rear climate controls,
press the outside air button to force outside air. The next
time AUTO fan or mode is selected, the air inlet will reset
back to AUTO operation.

as necessary.
The air conditioning system removes moisture from the
air, so a small amount of water may drip underneath
the vehicle while idling or after turning off the engine.
This is normal.
3-45

In order to prevent false temperature readings at
startup, the displayed temperature will not change
until the following occurs:
Vehicle speed is above 10 mph (16 km/h)
for 5 minutes.
Vehicle speed is above 32 mph (51 km/h)
for 2 and a half minutes.
The climate control system uses the information from
these sensors to maintain your comfort setting by
adjusting the outlet temperature, fan speed, and the
air delivery mode. The system may also supply cooler
air to the side of the vehicle facing the sun. The
recirculation mode will also be used as needed to
maintain cool outlet temperatures.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass.
This can be minimized if the climate control system
is used properly. There are two modes to clear fog
from your windshield. Use the oor/defog mode to
clear the windows of fog or moisture and warm
the passengers. Use the defrost mode to remove
fog or frost from the windshield more quickly.
W(Floor/Defog):Turn the control to this mode to
direct approximately half of the air to the oor outlets
and the remaining air is directed to the side window
outlets and to the windshield. When you select
this mode, the system turns off recirculation and runs
the air conditioning compressor unless the outside
temperature is at or below freezing. The recirculation
mode cannot be selected while in the oor/defog mode.
0(Defrost):Turn the control to this mode to direct
most of the air to the windshield and the side window
outlets. In this mode, the system automatically turns off
recirculation and runs the air conditioning compressor,
unless the outside temperature is at or below freezing.
Recirculation cannot be selected while in the defrost
mode. Do not drive the vehicle until all the windows
are clear.
For professional vehicles, air will be allowed to ow
through the rear outlets. For quicker defrost, press the
AUX button on the front climate control system so
that the light is not lit.
