2004 BUICK REGAL climate control

Dual Automatic Climate Control
System
The vehicle may have this climate control system. The
heating, cooling and ventilation can be controlled
with it.
Automatic Operation
AUTO (Automatic):Press the AUTO button for
automatic control of the inside temperature, the air
delivery mode and the fan speed. There might be 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.
3-20

2. Press the AUTO button.
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster.
If the system is set at the warmest temperature
setting, 90°F (32°C), hot air will be directed to the
oor, 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 the system is set at the coldest temperature
setting, 60°F (15°C), 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 the vehicle
until warmer air is available. The system will
start 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 for warm up will depend on
the outside temperature and the length of time
that has elapsed since the 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
“Solar Sensor” later in this section.
Manual Operation
During daylight hours, the instrument panel brightness
control might need to be adjusted to the highest setting,
in order to see the indicator lights for the various
climate control settings.
OFF:Pressing the OFF button cancels automatic
operation and places the system in manual mode. Press
the AUTO button to return to automatic operation.
TEMP (Temperature):To manually adjust the
temperature inside the vehicle, press the up arrow on
the TEMP control to raise the temperature and press the
down arrow to lower the temperature. The display will
show the selection for a few seconds, and then the
outside temperature will be displayed.
When the DUAL light indicator is on, this means the
TEMP control has set the temperature for the driver.
When the DUAL light indicator light is not on, this means
the TEMP control has set the temperature for the
entire cabin.

For quick cool down on hot days, press the AUTO
button. The system will automatically enter the
recirculation mode where the temperature will be at the
full cold position for maximum cooling.
The air-conditioning system removes moisture from the
air, so a small amount of water dripping underneath
the vehicle while it is idling or after the engine is turned
off is normal.
Operating the climate control system in the RECIRC
mode may cause fogging of the vehicle’s windows when
the weather is cold and damp. To clear the fog, select
either WINDSHIELD/FLOOR or defrost mode and
increase the speed.
Sensors
The solar sensor on the vehicle monitors the solar heat
and the air inside of the vehicle. This information is
used to maintain the selected temperature by regulating
adjustments to the temperature, the fan speed, and
the air delivery system. The system may also supply
cooler air to the side of the vehicle facing the sun. The
recirculation mode will also be activated, as necessary.
Do not cover the solar sensor located in the center
of the instrument panel, near the windshield, or
the system will not work properly.
Passenger Control
The arrow buttons to control the temperature on the
passenger side of the vehicle are located to the right of
the PASSENGER CONTROL window. Press the
DUAL button so that the indicator light is on. Press the
right arrow to raise the temperature and press the
left arrow to lower the temperature on the passenger
side of the vehicle.
If the indicator light below the arrows is amber this
indicates that the passenger side temperature is
set the same as the driver’s side.
If the indicator light below the arrows is red, this
indicates that the passenger side temperature is
set warmer than that of the driver’s side.
If the indicator light below the arrows is blue this
indicates that the passenger side temperature is
set cooler than that of the driver’s side.
Defogging and Defrosting
Fog on the outside of the windows is a result of high
humidity causing moisture to form and condense on the
cool window glass. This can be minimized if the climate
control system is used properly. There are two modes to
clear fog or frost from the windshield and side windows.

Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specied government test course.
For example, a tire graded 150 would wear one and
a half (1.5) times as well on the government course as
a tire graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart signicantly from the norm
due to variations in driving habits, service practices and
differences in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire’s ability
to stop on wet pavement as measured under controlled
conditions on specied government test surfaces of
asphalt and concrete. A tire marked C may have poor
traction performance. Warning: The traction grade
assigned to this tire is based on straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.
Temperature – A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation
of heat and its ability to dissipate heat when tested
under controlled conditions on a specied indoor
laboratory test wheel. Sustained high temperature can
cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a
level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inated and not
overloaded. Excessive speed, underination, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
