Buick 2004 Automobile User Manual


 
Passenger’s Side Temperature Knob: Turn this knob
clockwise or counterclockwise to manually raise or lower
the temperature on the passenger’s side of the vehicle.
The display will show the temperature setting decreasing
or increasing and the word PASS will appear on the
display. The passenger’s temperature setting can be set
to match and link to the driver’s temperature setting by
pressing and holding the AUTO button for three seconds.
Now, by adjusting the driver’s side temperature setting,
the passenger’s side temperature setting will follow and
both DRIVER and PASS will appear on the display.
The passenger’s side temperature setting also resets
and relinks to the driver’s side temperature setting if the
vehicle has been off for more than two hours.
Automatic Operation
AUTO (Automatic): When automatic operation is
active, the system will control the inside temperature,
the air delivery mode, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the air conditioning
operation and air inlet mode will be automatically
controlled. The air conditioning compressor will run
when the outside temperature is over approximately
40°F (4°C). The air inlet will normally be set to
outside air. If it’s hot outside, the air inlet will
automatically switch to recirculate inside air to
help quickly cool down your vehicle.
2. Set the driver’s and passenger’s temperature.
To find your comfort setting, start with a 72°F (22°C)
temperature setting and allow about 20 minutes
for the system to regulate. Turn the driver’s or
passenger’s side temperature knob to adjust the
temperature setting as necessary. If you choose the
temperature setting of 60°F (15°C), the system
will remain at the maximum cooling setting. If you
choose the temperature setting of 90°F (32°C),
the system will remain at the maximum heat setting.
Choosing either maximum setting may not cause
the vehicle to heat or cool any faster.
