Saturn 2008 Aura Automobile User Manual


 
Use the steps below to place the entire system in
automatic mode:
1. Turn the fan knob and the mode knob to the AUTO
position.
The current set temperature displays. When AUTO
is selected, the air conditioning operation and air
inlet is automatically controlled. The air conditioning
compressor runs while the outside temperature is
over about 40°F (4°C). The air inlet will normally
be set to outside air. If it is hot outside, the air inlet
may automatically switch to recirculate inside air
to help quickly cool down the vehicle.
2. Set the temperature.
An initial setting of 73°F (23°C) is recommended.
Allow about 20 minutes for the system to regulate.
Press the up or down arrow temperature buttons
to adjust the temperature setting as necessary.
If the temperature is set at 60°F (15°C) the system
remains at the maximum cooling setting. If the
temperature is set at 90°F (32°C) the system
remains at the maximum heat setting. Choosing
either maximum setting does not cause the vehicle
to heat or cool any faster.
Be careful not to cover the sensor located on the
top of the instrument panel near the windshield.
This sensor regulates air temperature based on
the intensity of the sun.
Also do not cover the sensor grille on the lower
right side of the climate control faceplate, as
this regulates the inside temperature.
To avoid blowing cold air at engine start-up in cold
weather, the system delays turning on the fan until
warm air is available. The length of delay depends
on the engine coolant temperature. Turning the fan
knob overrides this delay and changes the fan to the
selected speed.
