Saturn 2007 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 your 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.
Manual Operation
You can also manually adjust the air delivery
mode or fan speed.
9(Off): Select this position on the fan knob to
turn off the entire climate control system.
Outside air still enters the vehicle, and is directed
to the floor. The direction can be changed by
changing the mode position. The temperature can
also be adjusted using either the up or down
arrow temperature buttons.
9(Fan): Turn the knob with the fan symbol to
manually adjust the fan speed.
