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 your vehicle until warmer air
is available. The system will start out blowing
air at the floor 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
will depend 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 find 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 will automatically control 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 will be 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 will run automatically.
h (AUTO RECIRCULATION): If the AUTO
position is selected on either the fan or mode
control, the system will automatically control 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.
