Automatic Operation
AUTO 9 (Automatic Fan): When this position is
selected on the fan control, the system adjusts the fan
speed.
To use automatic operation:
1. Turn the fan control to the AUTO position.
2. Turn the air delivery mode to the AUTO position.
3. Adjust the temperature to a comfortable setting
between 21°C (68°F) and 26°C (78°F).
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 the vehicle until warmer air is available. The
system starts 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 depends
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 shows the
interior temperature settings and the outside
temperature.
