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 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.
