Automatic Operation
AUTO (Automatic): Select AUTO on both the fan
speed knob and the air delivery mode knob to
activate the automatic system. When automatic
operation is active the system controls the
inside temperature and air delivery.
Use the steps below to place the entire system in
full automatic control:
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 is normally
set to outside air. If it is hot outside, the air
inlet can 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
w or x 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.
