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 the 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.
Do not 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.
