Temperature Control: Select the desired cabin air
temperature between 60-90°F (16-32°C). Typically, the
best setting is near 75°F (23°C). Choosing the
coldest or warmest temperature setting does not cause
the system to heat or cool any faster. In cold weather;
the system starts at lower fan speeds to avoid blowing
air into the vehicle until warmer air is available. The
system begins blowing air at the floor, but can change
modes automatically as the vehicle warms up to
maintain the chosen temperature setting.
Do not to cover the sensor located on the top of the
instrument panel near the windshield.
AUTO (Automatic Air Delivery Mode): Turn the air
delivery mode knob to AUTO for the system to
automatically control the direction of the airflow to help
reach the desired inside temperature.
The system automatically controls the air inlet to supply
the outside air or recirculated inside air needed to
heat or cool the vehicle faster. The indicator light on the
recirculation button will be lit whenever the system
switches to recirculation.

You can switch to outside air by pressing the outside air
button. However, the recirculation mode may turn
back on automatically.
In cold weather, the system starts at lower fan speeds
to avoid directing cold air into the vehicle until warmer air
is available. The climate control system directs air to
the floor, but may automatically change modes 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
inside temperature of the vehicle.
@
(Automatic Recirculation): Using the previous
temperature setting, the system automatically controls
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 lights whenever the system
switches to recirculation. Switch to outside air by
pressing the outside air button. The next time AUTO fan
or AUTO mode is selected, the air inlet resets back to
auto operation.
