How to Use the System

This section covers how to set up the system controls for ventilation,
heating, cooling, dehumidifying, and defrosting.
The engine must be running for the heater and air conditioning to
generate hot and cold air. The heater
uses engine coolant to warm the air.If the engine is cold, it will be several
minutes before you feel warm air
coming from the system.
The air conditioning does not rely on engine temperature.
It is best to leave the system in Fresh
Air mode under almost all conditions. Keeping the system in Recirculation
mode, particularly with the A/C off,can cause the windows to fog up.
Switch to Recirculation mode when
you are driving through smoky or dusty conditions, then switch back to
Fresh Air mode when the condition

through the interior, then exhausts it
through vents near the rear side

panels.

1. Turn the temperature control dial all the way to the left.

Heating and Cooling

These settings direct all the air flow to the defroster vents at the base ofthe windshield and the side windowdefroster vents. The air flow will get
warmer and clear the windows faster as the engine warms up. You can
close the corner vents with the dial
beside each vent. This will send
more warm air to the windshield
defroster vents.
For safety, make sure you have a
clear view through all the windows
before driving away. To Turn Everything Off

turn the fan speed and temperaturecontrol dials all the way to the left.
You should shut the system completely off only for the first few
minutes of driving in cold weather,
