! Temperature control dial
This dial regulates the temperature of air
flow from the air outlets over a range from
the blue side (cool) to red side (warm). !Fan speed control dial
The fan operates only when the ignition
switch is turned to the “ON ”position. The
fan speed control dial is used to select
four fan speeds. ! Air flow control dial
This dial has the following five positions:
: Air flows through the instrument panel
outlets.
: Air flows through the instrument panel
outlets and the foot outlets.
: Air flows through the instrument panel
outlets, the foot outlets, and some through
the windshield defroster outlets.
: Air flows through the instrument panel
outlets, the windshield defroster outlets,
and the foot outlets.
: Air flows through the instrument panel
outlets and the windshield defroster out- lets. NOTE

perature is low.
For efficient defogging or dehumidify-
ing in cold weather, press the “A/C ”
button.. Even when cooling is not necessary,
setting the temperature much lower
than the current outlet air temperature
turns on the air conditioner compres-

cator light on the control panel illumi-nates.
The automatic climate control system
automatically controls outlet air tempera-
ture, fan speed, air flow distribution air-
inlet control, and air conditioner compres-
sor operation. It activates when the“ AUTO ”button is pressed, and is used to
maintain a constant, comfortable climate
within the passenger compartment.
