(If Equipped)
Fan Knob
The knob on the le.ft side of the heating system control
panel controls the fan speed. The knob has four speed
positions. To increase airflow, move
the knob toward
HI. To decrease airflow, move it toward LO. To turn the
fan off, move the knob to OFF. If you have the air
conditioner
on, moving the fan knob to OFF also turns
off the A/C compressor.
In
OFF, while driving, ram airflow will vent to the floor
outlets. The mode knob will not redirect ram airflow
to
other selected outlet positions. This is normal operation
for the
OFF position.
Temperature Knob
The middle knob on the control panel lets you select the
relative temperature
of the air flowing into the passenger
area
of your vehicle. This knob will allow you to adjust
the relative air temperature independently of the function
knob setting. Move the
knob clockwise toward the red

Air Conditioning
On hot days, open the windows long enough to let hot
air inside escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
The recirculation button, between the fan and
temperature knobs, allows the air inside your vehicle to
be recirculated. This setting helps to maximize your air
conditioner’s performance and your vehicle’s fuel
economy. This setting also
cools the air the fastest and
can be used to keep unwanted odors and/or dust from
entering the vehicle. When using the air conditioner,
turn off recirculation after the vehicle reaches a
comfortable interior temperature. When the right knob
on the control panel is between
HEATER and
DEFROST, the recirculation feature will not function.
The
A/C button, between the temperature and mode
knobs, allows the air coming into your vehicle to be
cooled. This setting is useful for normal cooling on hot
days. When you use A/C with
the recirculation button
pushed in, turn
off recirculation as soon as the vehicle
reaches
a comfortable interior temperature. With the
A/C on,
move the temperature knob to MAX
for maximum cooling. This setting also puts the system
in the recirculation mode and helps to maximize your
air conditioner’s performance and your vehicle’s fuel
economy. This setting also cools the air the fastest. After
the vehicle’s interior reaches a comfortable temperature,
move the temperature knob clockwise to place the air
conditioning system in the normal mode.
Heating
The heater works best if you keep your windows closed
while using it. On cold days, use the HEATER
or
VENTMEAT setting with the temperature knob in
the red area.
If you use the engine coolant heater before starting your
engine in cold weather,
20°F (-8OC) or lower, your
heating system will produce warmer air faster, to heat
the passenger compartment in cold weather.
The use of an engine coolant heater also reduces the ,
time it takes for the engine to reach normal operating
temperature, and shortens the time it takes the heater to
reach full output. For more information, see “Engine
Coolant Heater” in the Index.
