Heating and Cooling

Proper use of the Heating and
Cooling system can make the

interior dry and comfortable, and

keep the windows clear for best

visibility.

What Each Control Does
Fan Control Lever
Sliding this lever to the right
increases the fan's speed, which
increases air flow.
Temperature Control Lever
Sliding this lever to the right
increases the temperature of the air

flow.

Air Conditioning (A/C) Button
This button turns the air condi- tioning ON and OFF. The indicator
in the button lights when the A/C is
on.
Rear Window Defogger Button
This button turns the rear window defogger on and off (see page 63). Recirculation Button
This button controls the source of the air going into the system. When
the indicator in this button is lit, air
from the vehicle's interior is sentthrough the system again (Recircula-
tion mode). When the indicator is off,air is brought in from outside the
vehicle (Fresh Air mode).

Heating and Cooling

Vent Controls
You can adjust the direction of the
air coming from the dashboard vents

by moving the tab in the center of
each vent up-and-down and side-to-

side.
The vents in the corners of the

dashboard can be opened and closed

with the dials underneath them. 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.

Heating and Cooling

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

clears.

The outside air intakes for the heating and cooling system are at
the base of the windshield. Keep
these clear of leaves and other
debris.
Ventilation

The flow-through ventilation system
draws in outside air, circulates it
through the interior, then exhausts it
through vents near the rear window. 1. Slide the temperature control lever
all the way to the left.
Make sure the A/C is off. 2. Select and Fresh Air mode.
3. Set the fan to the desired speed.

Heating and Cooling

If the interior is very warm from
being parked in the sun, you can cool it down more rapidly by setting up
the controls this way:
1. Start the engine.
2. Turn on the A/C by pressing the button. Make sure the tempera-
ture control lever is all the way to
the left.
3. Set the fan to maximum speed.
4. Open the windows partially. Select and Fresh Air mode.
When the interior has cooled down to a more comfortable temperature,close the windows and set the
controls as described for normal
cooling. Air conditioning places an extra load
on the engine. Watch the engine
coolant temperature gauge (see page 57) when driving in stop-and-go
traffic or climbing a long, steep hill. If it moves near the red zone, turnoff the A/C until the gauge reads
normally.

To Heat

To warm the interior: 1. Start the engine. 2. Select and Fresh Air mode.
3. Set the fan to the desired speed.
4. Adjust the warmth of the air with
the temperature control lever.
To Heat and Dehumidify with Air

Conditioning

Air conditioning, as it cools, removes moisture from the air. When used in
combination with the heater, itmakes the interior warm and dry.
1. Switch the fan on.
2. Turn on the air conditioning. 3. Select and Fresh Air mode.
4. Adjust the temperature control
lever so the mixture of heated and
cooled air feels comfortable.
This setting is suitable for all driving conditions whenever the outside
temperature is above 32°F (0°C).

Fuel Economy

The condition of your vehicle and your driving habits are the two most important things that affect the fuel
mileage you get.
Vehicle Condition Always maintain your vehicle accord- ing to the maintenance schedule.
This will keep it in top operating condition.
An important part of that mainte- nance is the Owner MaintenanceChecks (see page 171). For
example, an underinflated tire
causes more "rolling resistance,"
which uses fuel. It also wears out
faster, so check the tire pressure at
least monthly.
In winter, the build-up of snow on
your vehicle's underside adds weight and rolling resistance. Frequent
cleaning helps your fuel mileage and
reduces the chance of corrosion. Driving Habits
You can improve fuel economy by driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more fuel.
Always drive in the highest gear that allows the engine to run and acceler-
ate smoothly.
Depending on traffic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your vehicle uses extra fuel. Use the cruise control, when appropriate, to
increase fuel economy. A cold engine uses more fuel than a
warm engine. It is not necessary to "warm-up" a cold engine by letting it
idle for a long time. You can drive
away in about a minute, no matter
how cold it is outside. The engine
will warm up faster, and you get better fuel economy. To cut down on
the number of "cold starts," try tocombine several short trips into one.
The air conditioning puts an extra load on the engine which makes ituse more fuel. Turn off the A/C to
cut down on air conditioning use.
Use the flow-through ventilation
when the outside air temperature ismoderate.
