~ . le Knob - Automatic
Operation
I he right knob on the control panel allows you to
choose the direction of air delivery. When the system is
set
for automatic operation, sensors will control the air
delivery mode. Air will come primarily from the floor
or
instrument panel outlets, with some air directed to the
windshield to prevent fogging.
When the system is
in AUTO mode, the air conditioning
light will turn on, and
the recirculation and outside air
lights
turn off. With the system in full auto control
(both the fan and mode knobs
in AUTO), YOLI still
have the ability to override any function. However?
continually overriding the outside air or the A/C
compressor will
limit the ability of the system to cool
the vehicle quickly.
If you push a button for a function which is not
available, the light next to that button
will flash three
times to alert you that it's
not available.
To find your comfort zone, start with the
74°F (23°C)
setting and allow about 20 minutes for the system to
adjust the temperature
if necessary.
With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air.
In cold weather, when the system senses the need
for heat, the airflow will be directed out the floor outlets.
As the
interior temperature approaches a desired
setting,
the blower speed will decrease. To maintain
interior comfort, the airflow will adjust between the
instrument panel air outlets and
floor outlets. On bright
sunny days in cool weather, the airflow may come out
of
the air conditioning and floor outlets (bi-level mode) to
maintain comfort and prevent stuffiness.
To avoid blowing cold air
in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started.
As the coolant
warms
up, the blower fan speed will gradually increase
and air will flow from the heater outlets, with some
airflow to the windshield to prevent fogging under most
normal conditions.
If your vehicle is sitting out on a warm day and you
have the filn set on AUTO, the air
will first flow out of
the floor air outlets for
a few seconds. That is normal.
This is to expel hot air from the air outlets.
As the air is
cooled, the airflow
will move through the air
conditioning outlets.
Be careful
not to put anything over the solar sensor
located around the center of the instrument panel.
This sensor is used by the automatic system
to
regulate temperature.

Mode Knob - Manual Operation
The right knob on the control panel allows you to
choose the direction of air delivery.
You can choose to set the climate control system
operations yourself, or let the system work for
you
by placing the system in AUTO mode. See “Mode
Knob
- Automatic Operation” earlier in this section.
/.I PANEL: This setting directs most of the air
through the instrument panel outlets and a small amount
through the
floor outlets.
’# BI-LEVEL: Air is delivered through the heater
floor outlets
as well as the instrument panel outlets.
+’ HEATER: This setting directs most of the
warmed air through the heater floor outlets and some air
through the windshield defroster outlets.
+e
+e
e
‘/.I BLEND: Airflow is divided equally between the
heater floor outlet and the windshield defroster outlets.
The air conditioning compressor may
run to dehumidify
the air to prevent window fogging.
DEFROST This setting directs most air through
the windshield defroster outlets and some through the
heater outlets. The air conditioning compressor may
run
to dehumidify the air to prevent window fogging.
a OUTSIDE AIR: Press this button to force the
system to use outside air. Press
it again to close off the
outside air.
Pressing the OUTSIDE AIR button
will cancel the
RECIRCULATION button.
RECIRCULATION: Press this button to limit
the amount of fresh air entering your vehicle. This is
helpful when you are trying to
limit odors e.ntering your
vehicle.
In the AUTO mode, the system will use
recirculation as necessary to cool the air. Pressing the
recirculation button
will change the operation to a
manual mode and the air
will recirculate non-stop. Press
this button again to turn off the recirculation feature.
RECIRCULATION may be selected
with the fan control
in OFF to limit odors, outside air and dust from entering
your vehicle.
Pressing the RECIRCULATION button will cancel the
OUTSIDE AIR button.
0 A/C: Press this button to turn the air conditioning
on and off. The system will cool and dehumidify the air
inside the vehicle.
Air conditioning
will be automatically disabled when
the outside temperature drops below
a level which air
conditioning is ineffective.

Remember that in order for the automatic system
to perform
well, it needs A/C to provide
cooling performance.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air 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.
For quick cool-down on very hot days, use
MAX A/C
with the temperature knob turned to the left. This setting
should be used to keep odors and/or dust from entering
the vehicle. For normal cooling on hot days, use A/C
with the temperature knob turned to the left.
On cool but sunny days, use BI-LEVEL A/C to deliver
warm air to the floor and cooler air to the instrument
panel outlets.
When the air conditioner is on, you may sometimes notice
slight changes
in your vehicle‘s engine speed and power.
This
is normal because the system is designed to cycle the
compressor on and off to keep the desired temperature.
Heating
The heater works best if you keep your windows closed
while using
it. On cold days, use HEATER with the
temperature knob turned
to the right. BLEND is useful
in cool weather when you have fog or ice on the
windshield or side windows.
If you use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer air faster to heat the passenger compartment in
cold weather. See “Engine Coolant Heater”
in the Index.
Ventilation System
For mild outside temperatures when little heating or
cooling
is needed, use VENT to direct outside air
through your vehicle. Airflow is through the instrument
panel outlets.
Your vehicle’s ventilation system supplies outside air to
the inside of your vehicle when
it is moving. When the
vehicle is
not moving, you can get outside air to flow
through by selecting any mode and any fan speed.

Part C: Periodic Maintenance
Inspections
Listed below are inspections and services which should
be performed at least twice a year (for instance, each
spring and fall). You should
let your retailer’s service
department or other qualified service center do these
jobs. Make sure any necessary repairs are completed
at once.
Proper procedures to perform these services may be
found in a service manual. See “Service and Owner
Publications” in the Index.
Steering, Suspension and Front Drive Axle
Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or
lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Clean and then inspect the drive
axle boot seals for damage, tears
or leakage. Replace
seals
if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near the exhaust system.
Look for broken, damaged,
missing or out-of-position parts
as well as open seams,
holes, loose connections or other conditions which could
cause
a heat build-up in the floor pan or could let
exhaust fumes into the vehicle. See “Engine Exhaust”
in
the Index.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace
as needed. Clean the outside
of the radiator and air conditioning condenser.
To help
ensure proper operation, a pressure test of the cooling
system and pressure cap is recommended at least once
a year.
