Air Conditioning Operation
To turn on the Air Conditioning, set the fan control at any
speed and press the snowflake button located at the right
of the control panel. Conditioned air will be directed
through the outlets selected by the mode control. A light
in the snowflake button shows that the air conditioning is
on. Press the button a second time to turn the air
conditioning off.
Slight changes in engine speed or power may be noticed
when the air conditioning compressor is on. This is anormal occurrence as the compressor will cycle on and
off to maintain comfort and increase fuel economy.
The mode control (at the right of the
control panel) can be set in any of the
following positions:
NOTE:To improve your selection choices, the system
allows you to operate at intermediate positions between
the major modes. These intermediate positions are iden-
tified by the small dots.
Recirculation Modes (Panel or Bi-Level )
Select the recirculation modes when
the outside air contains smoke, odors,
high humidity, or if rapid cooling is
desired. This feature allows for recir-
culation of interior air only. Air flows
through the panel outlets in this mode.

Circulation
The cab is designed with features to promote outside air
circulation. There are grilles in the cab back panel. These
are air exhausters that provide the means for regular
exchange of cab air.
Side window demisters direct air flow specifically to the
window glass to help prevent interior fogging of the
glass. They are located in the extreme outside upper
edges of the instrument panel. The demisters also pro-
vide extra air ducts for circulation. They are in operation
whenever the Floor, Mix or Defrost modes are in use.
NOTE:When you turn off the engine you may hear a
hissing sound from under the hood for a short period of
time. This is a normal condition that occurs if the air
conditioning system has been on. It is not an indication of
a problem with the air conditioning system.
Operating Tips
Fast Cooldown
For a fast cooldown, turn the blower fan rotary knob to
the extreme right position, turn the mode control to the
panel fresh position, press the snowflake button to turnon the air conditioning, and drive with the windows
open for the first few minutes. Once the hot air has been
expelled, close the windows and turn the mode selector
to the Recirculation Panel Mode or Recirculation Mode
Bi-level position. When a comfortable condition has been
reached, choose a mode position and adjust the tempera-
ture control knob and blower speed as necessary to
maintain comfort. For high humidity conditions it may
be necessary to remain in the Recirculation mode to
maintain comfort.
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it's rainy or humid. In most cases
turning on the Air-conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction and blower speed to maintain comfort.
As the temperature gets colder it may be necessary to
direct air onto the windshield by using MIX Mode
position on the control. Adjust the temperature control
and blower speed to maintain comfort. High blower

speeds will reduce fogging. Interior fogging on the
windshield can be quickly removed by selecting the
defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended.When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear.
When stopped in heavy traffic, it may be necessary to
shift into NEUTRAL and depress the accelerator slightly
for fast idle operation.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.

STARTING PROCEDURES
The starter should not be operated for more than 15
second intervals. Waiting a few seconds between such
intervals will protect the starter from overheating.
Manual Transmission
Apply the parking brake, place the gearshift control lever
in NEUTRAL and depress clutch pedal to the floor before
starting the vehicle. This vehicle is equipped with a
clutch interlocking ignition system. It will not start unless
the clutch is depressed.
Automatic Transmission
Start the engine with the shift lever in NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle. If the vehicle has a discharged battery,
booster cables may be used to obtain a start from a
booster battery or the battery in another vehicle. This
type of start can be dangerous if done improperly.
See section 6 of this manual for the proper jump
starting procedures and follow them carefully.
Normal Starting
Normal starting of either a warm or cold engine is
obtained without pumping or depressing the accelerator
pedal. Turn the key to the START position and release
when the engine starts. If the engine fails to start within
10 seconds, turn the key to the OFF position, wait 5
seconds, then repeat the starting procedure.
144 STARTING AND OPERATING

If Engine Fails To Start
If the engine fails to start after you have followed the
Normal Starting procedure, it may be flooded. Push the
accelerator pedal all the way to the floor and hold it there
while cranking the engine. This should clear any excess
fuel in case the engine is flooded.
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the key is
released. If this occurs, continue cranking with the accel-
erator pedal pushed all the way to the floor. Release the
accelerator pedal and the key once the engine is running
smoothly.If the engine shows no sign of starting after two 15
second periods of cranking with the accelerator pedal
held to the floor, the Normal Starting procedure should
be repeated.
WARNING!
Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
After Starting
The idle speed is automatically controlled on fuel injected
engines and will decrease as the engine warms up.

CAUTION!
Long periods of engine idling can cause excessive
exhaust temperatures which can damage your ve-
hicle. Do not leave your vehicle unattended with the
engine running.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
Engine Block Heater Ð If Equipped
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 volt AC electrical outlet with a
grounded, three wire extension cord.
The engine block heater cord is located at the right front
of the engine compartment for all engine applications.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt electrical cord could
cause electrocution.
SHIFTING
Automatic Transmission
The gear shift lever is mounted on the right side of the
steering column. To engage a gear for driving, move the
shift lever from P-Park or N-Neutral to the desired gear
range (R-Reverse, D-Drive, 2±Second, or 1±First). To
move the shift lever, pull it toward you, then release it
when the desired gear range is reached. The Transmis-
sion Range Indicator (labeled ªGear Selectorº) in the
instrument cluster shows the selected gear range. The
Indicator is illuminated for night driving.
Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of Park and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
146 STARTING AND OPERATING

switch is in the ON position. Always depress thebrake
pedal first,before moving the gear selector out of PARK.
Gear Ranges
DO NOT race the engine when shifting from Park or
Neutral position into another gear range.
ªPº Park
This position supplements parking brake by locking the
transmission. The engine can be started in this range.
Never use Park while the vehicle is in motion. Apply the
parking brake when leaving vehicle in this range. Always
apply the parking brake first, then place the selector in
the Park position.
WARNING!
Your vehicle could move and injure you and others if
it is not completely in P (Park). Check by trying to
move the gearshift lever back and forth without first
pulling the lever toward you, after you have set it in
P. Make sure it is in Park before leaving the vehicle.
WARNING!
Never use Park position on an automatic transmis-
sion as a substitute for the parking brake. Always
apply parking brake fully when parked to guard
against vehicle movement and possible injury or
damage.
WARNING!
It is dangerous to shift the selector lever out of ªPº or
ªNº if the engine speed is higher than idle speed. If
your foot is not firmly on the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and when your right
foot is firmly on the brake pedal.
ªRº Reverse
Use this range only after the vehicle has come to a
complete stop.
