Flow-Through Ventilation System
Your vehicle's flow-through ventilation system supplies outside a\
ir to the
inside of your vehicle when it is moving. With the side windows closed, air
will flow into the front air inlet grilles, through the vehicle, and out the rear
air exhaust valve. Outside air will also enter the vehicle whe\
n the heater
or
the air conditioning fan is running.
Ventilation Tips
Keep the hood and front air inlet free of ice, snow, or any other
obstruction (such as leaves). The heater and defroster will w\
ork far
better, reducing the chance
of fogging the inside of your windows.
When you enter a vehicle in cold weather, turn the blower fan to HI for
a few moments before driving off. This helps clear the intake ducts of
snow and moisture, and reduces the chance of fogging the insid\
e of
your windows.
Keep the air path under the front seats clear of objects. This helps air to
circulate throughout your vehicle.

Downloaded from www.Manualslib.com manuals search engine Air Vents
You will find air vents in the center and on the sides of your instrument
panel. You can move the vents to direct the flow
of air, or close the vents
altogether. When you close a vent,
it will increase the flow of air coming out
of any vents that are open.
Heater Controls
If your vehicle does
not have
air
conditioning, your
heater controls will
look like this.
The switch on the righthand side changes the fan speed. To increase the
fan
speed, push the switch upward toward HI. To decrease the fan speed, push
the switch downward toward
LO .
The upper knob changes the air temperature. Turn the knob right (clockwise)
for warmer
air. Turn the knob left (counterclockwise) for cooler air.
The lower knob changes the heater function and determines which\
outlets
the
air will flow through (instrument panel, defroster, heater, etc.).

Downloaded from www.Manualslib.com manuals search engine OFF: This setting turns off all heating functions. Some outside air will still
come out of the heater outlet whenever the vehicle is moving forward.
VENT Airflow is through the instrument panel vents. Set the upper knob to
the temperature desired. This setting is useful for mild outside temperatures,
when little heating
or cooling is desired.
BI-LEV: Outside air comes in through the heater floor vents and the
instrument panel vents. This setting is useful in cool weather \
with bright sunlight.
HEAT Heated air comes out through the heater floor vents and windsh\
ield
defroster vents. This setting is useful for cold weather.
BLEND: Airflow is divided equally between the heater floor vent and t\
he
windshield defroster vents. This setting is useful in cool weather when you
have fog or ice on the windshield or side windows.
DEF: This setting directs most air through the windshield defroster \
vents
and some through the heater vents. This setting is useful when\
you have fog
or ice on the windshield.
Heater/Air Conditioning Controls
If your vehicle has air
conditioning, your
heatedair conditioning
controls will look like
this.
Before using your vehicle's air conditioning, open the windows \
to clear the vehicle
of hot air.
The switch on the righthand side changes the fan speed. To increase the fan
speed, push the switch upward toward
HI. To decrease the fan speed, push
the switch downward toward
LO .
The upper knob changes the air temperature. Turn the knob righ\
t (clockwise)
for warmer air. Turn the knob left (counterclockwise) for coo\
ler air.
The lower knob changes the heater function and determines which out\
lets
the air will flow through (instrument panel, defroster, heater, etc\
.).

Fluid Leak Check
After the vehicle has been parked for a while, inspect the su\
rface under the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning system after it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.

Air Conditioning Refrigerants
Not all air conditioning refrigerants are the same. If the air conditioning
system
in your vehicle needs refrigerant, be sure the proper refrigerant is
used. If you’re not sure, ask your
GM dealer. For additional information, see
your “Warranty and Owner Assistance Information” booklet.

R-l34a c-60 30 oz. (35 kg)
*All

NOTICE:
R-134a refrigerant is not compatible with R-12 refrigerant in
an air conditioning system. R-12 in an R-134a system will caus\
e
compressor failure, refrigerant oil sludge,
or poor air
conditioning system performance.

Downloaded from www.Manualslib.com manuals search engine Explanation Of Scheduled Maintenance Services
Below are explanations of the services listed in the maintenance charts.
The proper fluids and lubricants to use are listed
in this section. Make sure
whoever services your vehicle uses these. All parts should be \
replaced and
all necessary repairs done before you or anyone else drives the vehicle.
1. ENGINE OIL AND OIL FILTER CHANGE* - ALWAYS USE
API SERVICE SH OR SG ENERGY CONSERVING I1 OILS
OF THE
PROPER VISCOSITY. The “SH” or
“SG’ designation may be shown
alone or in combination with others, such as “SWCD”, or
“SH, SG,
CD,” or “SGKD”, etc. To determine the preferred viscosity oil for your
vehicle’s engine (e.g. SAE 5W-30), see “Engine
Oil” in the Index.
2. CHASSIS LUBRICATION - Lubricate the front suspension, ball
joint, steering linkage, and transfer case shift linkage, parking brake\

cable guides, propshaft splines, universal joints, brake pedal springs,
and clutch pedal springs at the intervals specified on the proper
maintenance schedule, or at every engine oil change, whichever comes
first
.
Ball joints should not be lubricated unless their temperature is 10°F
(-12°C) or higher. When the weather is cold, let them warm up before
lubricating them or they could be damaged.
Also, be sure
to check all the vehicle fluid levels at this time.
3.
COOLING SYSTEM SERVICE* - Drain, flush and refill the
system with new or approved recycled coolant conforming to “\
GM
Specification 6038-M” (4.3L engine) or “GM Specification 6043-M”
(2.2L engine). See “Engine Coolant” in the Index for the proper coolant
and mixture to use in your vehicle.
Also inspect the hoses and replace them if they are cracked, \
swollen, or
deteriorated. Clean the outside of the radiator and air conditioning
condenser. Wash the radiator neck. To ensure proper operation,
pressure test the radiator and cap.
4. AIR CLEANER FILTER REPLACEMENT* - Replace at
specified intervals. Ask your dealer for the proper replacement
intervals for your driving conditions.
5. FRONT WHEEL BEARING REPACK (%WHEEL DRIVE
ONLY) - Clean and repack the front wheel bearings at each brake
relining, or at the specified interval, whichever comes first.
