Downloaded from www.Manualslib.com manuals search engine The upper knob changes the air temperature. Turn the knob clockwise for
warmer air. Turn the knob counterclockwise for cooler air.
The lower knob selects the heater
or air conditioning function and
determines which outlets the air will flow through (instrument panel,
defroster, heater, etc
.).
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.
MAX A/C - Air inside your vehicle is recirculated to maximize your air
conditioner’s performance and your vehicle’s fuel economy. This setting
cools the air the fastest and should be used to keep “unwanted odors” and/or
dust from entering the vehicle.
NORM A/C - This setting cools outside air and directs it through the
instrument panel vents. This setting is useful for normal cooling on hot
days.
BI-LEV A/C
- Air is delivered through the heater floor vents as well as
the instrument panel vents. This setting is useful in cool weather with bright
sunlight.
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. The air conditioner
does not run.
HEAT
- Heated air comes out through the heater floor vents and
windshield defroster vents. This setting is useful for cold weather.
BLEND
- Airflow is divided equally between the heater floor vent and the
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.
Engine Coolant Heater (Option)
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.

L
L
I‘ -a
Your vehicle’s ventilation system supplies outside air to the insi\
de 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 when 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 work far
better, reducing
the chance of fogging the inside of your windows.
0 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 inside
of
your windows.
0 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 Conditioning
Every now and then have your dealership check your air conditioning
system to be sure it has not lost any cooling ability. If you think\
the system
is not working properly, have your dealership check it out as \
soon as
possible.
The air conditioning will not work when the temperature is below
40°F
(4°C).
Lock Cylinders
To be sure your locks operate properly, they must be lubricated.
Refer to the Maintenance Schedule to determine how often to lubricate them
and what type
of lubricant to use.
You should not
use penetrating oils because they could wash out me factory
installed lubricant and cause the lock to bind. De-icers which \
contain
alcohol could also wash away the lubricant,
so be sure to lubricate the lock
after using a de-icer of this type.
Exhaust System
To help prevent damage to your exhaust system, do not continue to drive
your vehicle
if you notice:
0 Engine misfiring
0 Loss of performance
0 Exhaust system components hanging lower than normal.
0 Loud exhaust system noises.
0 Other unusual operating conditions
Have your engine and exhaust system serviced regularly.
Three-way Catalytic Converter
Your vehicle’s three-way catalytic converter is designed to reduce \
the
pollutants in your vehicle’s exhaust. Use only unleaded fuel in your vehicle.
If you use leaded fuel, you could damage your three-way catalytic converter
and other engine components.
Engine Control Module System
This system has an oxygen (02) sensor that helps keep your engine’s
air-fuel mixture at a proper level. Use only unleaded fuel
in your vehicle. If
you use leaded fuel, you could damage your oxygen (02) sensor and affect
your vehicle’s emissions.

TYPE
R134a
*All Quantities Are Approximate
QUANTITY*
30 oz. (.85 kg)
NOTICE:
R134a refrigerant is not compatible with R-12 refrigerant in an
air conditioning system. R-12 in an R134a system will cause
compressor failure, refrigerant oil sludge, or poor air
conditioning system performance.
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.
