Proper equipment .must be used to prevent damage to vehicles during any
towing. State (Provincial in Canada) and local laws which apply to vehicles in
tow must be
followed. Get detailed towing instructions from your dealer.
Your vehicle
may be towed on all four wheels, at speeds less than 35 mph (60
km/h), for distances up to 50 miles (80 kilometers), provided the driveline and
steering are normally operable. For such towing, the steering must be unlocked, transmission in neutral and the· parking brake released. Connect to
main structural parts of the vehicle. Do NOT attach to bumpers or brackets.
Remember also that power assist for brakes and steering will not be available when the engine is off.
If the vehicle is to be towed by a wrecker, use only equipment designed for this purpose, following the instructions of the wrecker manufacturer. A safety Chain
system must be used for all towing.
FREEING VEHICLE FROM SAND, MUD, SNOW OR
ICE
If your vehicle gets stuck in sand, mud, snow or ice, move the shift lever on automatic transmission models from "0" (Drive) to "R" (Reverse) in a repeat
pattern.
Apply a light pressure to the accelerator pedal while the transmission is in gear. Remove your foot from the accelerator while shifting. Do not race
the engine. For best traction, avoid spinning the wheels. Incorrect rocking of your vehicle while it is stuck may result in damage to vehicle components.
CAUTION: Do not spin the wheels faster than 35 mph (55 km/h). Personal injury and
damage (inCluding tire, transmission and/or rear axle failure) may result from excessive
wheel spinning.
If the vehicle remains stuck after several rocking attempts, seek other
assistance. Also see the Notice under '(Automatic Transmissions" in "Steering
Column-Controls," Section 2 of this manual.

The fuel cap is.behind the. rear license plate.
NOTICE: tt you need: to repWce the fuel cap, use only a cap with these same features as specifie your dealer.
The fuel tank filler cap has a "screw-on ratcheting type" feature .
• _ To remove -rotate cap counterclockwise to clear the inside of the filler
neck. This will allow any residual pressure to escape .
_ To install -reverse this procedure and tighten cap securely until a
"ratcheting ". clicking sound is heard indicating cap is on properly.
CATALYTIC CONVERTER
.Ttle .cal;!ly:tic converter is an emission control device added to the exhaust system,' to reduce exhaust gas pollutants. The converter contains
a ceramic material coated with noble metal catalysts. To prevent contamination
of the catalysts , unleaded gasol;"" must be used . Unleaded gasoline also
reduces spark plug louling. exhaust system corrosion and engine oil
deterioration.
The catalytiC converter requires the use of unleaded gasoline. Using leaded gasoline wilt cause --the converter to lose its effectiveness as an
emission control device. Leaded gasoline will also damage the Computer
Command Control, system oxygen sensor, which could affect emission control,
fuel economy . and drivability.
~,~.,y..'~,","~ ... :..., To help 'prevent damage:
1. Keep your engine properly maintained . Engine malfunctions involving the electrical, carburetion or ignition systems may result in unusually high
catalytic con verter and exhaust . sy~tem temperatures which, under
extreme malfunctioning conditions·, may ignite interior floor:"'covering
materials above the converter. Do not keep driving your vehicle if you
detect engine misfire, noticeable loss of performance ,or other unusual operating conditions. Instead. have it serviced promptly.
A properly maintained
engine will help avoid malfunctions that could damage
the converter.
~ will also help provide good emission control and fuel economy.
See the Maintenance Schedule , folder for information on inspecling and
maintaining the engine. exhaust system. and other components. .
2. Do not drive through or Idle or park your vehicle over combustible
materials, such as grass or leaves_ They could touch the hot exhaust
system and ignite.
3. Do not push or tow this vehiCle to start it. This may result in unusually
high catalytic converter and exhaust system temperatures which under
extreme conditions may ignite interior floor -covering material above the
converter.
Pushing or towing to start can also damage · the catalytic
converter itself.
Disregarding these
instructions could damage the cataly:tic converter. the
vehicle, or nearby property.

Your new vehicle has a special emission contrOl system, called the Computer
Command Control system. Some vehicleS sold in Canada also have the
Computer Command Control system. II your Canadian vehicle has a "CHECK
ENGINE" light,
it dOes have the Computer Command Control system.)
The Computer Command Control system monitors . the .exhaust stream with
an
oxygen sensor. Based on sensor signals, the electronic control module adjusts
the carburetor air-fuel ratio as needed. It is very important to use only
unleaded gasoline in vehicles equipped with the Computer COmmand Control
system . .Leaded gasoline will damage the oxygen sensor and may affect
. emission controL .
On
all vehicles with the COmpute r Command Control system, a "CHECK
ENGINE" ligtit
on the instrument panel is designed to come on during engine
starting, to
let you knowthe bulb .is working. (The light will stay on a'shdl1iime
after the. engine starts.) If. the light comes on while driving, service to the
Computer Command Control system may be. required. Although your vehicle
may
still be drivable,see yoyr dealer as SOon as possible for an inspection of
the system.
Continued
driving · Without having the Computer Command Control system
serviced could cause damage to the emiSsion control system. It could also aftect fuel economy and drivability. .. ..
ENGINE OIL AND FILTER RECOMMENDATIONS
Checking 011 Level ,>,-.. ,
The engine oil must be kept at the right level to. help assure proper lubrication
of your vehicle' .s engine.
It is the owner's responsibility to' cheCk the oil level at
regular': infervals '{such . 'as . "e~~Y"JHflLstop), according ·to ' the following instruct ions . It is normal for an engine-O to use Some oil, and most engines may
use
more oil when they are new . " .
• The best time to check' the engine Orffevel is when the oil IS warm, such as
during a
fuel stop. First, wait about 5 minutes for the oil to drain back to the oil pan. Then, pull out the dipstick on the side of the engine block (either
right or left). Wipe
it clean and. push the dipstick back down all the way.
Now,
pull out the dipstick and look at the oil level .on the dipstick.
Some dipsticks have "Add" and "Full" lines. Others are marked "Add lOt"
and "OperatlngRange ." In all cases, keep the oil level above the "Add" line_ Push the dipstick .oock down alilheway after taking the reading . Add oil , if needed . . .
• If you check the oil level when the oil is cold, do not iun the engine first.
The
cold oil will not drain back to the pan fast enough to give a tr ue oil
level. . .
Ch '
oosing the Right Quality on
Engine oils are labeled on'the containers with variOus API (Amercian Petroleum Institute) deSignations of·quality. Artewhigher-quality category of engine 011,
designation "SF", was introduced early in 1980. Be sure the oil you use has
the
API designation "SF," either alone or shown with other designations . Do not use oils labeled only SA, SB,SC, SO,' SE, CA, CB,CC, or CD; or oils
with a combination of any of these categories-like SE/CD.

Downloaded from www.Manualslib.com manuals search engine If you have to add coolant more than four times a year (either to the recovery
tank or to the radiator), see your dealer for a cooling system check.
NOTICE: If you use the proper quality antifreeze, there is no· need to add extra inhihitorsor additiveswtlich claim to improve-the system. They may be harmful to the proper operation of the system.
Cooling' System Service
The cooling system should be serviced at the intervals specified in Section A of
the Maintenance Schedule folder as follows:
1. Wash the radiator cap and filler neck with clean water. See step 1 of "Coolant Replacement" for the proper way to remove the radiator cap.
2. Check the coolant level in the radiator and have it tested for freeze
protection.
Add ethylene glycol antifreeze, if needed, to maintain freeze
protection at-3JOC (~$4°f).
3. Have the cooling system and radiator cap tested for a pressure capacity of 105. kPa (15psi). (The pressure cantle anywhere from 95 kPa, or 14 psi,
to 120
kPa, or 18 psi.) If a replacement cap is needed, use an AC cap, or
an equivalent cap, designed fof coolant recovery systems and specffied for
your model.
4. Tighten all radiator hose clamps ang heater hose clamps and inspect all
hoses. Replace the hOSes if they are swollen, "checked" or otherwise worn.
NOTICE: Take care when tightening the hose clamps at the radiator. Overtightening could bend or collapse the radiator fittings.
5. Clean the front of the radiator core and air conditioning condenser to
remove dirt and other objects. Also clean the auxiliary engine oil andlor
transmission fluid cooler if the vehicle has them.
Coolant Replacernent
At the intervals specffied in Section A of the Maintenance Schedule folder, flush
9r1d refill the cooling system as follows:
1. Remove the radiator cap when the engine is cool:
•
Turn the cap slowly to the left until it reaches a "stop." Do not press
down while turning the
cap.
• Wait until any remaining pressure (indicated by a hissing sound) is
relieved, then press down on the cap and continue turning it to the left.
CAUTION: To help avoid the dangarm being burned. donotrem_ove the radiator cap While the engine' and radiator are. still. hot. Scaldingftukland steam ean be blown out under ~re It the cap is taken off too SOOf1.
2. When the cap is removed, run the engine until the upper rad.iator hose is
hot.
(ThiS shows that th~ thermostat is open and the coolant is flowing
through the system.)
3. Stop the engine. Open Ihe,actialor drain valVE! to drain the coolant. Drainage may be speeded by removing the drain plugs in the block, ff so
equipped.

Downloaded from www.Manualslib.com manuals search engine 4. Close the drain valve. Install the block drain plugs, if removed. Add water
until the system is
filled and run the engine until the upper radiator hose is
hot
again.
5. Repeat steps 3 and 4 several times until the drained liquid is nearly colorless.
6. Drain the system, then close the radiator drain valve tightly. Install block
drain plugs, if removed.
7. Disconnect all hoses from the coolant recovery tank. Remove the recovery
tank
and pour out any fluid. Scrub and clean the inside of the recovery
tank with soap and water. Flush it well with clean water, then drain it.
Reinstall the recovery tank and hoses.
8. Add enough water and ethylene glycol antifreeze (meeting GM
Specification 1899-M) to provide the required cooling, freezing and
c()rrosion protection, Use a solution that is at least 50 percent antifreeze out no mOre than 70 percent antifreeze. Fill the radiator to the base of the
filler neck
and fill the coolant recovery tank to the "Full Hot" mark. Put the
recovery tank cap back on.
9. Run the engine, with the radiator cap removed, until the upper radiator
hose is hot.
10. With the engine idling, add coolant to the radiator until it reaches the
bottom of the filler neck. Install the radiator cap, making sure the arrows on the cap line up with the overflow tube.
iI is the owner's responsibility to,
'. -Main)!!!n cooling system freeze protection at -3rC (-34'F) to ensure protection against corrosion and loss of coolant from boiling. (A 50/50
mixture of water and ethylene glycol antifreeze will provide freeze
protection to -37'C or -34'F.) You should do this even if you don't
expect freezing temperatures.
• Add ethylene glycol base' antifreeze that meets GM Specification 1899-M
when antifreeze haS to be added because of coolant loss or for more
protection against freezing at temperatures lower than -37'C (-34'F).
NOTICE: Do "otute methanol-base antifreeze, Of alcohol,or plain water alone, in your vehicle at any time. They will boil at a lower point than that at which the "TEMP"
light (or temperature gage) will warn of overheating,. and they do not provide proper protection against cOrrosion.
Radiator Pressure Cap
The radiator cap, a 105 kPa (15 psi) pressure type, must be installed tightly,
otherwise coolant may be lost and damage to engine may result from
overheating. Radiator pressure
caps should be checked periodically for proper
operation. If replacement is required, an AC cap is recommended.
Thermostat
The engine coolant temperature is controlled by a thermostat. It stops coolant
flow
through the radiator until a preset temperature is reached. This thermostat
is installed in the engine
coolant outlet on the engine block. The same thermostat is used in both winter and summer. When a replacement is needed, AC"Delco parts are recommended.
