STARTING AND OPERATING
ENGINE EXHAUST GAS CAUTION
(CARBON MONOXIDE)
CAUTION:-Do not breathe exhaust gas because it contains carbon monoxide, which by itself has no color crador. Carbon monoxide is a
dangerous gas. It can cause unconsciousness and can be lethal.
If at any time you think exhaust fumes are entering the vehicle, have the cause
determined and corrected as soon as possible. If you must drive under these conditions, drive only with ALL windows lully OPEN.
Protect against carbon monoxide entry into the vehicle body. The best way is
to keep the engine exhaust system,
vehicle body and body ventilation system
properly maintained. We recommend that the exhaust system and body be
inspected by a competent technician:
• each time the vehicle is raised for an oil change;
• whenever a change is noticed in the sound, of the exhaust system;
• whenever the exhaust system, underbody or rear of the vehicle is damaged
or becomes corroded.
See your Maintenance Schedule folder for parts requiring inspection.
To allow proper operation of your vehicle's ventilation system, keep the air inlet
grille in front of the windshield clear of snow, leaves or other obstructions at all
times.
DO NOT PARK WITH THE ENGINE RUNNING OR IDLE THIS VEHICLE FOR
MORE
THAN 10 MINUTES WITH THE VENTILATION SYSTEM CONTROL
SWITCH
IN THE "OFF" POSITION. EVEN WITH THE VENTILATION SYSTEM ON, RUNNING THE ENGINE WHILE PARKED OR STOPPED FOR LONGER
PERIODS OF TIME IS NOT
RECOMMENDED. ENTRY OF CARBON
MONOXIDE INTO THE CAR BODY IS POSSiBlE WITH A POORLY REPAIRED, DAMAGED, OR CORRODED EXHAUST SYSTEM OR BODY.
Do not run the engine in CONFINED areas (such as garages or next to a
building) any more than needed to move the vehicle. When the
vehicle has to
be stopped
in an UNCONFINED area with the engine running for any more
than a few minutes, take the following steps:
A. Adjust the heating or cooling system to force outside air into the vehicle as
follows:
1. On vehicles not equipped with air conditioning, set the fan to
intermediate or high speed and the upper control lever to any position.
2. On vehicles equipped with air conditioning, set the fan to an
intermediate or high speed and the upper control lever to any position
except
"OFF" or "MAX."
B. Keep the exhaust tailpipe area clear of snow and other material to help
reduce the buildup of exhaust gases under the vehicle. This is particularly
important when parked in blizzard conditions.

Downloaded from www.Manualslib.com manuals search engine Driving with the trunk lid, hatchback or liftgate on station wagon models open is not recommended. Under some conditions, exhaust gases may be drawn
into the vehicle. If the trunk lid, hatchback or liftback must remain open for
some reason while moving, or if electrical wiring or other cable connections to a trailer must pass through the seal between the trunk lid, hatchback or liftback
and the body, follow these precautions:
• Close all windows.
• Adjust the heating or cooling system to force outside air into the vehicle as
described abcve, but set the fan to high speed.
• On vehicles with outside air vents in or under the instrument panel, open the vents fully.
NEW VEHICLE "BREAK-IN" PERIOD
You can drive your new vehicle from its very first mile/kilometer without
following a formal "break-in" schedule. However, there are things you can do during the first few hundred miles/kilometers of driving that will add to the
future performance and economy of your vehicle.
We recommend you limit your speed during the first 500 miles (800 kilometers)
to a maximum of 55 mph (90 km/h); but do not drive for long periods at any
one constant speed, either fast or slow. During this time, avoid full throttle
starts and, if possible, avoid hard stops especially during the first 200 miles (320 kilometers) of driving.
Always drive at moderate speed until the engine has completely warmed up.
I! you plan to use your new vehicle for trailer towing, see the following.
TRAILER TOWING
This car is designed and intended to be used mainly to carry people. Towing a
trailer
will affect handling, durability and economy. Your safety and satisfaction
depend upon proper use of correct equipment. Also, you should avoid
overloads and other abusive use.
The maximum loaded trailer weight you can pull with your vehicle depends on
your intended use
and what special equipment has been installed on it.
Information on trailer towing ability, special equipment required, and optional
equipment available should be obtained from your dealer. Ask for the trailering brochure. Or, write: Consumer Relations Department, Chevrolet Motor
Division, Warren, Michigan 48090.
(In Canada, write to General Motors of
Canada Limited, Customer Services Department, Oshawa, Ontario L lJ 5Z6.)
Tires
When towing trailers, be sure your tires are properly inflated to the inflation pressure shown on the Tire Placard on the driver's door.
The allowable passenger and cargo load for this vehicle, also shown on the
Tire
Placard, is reduced by the trailer tongue weight whenever the trailer is
attached to the vehicle. See "Service and Maintenance," Section 5 for more tire information.
Maintenance
More frequent service is required when using your vehicle to pull a trailer. See
the Maintenance Schedule folder for Automatic Transaxle Fluid and Engine Oil change requirements for trailering.

Downloaded from www.Manualslib.com manuals search engine Now and then, check that all trailer hitch bolts and nuts are tight. Also see the
Maintenance
Schedule folder, and thelndax in this manual , for important facts
on
belts , cooling system care and brake ~tment.
Break-In Schedule
See the new vehicle break-in information in this manual. Also, we recommend
you drive your new vehicle for 500 miles (800 kilometers) before trailer towing.
At the end of this 500 mile (800 kilometer) break-in period, avoid speeds over
50 mph (80 km/h) and full throttle starts during the first 500 miles (800 kilometers) of trailer towing .
CAUTION:
BRAKES-To help avoid personal injury due to poor braking action :
•
Trailer brakes of adequate size are required on trailers more than 450
kilograms (1,000 pounds) loaded weight.
• If you use trailer brakes with this vehicle, follow the instailation and balance instructions of the trailer brake manufacturer.
• Do not tap into the vehicle's brake system iUhe trailer brake system uses
more than 0.3 cubic centimeter (0.02 cubic inches) 01 fluid from the
vehicle 's
mast.". cyllnd<1r .. , In this case, the vehicle's brake fluid capacity will not be enough to operate both thevehicte and trailer brakes under all kinds
of use.
• All brake fluid parts must be able to stand 20 650 kPa (3,000 psi) . The
brake fluid tap must be made at the upper rear master cylinder port.
Copper tubing is subject to fatigue failure and must not be used.
HITCHES-To help avoid personal injury due to sway caused by such things as
crosswinds, large trucks passing or road roughness , or due to separation of
the trailer :
• A properly installed and adjusted (1) frame mounted, weight-dstribut ing hitch and (2) sway control witheoough capacity are required for trailers
more than 900 kilograms (2,000 pounds) loaded weight.
• Keep the trailer tongue load at 10 percent of the loaded trailer weight for
dead-weight hitches and 12 percent for weight-distributing hitches. Tongue
loads can be adjusted by proper distribution of the load in the trailer. This
can
be checked by weighing separately the loaded trailer and then the
tongue .
• Do not use axle-mounted Mches. They can damage the axle housing , wheel bearings , wheels or tires.
• Do not allow steel hitch parts to be in direct contact with aluminum bumper
parts, if so equipped. When steel and aluminum are in contact, a galvanic
reaction (a form of corrosion) can occur which will progressively lessen the
strength of the contacting metals to the point
of failure. An organic
compound or paint should
be used as a barrier on the contacting surfaces
and on the attaching fasteners.
• When you remove a trailer hitch, be sure to seal any mounting holes in the body. This will help prevent entry 01 exhaust fumes, "Engine Exhaust Gas caution (Carbon Monoxide) " at the begiming of
"Starting and Operating ," Section 2 ollhis manual.)
2-3

Downloaded from www.Manualslib.com manuals search engine NonCE: Use only trailer hitches which permit normal operation of the Energy
Absorbing Bumper system, If so equipped. For example, a rigid fore and aft connection between the bumper and any other part of-the vehicle may increase damage in the event of a collision.
TRAILER TOWING TIPS
Getting Started
Before entering traffic with a trailer that has electric brakes, start the vehicle and trailer moving and apply the trailer brakes by hand to be sure the trailer
brakes are working and the trailer electrical system is connected.
Engine Cooling
If your engine overheats, follow the steps under "Engine Cooling System
Overheating" in "In Case of Emergency," Section 3 of this manual.
Long Uphill Grades
When going up long grades, you can reduce the chance 01 engine overheating
by turning off the air conditioner, if so equipped.
Down Steep Or Long Grades
Before going down a steep or long grade, reduce speed and shift the transaxle
into a lower gear to help control your vehicle's speed. Try not to hold the brake pedal down too long or too often. This could cause the brakes to overheat and
reduce brake effectiveness.
Transaxle
See the method for checking the transaxle fluid level in "Service and
Maintenance,"
Section 5 of this manual.
Parkin!!
You should not park vehicles with trailers on a grade (hill). However, if you
must park on a grade, these steps must be followed:
1. Apply the regular brakes.
2. Have someone place wheel chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb the load.
4. Apply the parking brake.
5. Shift the transaxle to "P"(Park),
If the vehicle is parked on a grade, don't shift the transaxle to "P"(Park) until the trailer wheels are chocked and the parking brake is set. If you do, the
weight of the
vehicle and trailer may put so much force on the parking pawl in
the transaxle that it may be hard to shift out of "P"(Park).
When starting, after being parked
on a grade:
1. Apply the regular brakes and hold.
2. Start the engine in "P"(Park).
3. Shift into gear and release the parking brake.
4. Release the regular brakes and drive until the chocks are free.
5. Apply the regular brakes and have someone remove the chocks.

• Needle may not move away from FULL until some time after fill-up.
• Needle may move during turns; stops and accelerations.
When the ignition switch is turned to the OFF position, the needle will not
necessarily return
all the way to the EMPTY mark.
Oil Pressure Light
When the ignition is turned to "Run," the "Oil" warning light appears until the
engine is started. Thereafter, the light should be off unless there is insufficient
oil pressure or engine idle speed is below normal. If the light should come on
at any time while driving (other than momentarily at idle speed or after a
sudden stop), stop immediately and investigate the cause of
low oil pressure.
This could possibly be caused by low oil level in the crankcase. Engine
operation with low oil pressure will 9ause damage to the engine.
Engine Coolant Temperature Light
This light is located in the instrument cluster and is designed to come on to warn the driver that the engine coolant has overheated and immediate
action is required to correct the condition. As a check that the bulb and its
circuit are working, the light will come on during engine starting; if it does not,
have it repaired
promptly. If the light comes on at any other time, see "Engine
Cooling System Overheating" in "In Case of Emergency," Section 3 of this manual.
CAUTION: It the Engine Coolant Temperature Light shows an overheat condition or you have other reason to suspect the engine may be overheating, continued operation of the engine EVEN FOR A SHORT TIME may result in a fire and the risk of personal injury and/or severe vehicle damage. Take immediate action as outlined under "Engine Cooling System Overheating" in "In Case of Emergency," Section 3.
Generator Indicator Light
The VOLT light is designed to come on when the ignition key is in the "RUN" position, but before the engine is started. After the engine starts, the light
should go out and remain out. If the light remains· on when engine is running,
have your authorized
dealer locate and correct the trouble as soon as possible.
Shift Indicator Light
The Shift Indicator Light is covered in the "Manual Transaxle" information in
this section.
"Check Engine" Light
Most gasoline engine vehicles sold in the Unijed States (and some vehicles
sold
in Canada) have the Computer Command Control system.
Vehicles with the Computer Command Control system include a "CHECK
ENGINE" light
on the instrument panel designed to indicate the need for
system service. It will come on during engine starting to let you know the bulb
is working. (The light will stay on a short time after the engine starts.)

Downloaded from www.Manualslib.com manuals search engine Engine Coolant Temperature Gage
This optional gage is located in the instrument cluster. If the gage shows that
an overheat condition exists-as indicated by pointer moving beyond the
center of the band immediate action by the driver is required. If an overheat
condition is shown, see "Engine
Cooling System Overheating" in "In Case of
Emergency,"
Section 3 of this manual. The coolant temperature indication will VaIY with air temperature and operating conditions. The ignition must be in
"Run" for accurate readings. Prolonged driving or idling in very hot weather
may cause the pointer to move beyond the center of the gage. Make a practice
of scanning this and other gages
while driving, especially in hot weather and!
or when the
vehicle is under load.
CAUTION: II the Engine Coolant Temperature Gage shows an overheat condition or you have other reason to suspect the engine may be overheating, continued operation of the engine EVEN FOR A SHORT TIME may result in a fire and the risk of personal injury and/or severe vehicle damage. Take immediate action as outlined under "Engine Cooling System Overheating" in "In Case of Emergency," Section 3.
Oil Pressure Gage
The oil pressure gage indicates the pressure at which oil is being delivered to
the vaIiOUS paIls of the engine requiring lubrication. Pressures registered by
the gage may
vBIY according to outside air temperatures or weight of oil being
used. Oil pressure of a cold engine being operated at a given speed will be
somewhat higher than when the engine is at normal operating temperature at
the
SaIne speed. Prolonged high speed operation on a hot day at the given
speed will
resuH in somewhatlower oil pressure readings. Readings of 205 to
275 kPa
(30 to 40 psi) may be considered normal during moderate road
speeds of 35 to 40 mph (55 to 60 km!h) with the engine at proper operating
temperature. Gage readings which are consistently high
or low under these conditions may indicate lubrication system and/ or engine malfunction.
Light Switch
The three· position light switch controls the headlights, taillights, paIking lights,
sidemaIker lights,
instrument lights and dome lights.
Instrument light intensity can be varied by turning knob clockwise or
counterclockwise. Full counterclockwise position turns on interior light.
The headlight circuit is protected by a circuit breaker in the
light switch. An overload on the breaker will cause the lights to "flicker" on and off. If this
condition
develops, have your headlight wiring checked immediately. The
headlight beaIn changer is located in the Turn Signal Lever; for operation see
Section 2 under heading "Turn Signal and Muiji-Function Lever."·
Headlight High Beam Indicator Light
The headlights of your vehicle have. high and low beams to provide you with
proper nighttime visibility for most driving conditions. The
"low" beams are
used during most city driving. The
"high" beams are especially useful when
driving on daIk roads since they provide long range illumination. The headlight
beam indicator light (located on the speedometer face) will be ON whenever
the high beams or "brights" are in use. The turn
signal lever controls the
headlight beaIns and is described in "Steering Column Controls."

with a small amount delivered to the windshield (defroster outlets). The air
temperature
Is controlled by the TEMPERATURE LEVER while the air
quantity
is controlled by the FAN LEVER. This position is used for most winter driving.
• BLEND -- The AIR SELECTOR LEVER may be adjusted between HEATER
and DEFROST positions to obtain a variable distribution of air between the
floor air outlet and the windsh ield defroster air outlets.
• Side window defogger air outlets direct air to the side windows whenever
the fan is operating.
•
DEFROST - -In this poSition, most of the air is delivered to the windshield
(defroster outlets) with a small amount
to the floor air outlet.
The windshield defrosting and defogging system assists in providing
good visibility through designated areas of the windshield under most inclement
weather conditions . For immediate operation of the vehicle, the windshield
should be scraped clear.
Operate system for 30 seconds before switching to DEFROST . This will
remove humid air from the system
and minimize rapid fogging of the glass
which can occur if humid air Is blown onto a cOol windshield .
AIR CONOmONING SYSTEM
This system combines heating and cOOling capabilities for comfort in all weather conditions.
During some air conditioning operating conditions, slight increases and
decreases of engine speed/power may be noticed . This
should be considered
normal, as the system is designed to cycle the compressor
ON and OFF to
maintain desired cooling. The reduced compressor operation should
benef~ fuel economy.
Fan Lever
The fan lever (LO-HI) provides speed control of the blower fan in all Air
Selector Lever positions except
OFF.
Temperature Control Lever
The femperature control lever regulates the temperature of the air entering the passenger compartment in All Air Selector Lever positions .
Air Selector Lever
The air selector lever regulates air flow from the heater, defroster and air
conditioning outlets.
It also controls operation of the refrigeration compressor.
•
OFF --In this position the blower does not operate . However, when the
vehicle is moving, air will enter the· passenger compartment through the
heater outlet.

outlets . This position. with the temperature
lever in full COLD. is used for
maximum cooling under conditions of high temperature and humidity .
• NORM (AIR COND) --Outside air is conditioned as ~ passes through the
system and is discharged from the upper outlets. This position is used for most air conditioning situations.
• BI-LEVEL (AIR COND) --Outside air is conditioned and directed out the
upper outlets PLUS the heater outlet. This position provides comfort and
keeps the windshield clear under low fogging conditions .
• VENT (ECONOMY) --Outside air is discharged from the upper outlet s. This position is provided for cool to moderate weather operation when
refrigeration is not required. The refrigeration compressor is turned off.
Operating Information -The engine cooling fan is automatically engaged in all air conditioning modes and defrost mode (with high air conditioning pressure).
• HEATER (ECONOMY) --Outside air is delivered from the heater outlet with
a small amount from the defroster outlets and the side window . defogger outlets. This position is used for most winter driving. The air conditioning compressor is turned off.
• DEFROST c_ Outs ide air is cond~ioned and delivered from the defroster
outlets w i1h a small amount from the heater outlet. This position is
recommended for conditions of severe fogging and icing
only.
Operating Tip
For satisfactory operation of the air conditioning system. windows should always be closed, except for the first two or three minutes to remove hot air if
the car has been closed. This provides a fast cool-down in normal air
conditioning mode.
ELECTRO-CLEAR REAR WINDOW DEFOGGER
The optional defogger consists of a heating element bonded to the inside
surface
of the rear glass . The unit is operated by a switch on the instrument panel and functions only in the ON position. When activated an indicator light
will illuminate.
After the defogger has operated for a short time. the system will
automatically shut off. If further defrosting or defogging is desired . simply actuate the switch again.
The defogger
will not function if the ignition is turned off.
Refrain from removing decals or other materjal' from the inside of rear window
with a razor or other sharp instrument since this may damage . the heating
element.
Clear snow and ice from the rear window to improve tihe efficiency of the rear
window defogger.

Downloaded from www.Manualslib.com manuals search engine ENGINE COOLING SYSTEM OVERHEATING
If you see or hear escaping steam or have other reason to suspect there is a
serious overheat condition, stop and park the vehicle as soon as it is safe
to do so and turn off the engine immediately and get out of the vehicle.
The cooling system may overheat if the coolant level is too low, if there is a
sudden
loss of coolant (such as a worn hose splitting), or if other problems occur. It may also temporarily overheat during severe operating conditions
such as:
• climbing a long hill on a hot day,
• stopping after high-speed driving,
• idling for long periods in trallic, or
• towing a trailer.
I! the Engine Coolant Temperature light comes on (or if you have an Engine
Coolant Temperature gage and it shows an overheat condition), or you have
any reason to suspect the engine may be overheating:
• tfyour air conditioner is on, turn it off.
• If you are stopped in traffic, shift the transaxle to "N" (Neutral).
If the warning light does not go off (or engine coolant temperature does not
start to drop) within a minute
Or two:
• Pull over, stop and park the vehicle as soon as it is safe to do so.
• Let the engine run at normal idle speed for two or three minutes.
I! the warning light does not go off (or engine coolant temperature does not
start to drop),
turn off the engine and get out of the car, then proceed as
follows:
CAUTION: To help avokt being burned:
• DO NOT OPEN ntE HOOD if you see or hear steam or coolant escaping from the engine compartment. Wait until no steam or coolant can be seen or heard before opening the hood.
• DO NOT REMOVE THE RADIATOR CAP or coolant RECOVERY TANK CAP IF THE COOLANT IN THE RECOVERY TANK IS BOIUNG. Also do not remove the radiator
cap while the engine and radiator are still hot Scalding fluid and steam can be blown out under pressure if eHher cap is taken off too soon.
I! no steam or coolant can be seen or heard, raise the engine hood. If the
coolant is boiling, wait until it stops before proceeding. Look at the
3-3

Downloaded from www.Manualslib.com manuals search engine coolant level in the see-through recovery tank. The coolant level should be at
or above the
"FULL HOT" mark on the recovery tank.
CAUTION: Keep hand., toots and clothing -away from the engine COOling fa", to help prevent personIl intUry. lhiIlan is electric and can come on whether Or not the engine Is rUnning. 111. tan can start automatically In .respon .. to a heat sensor when the ignition Is in "Run."
Make sure the water pu"",, belts are not broken, or off the pulleys , and that the fan runs when the engine is running and there is an indication on the instrument panel of an overheat condition.
If the coolant level in the recovery tank is low, look for leaks at the radiator
hoses and connections, heater hoses and connections, radiator I and water pump. If you find major leaks, or spot other problems that may have caused
the engine to overheat,
do not run the engine untilthese problems have been
corrected. If you do not find a leak or other problem, caretully add coolant to
the recovery tank. (Coolant is a mixture of ethylene glycol antifreeze and water; see "Engine Cooling System" in "'Service and Maintenance," Section 5, for the proper antifreeze and mixture.) .
CAUTION: Under: some:' conditione, the ethylen~ glycol In engine coolant Is . combustible. -To help avoid being burned, DO NOT spill antifreeze or coolant on the exhauat system or hot engine parts..
If the coolant level in the recovery tank is at the correct level but there is still
an indication on the instrument panel of an overheat condition:
•
You may add coolant directly to the radiator. YOU MUST LET ENGINE COOL FIRST. See "Coolant Replacement" under "Engine Cooling
System"
in Section 5, "Service and Maintenance" in this manual. Follow steps t through 3 for the correct way to remove the radiator
cap
and add coolant.
Once the Engine Coolant Temperature light has gone out (or the Engine Coolant Temperature gage no longer signals an overheat condition), you can
resume
driving at a reduced speed. Return to normal driving after about ten
minutes If the light does not come back on (or the gage pointer does not again
show
ao overheat condition).
tf no cause for the overheat condition was found, see a qualified service technician.
JACKING
CAUTION
To help avoid personal injury:
• FollOW all jacking and stowage instructions .
• Use jack only for lifting this vehicle during wheel change.
• Never get beneath the vehicle, start or run engine while vehicle is
supported by jack.
• Always securely restow spare tire (or flat tire) and all jacking equipment.
