Downloaded from www.Manualslib.com manuals search engine FUEL REQUIREMENTS
Your engine is designed to use Only unleaded gasoline. Unleaded gasoline
must be used for the emission control system to operate properly. Its use will
also reduce spark plug fouling, exhaust system corrosion and engine oil deterioration.
Using leaded gasoline can damage the emission control system and could result in loss of emission warranty coverage. The effectiveness of the catalyst in the catalytic converter decreases after use of as little as one tank of leaded
gasoline. Also, your vehicle may have the "Computer Command Control"
system, which includes an oxygen sensor. Leaded gasoline will damage the sensor, and deteriorate emission control. (For more information, see
"Computer Command Control System" in "Service and Maintenance," Section 5 of this manual).
Federal
regulations require that pumps delivering unleaded gasoline be labeled with the word UNLEADED. Only these pumps have nozzles which fit the filler neck of your vehicle's gasoline tank.
In the United States, Federal law also requires that gasoline octane ratings be
posted on the pumps. The octane rating shown is an average of Research (A)
octane number and Motor (M) octane number. In most parts of the United
States, you should use unleaded gasoline with an octane rating of at least 87. However, you may use unleaded gasoline with an octane fating as low as 85 in these high-altitude areas: Colorado, Montana, New Mexico, Utah, Wyoming,
northeastern Nevada, southern
Idaho, western South Dakota, and that part of
Texas which
is directly south of New Mexico.
Using
unleaded gasoline with an octane rating lower than stated above can
cause persistent, heavy "spark knock."
("Spark knock" is a metallic rapping
noise.) If severe, this can lead to engine damage. If you detect heavy spark
knock even when using gasoline of the recommended octane rating, or if you hear steady spark knock while holding a steady speed on level roads, have
your
dealer correct the problem. Failure to take steps to stop such knocking is misuse of the vehicle, for which Chevrolet is not responsible.
However, now and then you may notice light spark knock for a short time while
accelerating or driving up hills. This'is no cause for concern, becauseyou,,~et the greatest fuel economy benefit from the gasoline's octane rating when there
is occasional light spark knock. Using gasoline with a higher octane rating than
that which allows occasional spark knock is an unnecessary expense.
Gasoline/Ethanol Blends
Blends of unleaded gasoline and ethanol (grain alcohol) sometimes known as gasohol are available in some areas. You may use these blends in your
vehicle, if they are no more than 10 percent ethanol, without jeopardizing the New Vehicle and Emission Warranties. Be sure the gasoline-ethanol blend has
octane ratings no lower than those recommended for unleaded gasoline. Most
drivers
will not notice operating differences with blends of up to 1 0 percent
ethanol, but some may. In that case, your authorized dealer can make certain
adjustments, provided they
do not violate the Federal Emission Standards. If you are still not satisfied with ethanol-gasoline blend performance, you may
prefer
to use unleaded gasoline.

Downloaded from www.Manualslib.com manuals search engine Other Gasolinel Alcohol Blends
Some fuel suppliers sell gasoline containing alcohol without advertising the
presence of
alcohol or giving it a special name such as gasohol. " you are not
sure whether there is alcohol in the gasoline you buy, check with the service
station operator.
DO NOT USE gasolines containing methanol (methyl or wood alcohol) that do
not
also contain cosolvents and corrosion inhibitors for methanol. Also, DO NOT USE gasolines that contain more than 5 percent methanol even if they
contain
cosolvents and corrosion inhib~ors. Fuel system damage or vehicle performance problems resuHing from the use of such fuels is not the
responsibility
of Chevrolet and may not be covered under the new vehicle
warranties.
Mhough gasolines containing 5 percent or less methanol and appropriate
cosolvents and inhibitors for methanol may be suitable for use in your vehicle,
evidence of their suitability is as yet incomplete; therefore, Chevrolet cannot, at
this time, endorse their use.
NOTICE: Take care to not spill gasoline during refueling. Guolines containing alcohol can cause paint damage, whiCh may notba covered under the New Vehicle Warranty.
OPERATION IN FOREIGN COUNTRIES
All models are specifically bum to comply with United States Federal Regulations regarding environmental quality. To comply, unleaded fuel of
sufficient octane rating must be used. These
fuels may not be available in
other countries. "you intend to take your vehicle outside the U.S. or Canada,
contact the GM Overseas Service Section at the
following address, to find out
what you must
do in order to operate your vehicles in other countries, or for
additional information and a. copy of the applicable maintenance schedule.
General Motors Corporation, Overseas Service Section, 2-128 General Motors
Building,
Detroij, Michigan 48202, (313) 556-4862.
When
writing, please include:
•
the Vehicle Identification Number and
• the countries in which yOu plan to travel.
Before taking your vehicle to a foreign country, check to see if the proper fuel
is available. Most major oil companies or domestic auto clubs should have this
information. Foreign offices of major oil
COmpanies or auto clubs may also be
of
help.
Be aware that, use of leaded gasoline or use of fuel that has a lower octane
rating than is required by your
vehicle, will cause the emission control system to lose its effectiveness and can cause ,engine knock or serious engine
damage. Ne~her GM Overseas nor Chevrolet will be responsible for damage to
your
vehicle as a result of not USing the proper fuel.
IMPORTANT FACTS YOU SHOULD KNOW ABOUT FUEL
ECONOMY AND HOW
TO IMPROVE IT
How you drive, where you drive, and when you drive all affect how many
miles/kilometers you can get from a galion/liter of fuel. You can save fuel if
you avoid
"Jackrabbit" starts, maintain as constant a throttle position as traffic
conditions
allow once you have reached cruising speed, and avoid sudden
stops which waste energy in the form of heat generated in braking.

Downloaded from www.Manualslib.com manuals search engine Frequent short trips, excessive idling and use of the air conditioner in cool
weather (when "vent" would provide adequate comfort), all can contribute to
decreased fuel economy .
The careful attention you give your vehicle as far as maintenance and repairs
are concerned will also help fuel economy . Proper engine and air cleaner
maintenance, lubrication intervals, wheel alignment and tire inflation pressures, when closely adhered to, will pay dividends in improved fuel economy as well as longer vehicle Irte.
Fuel Selection
Use only unleaded gasoline meeting the octane ratings given under "Fuel Requirements " in this section of the manual. Unleaded gasoline must be used
for the
emission control system to operate properly . Leaded gasoline will
damage the Computer Command
Control system oxygen sensor (if so equipped) and affect emission control. Using leaded gasoline can also damage
other parts of the emission control system and could result in loss of emission warranty coverage.

Front disc brake pads have buin-in wear indicators which should make a high­
pitched squealing or cricket-like warning sound when the brake pads are worn
to where new pads are needed . The sound will oome and
go. or be heard all the time when the vehicle is moving and when the brake pedal is pushed down
firmly. Expensive rotor damage can result if pads are not replaced when needed. See also the brake checks listed in the Maintenance Schedule folder.
INSTRUMENT PANEL AND CONTROLS
INSTRUMENTS
The instruments . gages and indicator lights conveniently grouped in the
instrument
cluster are designed to tell you at a glance many important things
about the performance of your Vehicle . The following information will enable
you to more quickly understand and properly interpret these instruments.
Speedometer
The speedometer hand indicates vehicle speed in miles per hour and
kilometers per hour.
Odometer
The group of figures in' the speedometer lower center section indicates the
accumulated mileage or kilometers .
Tamper-Resistant Odometer
Federal law prohibits tampering with vehicle odometers to aner accumulated
mileage. For your protection the odometer of this vehicle is designed with
tamper-resistant features to indicate
tarnpetiog . " silver lines appear vertically
between odometer numerals. it Is likely that the odometer has been turned
back or reversed . The mileage shown may not be actual. .
Whenever a new odometer is installed and cannot be set to the same mileage registered on the prior odometer . the law requires the owner to install a label
on thedriver's door frame to show the previous odometer reading and the date
of rep~. The · replacement odometer must then be set to zero . To
determine the actual vehicle
mileage. add the mileage shown on the label to . the current odometer reading. If the replacement odometer can be set up to
the same mileage as the prior odometer. no door frame
label is needed.
Trip Odometer
A trip odometer is used to record mileage on trips or during extended driving.
The trip odometer can be reset to zero by pushing the knob located in the
speedometer /odometer face until all zeros appear.
Fuei Gage
The fuel gage will register the APPAOXIMA TE fuel level in the tank. when the
ignition is in the RUN position .
When the gage registers EMPTY. some
fuel is still available as a reserve .
When the gage registers FULL. some additional fuel can still be added to the
tank . The fOllowing oonditions may be oonsidered normal:
•
Fuel station pump may shut off before fuel gage indicates FULL .

Downloaded from www.Manualslib.com manuals search engine Have the system repaired n the "CHECK ENGINE" light does not come on during engine starting. If the light comes on, either intermittently or
continuously while driving, service to the Computer Command Control system
is required. AHhough in most cases the vehicle is drivable, and does not
require towing, see your authorized
dealer as soon as possible for service of
the system.
Continued driving without having the Computer
Command Control system serviced could cause damage to the emission control system. It could also affect fuel economy and drivability.
See also "Computer Command Control system" in Section 5 of this manual.
Brake System Warning Light
The regular braking system is a dual system designed so that one part will
provide some braking if there is a
loss of hydraulic pressure in the other part of
the system. The system has a
"BRAKE" warning light located in the
instrument panel. The "BRAKE" light is designed to come on briefly during
engine starting so you can check that the bulb is okay. To serve as a reminder,
the
light should stay on when the parking brake is not fully released and the
ignition is
on. Have the system repaired if the light does not come on when it should. This warning light does not do away with the need for brake inspection
and maintenaflce. The brakelluid level must be checked regularly. See your
Maintenance Schedule folder for other brake checks.
I! the light remains on aller engine start up or comes on during operation of the vehicle, it may mean that there is something wrong with part of the brake
system.
What
to do:
1. Check to see that the parking brake has been released. I! it has been:
2. Pull off the road and stop carefully. Remember that:
• Stopping distances may be longer.
•
You may have to push harder on the pedal.
•
The pedal may go down farther than normal.
3. Tryout the brakes by starting and stopping on the road shoulder--then:
• I! you judge it to be safe, drive cautiously at a safe speed to the
nearest dealer for repair. Or,
• Have vehicle towed to the nearest dealer for repair.
Continued driving without getting necessary repairs
could be dangerous.
Tachometer
The optional tachometer indicates the speed of the engine in revolutions per
minute. The indicated number, times
100, gives the engine speed. Operating
the engine with the tachometer reading in the color-coded high-speed area
could lead to serious engine damage.
Voltmeter
When the engine is operating, the voltmeter indicates the electrical system
voltage. During minimum electrical load, the pointer will read to the right of the
center.
As the electrical load is increased, or in stop-and-go driving, the pointer
will rotate to the Ieli. A meter reading continuously in the left or right zone
indicates
an electrical system failure. Cause of the failure should be determined and corrected.
