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.

The horn on your vehicle is actuated by firmly pressing on the ped in the
center of the steering
wheel.
HAZARD WARNING FLASHER
The hazard warning flasher is covered in "In Case of Emergency," Section 3.

range of driving cond~ions even when the vehicle is loaded to ~ lull rated
vehicle toad capacity .

Brake Warning lJg/rt
The brake system warning light is covered in the '.' lnstrumentPanel" section.
Vacuum Power Brakes
• the engine stops, do not pump the brakes. The system is designed to stop the vehicle with reserve power assist n the brake pedal is held dOwn. This
reserve is
greatly reduced each time you apply and release the brakes. II,
when you turn the atMring wheel during braking, the vehic:1e does not turn, don't push as hard on the brake pedal •.
Without power assist the vehicle can still be stopped by pushing much harder
on the brake
pedal. however. the stopping distance may be longer.
Brakes (Except ,Parking Brake)
H the brake pedaJ goes down farther than normal, ~ may be due to a lack of
adjustment of any rear drum
brakes. To find. out if this is the case. drive
backward and forward a few times. applying the brakes firmly when going in
each direction.
See your dealer n pedal height dOes not retum to normal, or there is a rapid
increase in pedal travel whether or not your vehicle has rear drum brakes. This
could be a sign of brake trOUble.

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 .
