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.
2-6

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.

2. If the engine has been flooded with too much fuel, it may start to run but
not have enough power to keep running .
In that case, continue cranking
with the
accelerator pedal all the way to the floor until the engine clears itseW of excess gasoline and runs smoothly . (But, do not crank more than
15 seconds at a time or you could damage the starter .)

(00 this with EITHER an automatic or manual transax)e.) Do not hold the brake ~I down too Iorig or too otten white going down • steep or long grade. This COUld ceu" the brakes to get hot and not work as well. As • result, the vehicle will not slow down at the usual r.t.~ Failure to u.ke these steps could r8l,,1t in. Iou of vehicle control.
DRIVING ON. SUPPERY SURFACES
While driving on a slippery surface avoid sudden acceleration, or engine
braking actions (due to shifting to a lower gear), which could cause the wheels
to skid . Skid correction is called for at these times.

Automatic Iransaxles replace the standard clutch and Iransaxle . After starting
the engine with the selector lever in "N" (Neutral) or "P" (Park) posnion,
select the range desired (see table) and depress the accelerator. A gradual start with a steady increase in ac ce lerator pressure will result in best possible
fuel economy. Rapid acceleration for fast starts will result in greater fuel consumption.
P -(PARK)

position together with the parking brake.
R - (REVERSE) This position
is used fot backing the vehicle.
" Bring your vehicle to a complete stop before
shifting to Reverse .
N - (NEUTRAL)
This is the out-of.gear position. You may restart
a stalled engine while the vehicle
is still moving
with the selector
"in Neutral. This position is also used when towing the vehicle. See the "In Case of Emergency" section for towing facts.
D

Forced downshifts -with the selector in "D"
you can get an automatic downshift at speeds
under
3S mph (60 km/h) by pressing Ihe accel· erator pedal approximately halfway to the 1I00r.
You
will also get a forced downshift at speeds
above 35 mph
(60 km/h) by pressing the
pedal all the way to the 1I00r . This will give
you increased acceleration for passing maneuvers.
2 - (LOW2) This range is used when extra performance is
required for hill climbing or it can also be used to provide "engine braking" to slow the vehicle
when going down medium grades. The shift lever may'be moved from "D" to "2n(and vice
versa) under most driving conditions.
1 - (LOWl) This position
is used to provide maximum engine
braking
when driving down very sharp grades
or when maximum performance is required
to
climb a steep hill or run through deep snow or
mud. You may shift into 1 at any speed but the
transaxle " will not lock into Low until vehicle
speed
is under 40 mphl.60 km/h).

I~ ,
Automatic transaxle shift quadrants of all GM vehicles continue the uniform
sequence of
selector positions. Shift indicators are arranged with "P"(Park) position at one end, followed in sequence by "R"(Reverse), "N"(Neutral) and
the forward driving ranges. All automatic transaxles are equipped with a starter
safety switch designed to permit starting the engine
only when the transaxle selector is in the "P"(Park) or "N"(Neutral) position. For additional engine
braking eftect,
as sometimes needed in mountainous driving, place the
transaxle in an intermediate or low range.
Your automatic transaxle has a clutch-type torque converter. The clutch is
designed to engage when the
vehicle reaches a steady speed aibove 25 to 45 mph (40 to 72 km/h). When engaged, the clutch provides a direct connection
between the engine and the drive wheels. This direct connection allows for
more efticient operation of the transaxle and thereby
helps contribute to
improved
fuel economy.
With the clutch-type converter,
you may notice some operational differences
compared to open-type automatic transaxle equipped vehicles. When the
clutch engages, for example, you may notice what feels like an extra transaxle
shift Also, on occasion, you may feel certain incidental engine pulSi'tions in the
30 to 50 mph (50 to 80 km/h) range. This feel is similar to that sometimes
experienced in a manual transaxle equipped vehicle. In addition, when the
accelerator
pedal is released abruptly, you may feel a slight impulse before the
clutch disengages.
These conditions
are normal. They have no adverse effect on your vehicle and
do not indicate the need for repairs.
Notice
The following practices could result in automatic transaxle failure:
• Shifting between forward and reverse driving range while operating the
engine at high speed or heavy throttle, such as when the driving wheels
are on snow or ice--commonly called "rocking." (See the correct method
for
"rocking" a vehicle under "Freeing Vehicle from Sand, Mud, Snow or
Ice" in "In Case of Emergency," Section 3 of this manual.)
•
Shifting to "R"(Reverse) or any forward range while operating the engine
at high speed in "N"(Neutral) or "P"(Park).
•
Shifting to "P"(Park) while the vehicle wheels are still turning.
• Operating the transaxle at or near "stall condition" for more than 1 0 seconds at a time. ("Stall condition" is when the engine is running at high speed while the transaxle is in a driving range and the drive wheels aren't
