Downloaded from www.Manualslib.com manuals search engine OPERATION IN FOREIGN COUNTRIES
All models which have the Computer Command Control system, (see "Service
and Maintenance," Section 5), are designed
to use unleaded gasoline as
specified under
"Fuel Requirements" in this section of the manual. Therefore,
these cars are not intended for use in areas where unleaded gasoline is
not readily available,
There also is a chance the gasolines available in some countries will not meet the needs of your gasoline engine even if it is not equipped with the Computer
Command Control system; Low~octane-ratedgasolines may cause engine pre­
ignition and serious engine damage, for which Chevrolet is not responsible.
In either case (with or without the Computer Command Control system), the
use of leaded gasoline will cause the emission control system to lose its
effectiveness.
It could also affect coverage· under the emission warranty. In
case of emergency, leaded gasoline may be used in your vehicle if unleaded gasoline is not available, but it should not be used exclusively. If you must use
leaded gasoline exclusively
in a vehicle designed for unleaded gasoline,
different maintenance intervals will be required. For additional information and
a copy of the maintenance schedule write to: Chevrolet Motor Division, Consumer Relations Department, Warren, Michigan 48090, (in Canada, write
to General Motors of Canada Limited, Customer Service Department, Oshawa,
Ontario
L 1J 5Z6).
When writing, please
include:
•
the Vehicle Identification Number and
• the countries in which you plan to travel.
Tires
If you plan to use your vehicle in countries where speeds over 75 mph (120
km/h) are allowed, see lIem3 on page 5-12.
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. The careful attention you give
your vehicle as far as maintenance and repairs are concerned
will also help
fuel economy.
Fuel Selection
Use only unleaded gasoline meeting the octane ratings given under "Fuel Requirements" in "Starting and Operating," Section 2 of this 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 and affect emission control. Using leaded gasoline can also
damage other parts of the emission control system and
CQuld result in 19s8 of
emission warranty coverage.
"Jackrabbit" Starts
You can save fuel (and prolong engine and tire life) by avoiding fast starts
away from lights and stop signs.
2-4

Downloaded from www.Manualslib.com manuals search engine Steady Cruising Speeds
Once you reach cruising sPeed, keep as steady a speed as road and traffic will allow . Speeding up and slowing down lessens your vehicle's efficiency and uses more fuel.
Stop-And-Start Driving
Frequent stops and starts while driving cut down on your miles per gallon
(kilometers per liter) . Plan even your short shopping trips to take advantage of
through streets to avoid traffic lights. Pace your driving
like the expert drivers
to avoid unneeded stops and braking .
Sudden Stops
Sudden stops can also waste fuel; instead of moving the vehicle, the energy of fuel is wasted as heat in braking. Energy in the fOrm of fuel is also needed to
accelerate
baCk to driving speed.
Excessive Idling
An idling engine uses fuel, too .. If you're faced with more than a minute wait,
and you're not in traffic , it may be better to turn off the engine and start again
later.
Lubricants
A well-lubricated vehicle means less friction between moving parts. See the Maintenance Schedule folder for the proper lubrication intervals.
Air Cleaner
Your vehicle receives its power from a mixture of fuel and air. The air enters
the engine through the air cleaner. A dirty air cleaner element lessens engine
perfOrrnance and can waste/Uel. ,So, it's important to replace the air cleaner
element (filter) at the intervals in Section C of the Maintenance Schedule folder .
Wind Drag
Open windows at high speeds cause "wind drag" which can lessen fuel
economy. Also, fuel economy is less when driving in crosswinds or headwinds .
To
help offset some of this loss, slow down when driving in these conditions.
Air Conditioner
" your vehicle has an optional air conditioner , use the "Economy, " ("Vent" or
"Heater") positions whenever possible. The air conditioner compressor, is not on in these positions and the reduced ,'engine-load can improve fuel economy.
Engine Maintenance
An engine that i. properly maintained ."iill provide better fuel economy than one
that is no\.
One misfiring spark plug will cut .fuel economy quite a bit, and will make a difference in the amount of pollution emitted from yOur vehicle.
Exces~ Weight
Fuel economy is related to the work. the engine must do. The heavier the load,
the more fuel it takes to run your vehicle. Keep weight to a minimum by taking
out any luggage or cargo when it is not needed.

Front disc brakes have bum-in we .ar indicators which are desigled to make a
high-pitched squeating or
cricket·tike warning sound when the brake pads are
worn to where new pads are needed . The sound will come
and go. or be heard
all the time when the wheels are rolling, but will stop when the brake pedal is
pushed down
firmly. Expensive 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 convenienlly grouped in the
instrument cluster are designed to tell you at a glance many important things
about the perform ance of your
vehicle. The following information will enabl e
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 six figures in the, speedometer lower center sectiori indicates the
accumulated mileage.
Trip Odometer (optional)
The trip odometer may be reset to zero by turning stem to. the right This
instrument may be used to 1TI<\':!1 .. aPC~rately record trip mileages 'or kilometers .
Fuel Gage
The fuel gage will register the APPROXIMATE 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 conditions maybe considered normal:
•
Gas station pump may shut off before fuel gage indicates FULL
• Amount of gasoline reqUired ior fill~up may not exaclly correspond to gage.
• Needle
may not move awa y from FULL until some time aiter 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.

Downloaded from www.Manualslib.com manuals search engine Chevrolet's turbocharger incUles a "TlI'bo Control Center," which is an
electronic,
closed- loop, high energy spark control system that permits the use
of today's compression ratios with unleaded fuels. It works to control spark and
provide
good driveability. H automatically compensates for fuel octane,
atmospheric conditions,
load, and .other driving conditions, by continually monitoring engine detonation and adjusting the spark.
Are There Any Tricks To Driving A Turbocharged V-61
No, riot at all. Starting procedures are as covered on Page 2-8.
As with any normal engine, the turbocharged engine should not be run at
excessive
RPM immediately upon starting or shut down abruptly after running
at high
speeds.
Trailer
Towing: It should be noted that the Turbo V-6 engine uses advanced
electronic technology to provide a combination of performance and fuel
economy under most operating conditions, including driving in high-altitude
areas . Uke 'most V-6 engines, ~is su~abIe for pul~ng light-dutytrailers up to
450 kilograms (1,000 pounds) gross weight. However, the system was not
engineered for the rigors of towing
heavytraii for
specffic recommendations) .
Don't Attempt Do-tt-Yourself Fixes: The turbocharger has but a handful of
parts, but since it is precision-manufactured with some tolerances as fine as
1/1 ,000,000 of an inch, maintenance and repairs should be done by an
authorized Chevrolet dealer or other qualified service outlet which
regularly
does such servk:e.
Catch Trouble Before . It Becomes Major: The turbocharger is an integral part
of your engine and not ar\'add-on .device.1f you spot an oil leak or hear an
unusual sound coming from the turbocharger , take it
In for service immediately .
The trouble may be simple to correct, but if allowed to continue, may
necessitate a more costly repair.
Normaf Scheduled Maintenance -
with Two Exceptions: The recommended
maintenance for the turbocharged
V -6 engine is shown in the General Motors
Maintenance
Schedule found in the glove compartment of your Chevrolet. The
turbocharged engine requires basically the same maintenance as a regular V-6
with two ",xceptions :
Engine Oil Change -every 3,000 miles.
Oil Filter Change -every 3,000 miles .
