Downloaded from www.Manualslib.com manuals search engine You can be injured and your vehicle could be
damaged if
you try to do service work on a
vehicle without knowing enough about it.
0 Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before
you attempt any vehicle
maintenance task.
0 Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused. If you use
the wrong fasteners, parts can later break
or fall off.
You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the aifflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your Chevrolet dealer before adding equipment
to the
outside of your vehicle.
Fuel
Use regular unleaded gasoline rated at 87 octane or
higher. At a minimum, it should meet specifications
ASTM
D4814 in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association (AAMA) for better vehicle performance
and engine protection. Gasolines meeting the AAMA
specification could provide improved driveability and
emission control system protection compared to
other gasolines.

Downloaded from www.Manualslib.com manuals search engine Be sure the posted octane is at least 87. If the octane is
less than
87, you may get a heavy knocking noise when
you drive. If it’s bad enough, it can damage your engine.
If you’re using fuel rated at 87 octane or higher and you
hear heavy knocking, your engine needs service. But
don’t worry if you hear a little pinging noise when
you’re accelerating or driving up
a hill. That’s normal,
and you don’t have to buy a higher octane fuel to get rid
of pinging. It’s the heavy, constant knock that means
you have
a problem.
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label),
it is designed to operate on fuels that meet California
specifications.
If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on your instrument panel
may turn on and/or
your vehicle
may fail a smog-check test.
If this occurs, return to your
authorized Chevrolet dealer for diagnosis to determine
the cause of failure. In the event it is determined that the
cause of the condition is the type of fuels used, repairs
may not be covered by your warranty.
Some gasolines that are not reformulated for
low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl
(MMT);
ask your service station operator whether or not his fuel
contains MMT, General Motors does not recommend
the
use of such gasolines. If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be affected.
The
malfunction indicator lamp on your instrument panel
may
turn on. If this occurs, return to your authorized
Chevrolet dealer for service.

Downloaded from www.Manualslib.com manuals search engine To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to
add anything to the fuel. In addition, gasolines
containing oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that
you
use these gasolines if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may
be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by
use of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where
you’ll be driving.
You can also write
us at the following address for
advice. Just tell us where you’re going and give your
Vehicle Identification Number (VIN).

It’s a good idea to check your engine oil every time you
get fuel. In order
to get an accurate reading, the oil must
be warm and the vehicle must
be on level ground.
Check the oil here
if you
have a 2.2L engine,
Check the oil here if you have a 2.4L engine. The
dipstick’s handle will be a yellow ring.
Turn
off the engine and give the oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show the actual level.

The air cleaner is located on the driver’s side of the
engine compartment near the battery.
To check or replace the filter, remove the screws that
hold the cover on and lift the cover. Be sure to reinstall
the air cleaner filter and replace the cover tightly.

Operating the engine with the air cleaner off
can cause you or others to be burned. The air
cleaner not only cleans the air, it stops flame
if
the engine backfires. If it isn’t there, and the
engine backfires, you could be burned. Don’t
drive with it
off, and be careful working on the
engine with the air cleaner
off.
NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.
Automatic Transaxle Fluid
(Except
2.4L Code T Engine)
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90 OF (32 O C) or higher.
0 In hilly or mountainous terrain.
When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If
you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
See “Scheduled Maintenance Services” in the Index.

Downloaded from www.Manualslib.com manuals search engine Because this operation can be a little difficult, you may
choose to have this done
at your Chevrolet dealership
Service Department.
If you do it yourself, be sure to follow all the instructions
here, or you could get
a false reading on the dipstick.
NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine parts
or exhaust system parts, starting a fire. Be sure to
get an accurate reading if
you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
0 When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180°F to 200" F
(82°C to 93°C).
Get the vehicle warmed up by driving about
15 miles
(24 km) when outside temperatures are above 50°F
(10°C). If it's colder than 50°F (lO"C), you may have
to drive longer.
