proper replacement parts and tools before you attempt any
vehicle maintenance task.

FUEL
Use regular unleaded gasoline rated at 87 octane or higher. It should
meet specifications
ASTM D4814 in the U.S. and CGSB 3.5-92 in
Canada. These fuels should have the proper additives,
so you should not
have to add anything to the fuel.
1 the U.S. and Canada, it’s easy to be sure you get the right kind of
gasoline (unleaded). You’ll see
“UNLEADED” right on the pump. And
only unleaded nozzles will fit into your vehicle’s filler neck.
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 still 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.
What about gasoline with blending materials that contain oxygen, such as
MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.’’ Fuel that is no more than
15%
MTBE is fine for your vehicle.
Ethanol is ethyl or grain alcohol. Properly-blended fuel that is no more
than
10% ethanol is fine for your vehicle.
Methanol is methyl or wood alcohol.
Gasolines for Cleaner &r
.. -- Your use of gasoline with detergent additives will help prevent deposits
from forming in your engine and fuel system. That helps keep your
engine
in tune and your emission control system working properly. It’s
~ good for your vehicle, and you’ll be doing your part for cleaner air.
Many gasolines are now blended with materials called oxygenates.
General Motors recommends that you use gasolines with these blending
. materials, such as MTBE and ethanol. By doing so, you can help clean
the air, especially in those parts of the country that have high carbon
monoxide levels.
c- In addition, some gasoline suppliers are now producing reformulated
- gasoline. By doing so, you can help clean the air, especially in those parts
gasolines.
These gasolines are specially designed to reduce vehicle
emissions. General Motors recommends that you use reformulated
of the country that have high ozone levels.

Downloaded from www.Manualslib.com manuals search engine You should ask your service station operators if their gasolines contain
detergents and oxygenates, and if they have been reformulated to reduce
vehicle emissions.
FUELS IN FOREIGN COUNTMES
If you plan on driving in another country outside the U.S. or Canada,
unleaded fuel may be hard to find.
Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can
corrode, and your engine
oil can deteriorate quickly. Your vehicle’s
oxygen sensor
will be damaged. All of that means costly repairs that
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).

A CAUTION:
Gasoline vapor is highly flammable. It burns violently, and that
can cause very bad injuries. Don’t smoke if you’re near gasoline
or if you’re refueling your vehicle. Keep sparks, flames, and
I
smoking materials away from gasoline.
c_ If you’re refueling your tank using a hydrocarbon recovery nozzle, the
fuel pump may shut off before the fuel capacity of your tank reaches full.
This is a normal condition. If you slow the
flow of fuel going into the
tank, it is more likely to fill to capacity without shutting off.
__
Locking Fuel Filler Door (Option)
m Your vehicle may have the locking fuel filler door.
The cap is behind the license plate. Pull down from the top of the license
plate bracket door to open.

Downloaded from www.Manualslib.com manuals search engine The filler door is
locked and unlocked
every time you use the
I power door locks. If
pushing
the power lock _a
switch doesn’t unlock w
or lock the fuel filler
door, you can use the
manual lock release
lever,
in the trunk.
Move the lever to the
left to unlock the fuel
filler
door.
To take off the cap, turn it slowly to the left (counterclockwise).

A CAUTION:
If you get gasoline on you and then something ignites it, you
could be badly burned. Gasoline can spray out on you
if you
open the fuel filler cap too quickly. This spray can happen if
your tank is nearly
full, and is more likely in hot weather. Open
the fuel filler cap slowly and wait for any “hiss” noise to stop.
Then unscrew the cap all the
way.
When you put the cap back on, turn it to rhe rlgnt untu you near a

Hood Release
To open the hood, first
pull the handle inside
the vehicle.
Then
go to the front of
the vehicle and release
the secondary hood
release.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
An electric fan under the hood can start up and injure you even
when the engine is not running. Keep hands, clothing and tools
away from any underhood electric fan.
A CAUTION:
Things that burn can get on hot engine parts and start a fire.
These include liquids like oil, coolant, brake fluid, windshield
washer and other fluids, and plastic or rubber.
You or others
could be burned. Be careful not to drop or spill things that will
burn onto
a hot engine.
I
Before closing the hood, be sure all the filler caps are on properly. Then
just pull the hood down and close it firmly.
ENGINE OIL
If the “Low Oil Level” light on the instrument panel comes on, it means
you need to check your engine oil level right away. You should check your
engine oil
level regularly; the light is an added reminder.
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. c1
