Fuel
Use of the recommended fuel is an important part of the
proper maintenance of your vehicle.
Gasoline Octane
Use regular unleaded gasoline with a posted octane
of
87 or higher. If the octane is less than 87, you may
get a heavy knocking noise when you drive. If this
occurs, use a gasoline rated at
87 octane or higher as
soon as possible. Otherwise, you might damage
your engine. A little pinging noise when you accelerate
or drive uphill is considered normal. This does not
indicate a problem exists or that a higher-octane fuel is
necessary. If you are using
87 octane or higher-octane
fuel and hear heavy knocking, your engine needs
service.
Gasoline Specifications
It is recommended that gasoline meet specifications
which were developed by the American Automobile
Manufacturers Association and endorsed by the
Canadian Vehicle Manufacturers Association for better
vehicle performance and engine protection. Gasoline
meeting these specifications could provide improved
driveability and emission control system performance
compared
to other gasoline.
In Canada, look for the
“Auto Makers’ Choice”
label on the pump.
Canada Only

California Fuel
If your vehicle is certified to meet California Emission
Standards (see the underhood emission control label),
it is designed
to operate on fuels that meet California
specifications.
If this fuel is 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 may
turn on (see
Malfunction lndicator Lamp on page 3-31)
and your vehicle may fail a smog-check test. If this
occurs, return to your authorized GM dealer for
diagnosis.
If it is determined that the condition is caused
by the type of fuel used, repairs may not be covered
by your warranty.
Additives
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent engine and fuel system deposits from forming,
allowing your emission control system to work
properly. You should not have to add anything to your
fuel. Gasolines containing oxygenates, such as
ethers and ethanol, and reformulated gasolines may be
available in your area
to contribute to clean air. General Motors
recommends that you use these
gasolines, particularly
if they comply with the
specifications described earlier.
Nofice: Your vehicle was not designed for fuel that
contains methanol. Don’t use fuel containing
methanol. It can corrode metal parts in your fuel
system and also damage the plastic and rubber
parts. That damage wouldn’t be covered under your
warranty.
Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. General Motors does
not recommend the use of such gasolines. Fuels
containing MMT can reduce the life of spark plugs and
the performance of the emission control system may
be affected. The malfunction indicator lamp may turn on.
If this occurs, return to your authorized GM dealer for
service.

Checking Things Under
the Hood
Hood Release
To open the hood, do the following:
1. Pull the handle located
under the instrument
panel on the drivier's side
of the vehicle.
L% 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.
Things that burn can get on hot engine parts
and start
a fire. These include liquids like fuel,
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.

Engine Oil
LOW
Ole
3400 V6 Engine Only
If the LOW OIL light
appears on the instrument
cluster, it means you
need to check your engine
oil level right away.
Checking Engine Oil
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.
For more information, see
Low Oil Level Light on
page 3-35.
You should check your engine oil level regularly; this is
an added reminder.

3400 V6 Engine
The engine oil dipstick handle is yellow. The dipstick on
the
2.2L L4 ECOTEC engine is located at the front of
the engine compartment. The dipstick on the 3400
V6 engine is located at the front of the engine, behind
the fan. See
Engine Compartment Overview on
page 5-12 for more information on location.
Turn
off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil
dipstick might not show the actual level.
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
