Service
Your retailer knows your vehicle best and wants you to
be happy with it. We hope you’ll go to your retailer for
all your service needs. You’ll get genuine GM parts and
GM-trained and supported service people.
We hope you’ll want to keep your GM vehicle
all GM.
Genuine GM parts have one of these marks:

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want to use the proper Oldsmobile Service Manual.
It
tells you much more about how to service your vehicle
than this manual can.
To order the proper service
manual, see “Service and Owner Publications” in
the Index.
Your vehicle has an
air bag system. Before attempting to
do your own service work, see “Servicing Your Air
Bag-Equipped Vehicle” in the Index.
You should keep a record with all parts receipts and list
the mileage and the date
of any service work you
perform. See “Maintenance Record” in the Index.

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.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “Ehglish” 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 airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your retailer 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 (MA) 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.
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.

I

I If your vehicle is certified to meet California Emission
j Standards (indicated on the underhood emission control
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
1 vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
1 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 Oldsmobile retailer for diagnosis to
determine the cause of failure. In the event it is
1 determined that the cause of the condition is the type of
1 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 i may turn on. If this occurs, return to your authorized
i Oldsmobile retailer for service, To
provide cleaner
air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forrning
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 Filling Your Tank
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

Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don’t smoke
if you’re near gasoline or refbesng
your vehicle. Keep
sparks, flames and smoking
materials away from gasoline.

The cap is behind a hinged door on the right side of your
vehicle.
To open the door, insert your finger into the
finger depression next to the fuel door.
While refueling, hang the tethered cap inside the
fuel door. To
remove the cap,
turn it slowly to the left
(counterclockwise). The cap has a spring in it;
if you let
go of the cap
too soon, it will spring back to the right.
If you get gasoline on yourself 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 Iikely in
hot weather. Open the fuel filler cap slowly and
wait for any 6'hisss' noise to stop. Then unscrew
the cap all the
way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon
as possible. See "Cleaning the
Outside
of Your Vehicle" in the Index.

Checking Things Under the Hood
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 gasoline,
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.
Hood Release
The following sections tell you how to check fluids,
lubricants
and important parts under the hood.
To
open the hood, first pull
the
HOOD release handle
inside the vehicle.

Then go to the front of the vehicle and lift the secondary
hood release handle before
lifting.
Lift the hood, release
the hood prop
from its
retainer and put the hood
prop rod
into the slot
~ marked PROP ROD.
Before closing the hood, be sure all the filler caps
are on properly. Then let the hood drop from about
8 to 12 inches (20 to 30 cm).
