NOTICE:
If you damage the covering for the driver’s or the
right front passenger’s air bag, the bag may not
work properly. You may have to replace the
air
bag module in the steering wheel or both the air
bag module and the instrument panel for the
right front passenger’s
air bag. Do not open or
break the
air bag coverings.
If your vehicle ever gets into a lot of water -- such as
water up to the carpeting or higher
-- or if water enters
your vehicle and soaks the carpet, the air bag controller
can be soaked and ruined. If this ever happens, and then
you start your vehicle, the damage could make the air
bags inflate, even
if there’s no crash. You would have to
replace the air bags as well as the sensors and related
parts. If your vehicle is ever in a flood, or if it’s exposed
to water that soaks the carpet, you can avoid needless
repair costs by turning off the vehicle immediately.
Don’t let anyone start the vehicle, even to tow it, unless \
the battery cables are first disconnected.

Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts
of the air bag system in several places
around your vehicle. You don’t want the system to
inflate while someone is working on your vehicle. Your
retailer and the Cutlass Service Manual have
information about servicing your vehicle and the air bag
system. To purchase a service manual, see “Service and
Owner Publications” in the Index.
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured
if you are close to an air bag when
it inflates. Avoid yellow connectors. They are
probably part of the air bag system. Be sure to
follow proper service procedures, and make sure
the person performing work for you
is qualified
to do
so.
The air bag system does not need regular maintenance.

Safety Belt Extender
If the vehicle’s safety belt will fasten around you, you
should
use it.
But if a safety belt isn’t long enough to fasten, your
retailer will order you an extender. It’s free. When you
go in to order it, take the heaviest coat you will wear, so
the extender will be long enough for you. The extender
will be just for you, and just for the seat
in your vehicle
that you choose. Don’t let someone else use it, and use it
only for the seat it is made to fit. To wear it, just attach it
to the regular safety belt.
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors and
anchorages
are working properly. Look for any other
loose
or damaged safety belt system parts. If you see
anything that might keep a safety belt system from
doing its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt is
torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system does not need regular maintenance.)
Replacing Restraint System Parts
After
a Crash
If you’ve had a crash, do you need new belts?
After a very minor collision, nothing may be necessary.
But
if the belts were stretched, as they would be if worn
during a more severe crash, then you need new belts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have safety belt
or seat parts repaired or replaced. New parts and repairs
may be necessary even if the belt wasn’t being used at
the time of the collision.
If your seat adjuster won’t work after a crash, the special
part of the safety belt that goes through the seat to the
adjuster may need to be replaced.
If an air bag inflates, you’ll need to replace air bag
system parts. See the part on the air bag system earlier in
this section.

Malfunction Indicator Lamp (Check Engine Light)
CHECK
Your vehicle is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
This system is called
OBD 11 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. The
CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before
any problem is apparent. This may prevent more
serious damage to your vehicle.
This system is also
designed to assist your service technician in correctly
diagnosing
any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after
a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
Modifications made to the engine, transaxle,
exhaust or fuel system of your vehicle or the
replacement of the original tires with other than
those
of the same Tire Performance Criteria
(TPC) can affect your vehicle’s emission controls
and may cause the light to come
on.
modifications to these systems could lead to
costly repairs not covered by your warranty. This
may also result
in a failure to pass a required
Emission Inspection/Maintenance test.

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.

As shown in the chart, SAE 5W-30 is best for your
vehicle. However, you can use
SAE 1OW-30 if it’s going
to be
0°F (-18°C) or above. These numbers on an oil
container show its viscosity, or thickness.
Do not use
other viscosity oils, such as
SAE 2OW-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst” symbol. Failure
to use the
recommended
oil can result in engine damage not
covered
by your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls below
-20°F (-29”C), consider using either an SAE 5W-30
synthetic oil or an
SAE OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don’t add anything to your oil. Your retailer is ready to
advise
if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:
0
0
0
0
0
Most trips are less than 5 to 10 miles (8 to 16 h).
This is particularly important when outside
temperatures are below freezing.
Most
trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer
or use a carrier on top of
your vehicle.
The vehicle
is used for delivery service, police, taxi
or other cornmercial application.
Driving under these conditions causes engine oil to
break down sooner. If any one of these is true for your
vehicle, then you need to change your oil and filter
every 3,000 miles (5
000 km) or 3 months -- whichever
occurs first.
6-15

If none of them is true, use the long triphighway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil
to
break down slower.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or
a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be a real threat to the environment.
If you
change your own
oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it
by taking it to a place that collects used oil. If
you have
a problem properly disposing of your used oil,
ask your retailer, a service station or a local recycling
center for help.
The air cleaner is located on the driver’s side of the
engine compartment.
To check or replace the air filter:
1. Unscrew the four Phillips-head screws, then pull the
cover back.
2. Remove the air cleaner filter.
3. Be sure to install the air cleaner filter and replace the
cover tightly.
6-16

Refer to the Maintenance Schedule to determine when to
replace the air filter.
See “Scheduled Maintenance Services” in the Index.
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
It is not necessary to check the transaxle fluid level. A
transaxle fluid leak is the only reason for fluid loss. If a
leak occurs, take the vehicle to your Oldsmobile retail
facility Service Department and have it repaired as soon
as possible. You may also have your fluid level checked
by your retailer or service center when you have your oil 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 h.aff.3~ where the outside temperature
0 In hilly or mountainous terrain.
When doing frequent trailer towing.
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.
regularly reaches
90°F (32” C) or higher.
6-17

Brake Wear
Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are
worn
and new pads are needed. The sound may come and go or
be heard
all the time your vehicle is moving (except when
you
are pushing on the brake pedal firmly).
The brake wear warning sound means that soon
your brakes won’t work well. That could lead
to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
I NOTICE:
~~ ~ ~~
Continuing to drive with worn-out brake pads
could result
in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque wheel nuts in the
proper sequence to GM specifications.
Your rear drum brakes don’t have wear indicators, but
if
you ever hear a rear brake rubbing noise, have the rear
brake linings inspected immediately. Also, the rear
brake drums should be removed and inspected each time the tires are removed for rotation or changing. When
you have the front brake pads replaced, have the rear
brakes inspected, too.
Brake linings should always be replaced as complete axle sets.
See “Brake System Inspection” in Section
7 of this
manual under Part
C “Periodic Maintenance
Inspections.”
