Index
Here’s an alphabetical listing of almost every subject in this manual. You can use it to quickly find
something you want to read.

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 Achieva 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 wires wrapped with yellow tape
or 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.

Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system and brake adjustment.
Each
of these is covered in this manual, and the Index
will help you find them quickly. If you’re trailering, it’s
a good idea to review these sections before you
start
your trip.
Check periodically to
see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating’’
in the Index.
Towing A Trailer
(Except 3100 Engine)
Your vehicle is neither designed nor intended to tow
a trailer.

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. “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 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 (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.
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 1 OW-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 20W-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 triplcity
maintenance schedule:
e

Most trips are less than 5 to 10 miles (8 to 16 km).
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 commercial 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.
