Parking on Hills
You really should not park your vehicle,
with a trailer attached, on a hill. If
something goes wrong, your rig could
start to move. People can be injured,
and both your vehicle and the trailer
can be damaged.
But
if you ever have to park your rig on
a hill, here’s how to do it:
1. Apply your regular brakes, but don’t
shift into
P (Park) yet.
2. Have someone place choclts under
the trailer wheels.
3. When the wheel chocks are in place,
release the regular brakes until the
chocks absorb the load.
apply your parking brake, and then
shift to
P (Park).
4. Reapply the regular brakes. Then
5. Release the regular brakes.
When You Are Ready to Leave
Affer Parking on a Hill
1. Apply your regular brakes and hold
the pedal down while
you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear
4. Stop and have someone pick up and

store the chocks.
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, belts, cooling
system, and brake adjustment. Each of
these is covered in this manual, and the
Index will help you find them quicltly. 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.

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 dealer, a service
station or a local recycling center for
help.
Air Cleaner
Refer to the Maintenance Schedule to
determine when to replace the air filter.
See
Scheduled Maintenance Services in
the Index.
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
When to Check and Change
A good time to check your automatic
transaxle fluid level is when the engine
oil is changed. Refer
to the Maintenance
Schedule to determine when to change
your fluid. See
Scheduled Maintenance
Services
in the Index.
How to Check
Because this operation can be a little
difficult, you may choose to have this
done at an Oldsmobile dealership
Service Department.
If you do it yourself, be sure to follow
all the instructions here, or you could
get a false reading on the dipstick.
NOTICE:
Too much or too little fluid can
damage your transaxle.
Too much
can mean that some of the fluid
could come out and fall on hot
engine parts or exhaust system,
starting a fire. Be sure to get an
accurate reading if you check your
transaxle fluid.
Wait at least
30 minutes before
checking the transaxle fluid level
if you
have been driving:

How to Add Fluid
Refer to the Maintenance Schedule to
determine what kind of transaxle fluid
to use. See
Recommended Fluids and
Lubricants
in the Index.
If the fluid level is low, add only enough
of the proper fluid to bring the level into
the cross-hatched area
on the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel: add
enough fluid at the dipstick hole to
bring it to the proper level.
It doesn’t take much fluid, generally less
than a pint
(OSL). Don’t overfill. We
recommend you use only fluid labeled
DEXRONo-I11 or DEXRON@-IIE,
because fluids with that label are made
especially for your automatic transaxle.
Damage caused by fluid other than
DEXRONo-I11 or DEXRONB-IIE is not
covered by your new vehicle warranty.
After adding fluid, recheck the fluid
level as described under
How to
Check.

Inflation-Tire Pressure
The CertificatiodTire label which is on
the rear edge of the driver’s door shows
the correct inflation pressures for your
tires, when they’re cold. “Cold” means
your vehicle has been sitting for at least
three hours or driven no more than a mile.
NOTICE:
Don’t let anyone tell you that
underinflation
or overinflation is all
right. It’s not. If your tires don’t
have enough air (underinflation)
you can get:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air
(overinflation) you can get:
Unusual wear
Bad handling
Rough ride
Needless damage from road
hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It
should be at
60 psi (420 1tPa).
How to Check
Use a good quality pocket-type gage to
check tire pressure. Simply loolting at
the tires will not tell you the pressure,
especially
if you have radial tires -
which may look properly inflated even if
they’re underinflated.
If your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt and moisture.

Tire Inspection and Rotation
To make your tires last longer, have
them inspected and rotated at the
mileages recommended in the
Maintenance Schedule. See
Scheduled
Maintenance Services
in the Index.
Use this rotation pattern.
After the tires have been rotated, adjust
the front and rear inflation pressure as
shown on the CertificationlTire label.
Make certain that all wheel nuts are
properly tightened. See
Wheel Nut

Introduction
A Word About Maintenance
We at General Motors want to help you
keep your vehicle in good working
condition. But we don’t lmow exactly
how you’ll drive it. You may drive very
short distances only a few times a week.
Or you may drive long distances all the
time in very hot, dusty weather.
You
may use your vehicle in malting
deliveries. Or
you may drive it to work,
to do errands or in many other ways.
Because of all the different ways people
use their GM vehicles, maintenance
needs vary.
You may even need more
frequent checks and replacements than
you will find in the schedules in this
part.
So please read this part and note
how you drive. If you have any
questions on how to keep your vehicle
in good condition, see your Oldsmobile
dealer, the place many GM owners
choose to have their maintenance work
done. Your dealer can be relied upon to
use proper parts and practices.
Your Vehicle and the Environment
Proper vehicle maintenance not only
helps to keep your vehicle in good
working condition, but also helps the
environment. All recommended
maintenance procedures are important. Improper vehicle maintenance or the
removal of important components can
significantly affect the quality
of the air
we breathe. Improper fluid levels or
even the wrong tire inflation can
increase the level of emissions from
your vehicle.
To help protect our
environment, and to help keep your
vehicle in good condition, please
maintain your vehicle properly.
How This Part is Organized
The remainder of this part is divided
into five sections:
Section
A: Scheduled Maintenance
Services shows what to have done and
how often. Some of these services can
be complex,
so unless you are technically
qualified and have the necessary
equipment, you should let your dealer’s
service department or another qualified
service center do these jobs. If
you are skulled enough to do some
work on your vehicle, you will probably
want to get the service information GM
publishes. You will find a list of
publications and how to get them in
this manual. See
Service Publications
in the Index.
Section B: Owner Checks and Services
tells you what should be checked
whenever you stop for fuel. It also
explains what you can easily do to help
keep your vehicle in good condition.
Section
C: Periodic Maintenance
Inspections explains important
ProCarManuals.com

inspections that your Oldsmobile
dealer’s service department or another
qualified service center should perform.
Section
D: Recommended Fluids and
Lubricants lists some products
GM
recommends to help keep your vehicle
properly maintained. These products, or
their equivalents, should be used
whether you do the work yourself or
have
it done.
Section
E: Maintenance Record
provides
a place for you to record the
maintenance performed on your vehicle.
Whenever any maintenance is
performed, be sure to write
it down in
this section. This will help you
determine when your next maintenance
should be done. In addition, it is
a good
idea to keep your maintenance receipts.
They may be needed to qualify your
vehicle for warranty repairs.
Section A: Scheduled
Maintenance Services
Using Your Maintenance
Schedule
This section tells you the maintenance
services you should have done and
when you should schedule them. Your
Oldsmobile dealer knows your vehicle
best and wants you to be happy with it.
If
you go to your dealer for your service
needs, you’ll know that GM-trained and
supported service people will perform
the work using genuine
GM parts.
These schedules are for vehicles that:
carry passengers and cargo within
recommended limits.
You will find
these limits on your vehicle’s
CertificatiodTire label. See
Loading
Your Vehicle in the Index.
are driven on reasonable road
surfaces within legal driving limits.
