Inflation -- Tire Pressure
The Tire-Loading Information label, located on
the inside of the trunk lid, 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
1 mile (1.6 km).
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 the following:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
NOTICE: (Continued) NOTICE: (Continued)
If your tires have too much
air (overinflation),
you can get the following:
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 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell
if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put
the valve caps back on the valve stems.
They help prevent leaks by keeping out
dirt and moisture.

Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your retailer or other service
outlets. Larger areas of finish damage can be corrected
in your retailer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect
on the underbody. If these are
not removed, accelerated corrosion (rust) can occur
on the underbody parts such as fuel lines, frame,
floor pan and exhaust system even though they have
corrosion protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect. Dirt packed in ,closed areas
of the frame should be loosened before being flushed.
Your retailer or an underbody car washing system can
do this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on your vehicle. This damage
can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched into
the paint surface.
Although no defect in the paint job causes this,
Oldsmobile will repair, at no charge to the owner,
the surfaces of new vehicles damaged by this fallout
condition within 12 months or 12,000 miles (20
000 km)
of purchase, whichever occurs first.

How This Section is Organized
The remainder of this section is divided into five parts:
“Part
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 retailer’s service department or another
qualified service center do these jobs.
Performing maintenance work on
a vehicle can
be dangerous. In trying to do some jobs, you can
be seriously injured.
Do your own maintenance
work only if ;you have the required know-how
and the proper tools and equipment for the job.
If you have any doubt, have
a qualified
technician do the work.
If you are skilled enough
to do some work on your
vehicle, you will probably want
to get the service
information
GM publishes. See “Service and Owner
Publications” in the Index.
“Part 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.
“Part C
: Periodic Maintenance Inspections” explains
important inspections that your Oldsmobile retailer’s service department or another qualified service center
should perform.
“Part
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.
“Part
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 part. 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.

Part A: Scheduled Maintenance
Services
Using Your Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we don’t know
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 making 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’ll find
in the schedules in this section.
So please read this
section and note how you drive. If you have any
questions on how to keep your vehicle
in good
condition, see your Oldsmobile retailer.
This part tells you the maintenance services you should
have done and when you should schedule them. If you
go to your retailer for your service needs, you’ll know
that GM-trained and supported service people will
perform the work using genuine GM parts. The proper fluids and lubricants to use are listed in
Part D.
Make sure whoever services your vehicle uses these. All
parts should be replaced and all necessary repairs done
before you or anyone else dnves the vehicle.
These schedules are for vehicles that:
0 carry passengers and.cargo within recommended
limits. You will find these limits on your vehicle’s
Tire-Loading Information label. See “Loading Your
Vehicle’’ in the Index.
0 are driven on reasonable road surfaces within legal-
0 use the recommended fuel. See “Fuel” in the Index.
driving limits.
Selecting the Right Schedule
First you’ll
need to decide which of the two schedules is
right for your vehicle. Here’s how to decide which
schedule to follow:
7-3

.Maintenance Schedule
I Short Trip/City Definition I
Follow the Short TripKity Maintenance Schedule if any
one of these conditions is true for your vehicle:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
driving in stop-and-go traffic).
Most trips include extensive idling (such as frequent
0 Most trips are through dusty areas.
0 You frequently tow a trailer or use a carrier on top of
your vehicle.
If the vehicle is used for delivery .service, police, taxi
or other commercial application.
One of the reasons you should follow this schedule ifyou
operate your vehicle under any
of these conditions is that
these conditions cause engine oil to break down soonez
