Tire Inspection and Rotation
To make your tires last longer, have
them inspected and rotated at the
mileages recommended in the
Maintenance Schedule. See the
Index
under Scheduled Maintenance
Services.
Use this rotation pattern. After
the tires have been rotated, adjust
the front and rear inflation pressure as
shown on the Tire-Loading Information
label. Make certain that all wheel nuts
are properly tightened. See the
Index
under Wheel Nut Torque.
A
Rust or dirt on a wheel, or on
the parts to which it is
fastened, can make the wheel nuts
become loose after a time. The
wheel could come
off and cause an
accident. When you change a
wheel, remove any rust or dirt from
places where the wheel attaches to
the vehicle. In an emergency, you
can use a cloth or a paper towel to
do this; but be sure to use a scraper
or wire brush later, if you need to,
to get all the rust or dirt
off. (See
the
Index under Changing a Flat
Tire. 1

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.
A
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. I
If you are skilled 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 the
Index under Service
Publications.
Section B: Owner Checks & 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 inspections that your Oldsmobile dealer’s service
department or another qualified service center should
perform.
Section
D: Recommended Fluids & 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 qual@ your vehicle for warranty repairs.

people will perform the work using genuine GM parts.
