Rear Position
3. Make sure the jack head is positioned so that the
rear axle
is resting securely between the grooves
that are on the jack head. Turn the wheel
wrench clockwise to raise the vehicle. Raise the
vehicle far enough
off the ground so there is enough
room for the spare tire to
fit under the wheel well.
4. Remove all the wheel
nuts and take
off the
flat tire.
Rust or dirt on the 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
the 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.

Part A: Scheduled Maintenance
Services
This part contains engine oil and chassis lubrication scheduled maintenance which explains the engine oil life
system and how it indicates when to change the
engine oil and filter. Lubricate chassis components with
each oil change.
Also, listed are scheduled maintenance
services which are to be performed at the mileage
intervals specified.
Using Your Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good 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 in
very hot, dusty weather. You may use your vehicle in
making deliveries. Or yo may drive
it to work, to
do errands or in many other ways.
Because
of all the different ways people use their
vehicles, maintenance needs vary. You may need more
frequent checks and replacements.
So please read
the following and note how you drive.
If you have any
questions on how to keep your vehicle in good condition,
see your dealer. This part tells
you the maintenance services you should
have done and when you should schedule them.
When 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.
The proper fluids and lubricants
so 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 drives the
vehicle.
This schedule is for vehicles that:
carry passengers and cargo within recommended
limits. You will find these limits on your vehicle’s
Certification/Tire label. See
Loading Your Vehicle on
page 4-45.
are driven on reasonable road surfaces within legal
driving limits.

this vehicle. The services shown at
150,000 miles
(240
000 km) and 200,000 miles (332 000 km) should

Footnotes
t The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle
's useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
+ A good time to check your brakes is during tire
rotation. See Brake System Inspection on page
6-15.
Engine Oil and Chassis Lubrication
Scheduled Maintenance
Change engine oil and filter as indicated by the GM
Oil Life SystemTM (or every 12 months, whichever
occurs first). Reset the system.
Your vehicle has a computer system that lets you know
when to change the engine oil and filter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions,
the mileage at which an oil change will be indicated can
vary considerably. For the oil life system to work
properly, you must reset the system every time the oil is
changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change
is
necessary. A CHANGE ENGINE OIL message will
come on. Change your oil as soon as possible within
the next two times you stop for fuel. It is possible that,
it
you are driving under the best conditions, the oil life
system may not indicate that an
oil change is necessary
for over a year. However, your engine
oil and filter
must be changed at least once a year and at this time
the system must be reset. It
is also important to
check your oil regularly and keep
it at the proper level.
