Accessory Inflator
Your vehicle may have an air inflator. With it, you can
inflate things like air mattresses and basketballs,
and you can also use it to bring your tires up to the
proper pressure.
The air inflator is located in the rear compartment on
the driver’s side. To remove the cover, pull the tab
on the cover and pull it
off.
This is the switch for
the air inflator.
There may be an air inflator kit stored in the glove box.
It includes a 20-foot
(6 m) hose with an air pressure
gage and nozzle adapters.
....___ ting something too much can make it
explode, and you or others could be injured.
Be sure to read the inflator instructions, and
inflate any object only
to its recommended
pressure.
To use your air inflator system, do the following:
1. Turn the ignition to ACCESSORY or RUN.
2. Attach the appropriate nozzle adapter, if required,
to the end
of the hose that has the pressure gage.
3. Attach that end of the hose to the object you wish
to inflate.
4. Remove the protective cap covering the outlet.
5. Attach the other end of the hose to the outlet.
6. Press the accessory inflator switch. The light in the
switch will come on to show the system is working.
If the air inflator system does not turn on or the
light does not come on, the fuse may be blown or
installed incorrectly. See
Fuses and Circuit Breakers on
page 5-96 or see your dealer for service.

Aluminum Wheels
Keep your wheels clean using a soft clean cloth
with mild soap and water. Rinse with clean water.
After rinsing thoroughly, dry with a soft clean towel.
A wax may then be applied.
The surface of these wheels is similar to the painted
surface of your vehicle. Don’t use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,
cleaners with acid, or abrasive cleaning brushes on
them because you could damage the surface.
Do not
use chrome polish on aluminum wheels.
Don’t take your vehicle through an automatic car wash
that has silicone carbide tire cleaning brushes. These
brushes can also damage the surface of these wheels
Tires
To clean your tires, use a stiff brush with tire cleaner.
Notice: When applying a tire dressing, always take
care to wipe
off any overspray or splash from all
painted surfaces on the body or wheels of the
vehicle. Petroleum-based products may damage the
paint finish and tires.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to parts repaired or
replaced to restore corrosion protection.
Original manufacturer replacement parts will provide the
corrosion protection while maintaining the warranty.
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 major repair
expense.
Minor chips and scratches can be repaired with touch-up
materials avaliable from your dealer or other service
outlets. Larger areas
of finish damage can be corrected
in your dealer’s body and paint shop.

How This Section is Organized
This maintenance schedule is divided into five parts:
“Part
A: Scheduled Maintenance Services” explains
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.
F ming main1 ance Irk on a ~ hide
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. “Part
B: Owner Checks and Services”
tells you what
should be checked and when. 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 dealer’s service
department or another qualified service center
should perform.
“Part
D: Recommended Fluids and Lubricants” lists
some recommended products necessary 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” is a place for you to
record and keep track of the maintenance performed
on your vehicle. Keep your maintenance receipts.
They may be needed to qualify your vehicle for
warranty repairs.

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 to keep your
vehicle in good working condition. But we don’t know
exactly how you’ll drive it. You may drive 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
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 GM parts.
The proper fluids and lubricants to use are listed in
Part
D. Make sure whoever services your vehicle uses
them.
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
Certificationflire label. See
Loading Your Vehicle
on page 4-34.

Scheduled Maintenance
The services shown in this schedule up to 100,000 miles
(1 66 000 km) should be repeated after 100,000 miles
(1 66 000 km) at the same intervals for the life of
this vehicle. The services shown at
150,000 miles
(240 000 km) should be repeated at the same interval
after
150,000 miles (240 000 km) for the life of this
vehicle.
See
Part 5: Owner Checks and Services on page 6-10
and Part C: Periodic Maintenance Inspections on
page
6- 14.
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
mainienance
be recoraea.
+ 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 System (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, if 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.
6-5

If the system is ever reset accidentally, you must
change your oil at
3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed. See
Engine Oil on
page
5-74 for information on resetting the system.
An Emission Control Service.
Lubricate chassis components with each engine oil
and filter change.
Lubricate the suspension, steering linkage, transaxle
shift linkage and the underbody contact points and
linkage.
After the services are performed, record the date,
odometer reading and who performed the service on the
maintenance record pages in Part
E of this schedule.
