2003 PONTIAC GRAND PRIX maintenance

Aluminum or Chrome Plated 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.
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.

Protection
Have you purchased the GM Protection Plan?
The Plan supplements your new vehicle warranties.
See your Warranty and Owner Assistance booklet
or your dealer for details.
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 can
even affect the quality of the air we breathe. Improper
fluid levels or the wrong tire inflation can increase
the level of emissions from your vehicle.
To help protect
our environment, and to keep your vehicle in good
condition, please maintain your vehicle properly.
Maintenance Requirements
Maintenance intervals, checks, inspections and
recommended fluids and lubricants as prescribed in
this manual are necessary to keep your vehicle in good
working condition. Any damage caused by failure to
follow recommended maintenance may not be covered
by warranty.
6-2

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.
Perl_______ lg maintenance work on a vehic.- 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 want to get the service information, see Service
Publications Ordering Information on page
7- 10.
“Part B: Owner Checks and Services” tells you what
should be checked and when. It also explains what
you can easiiy
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.
6-3

Part A: Scheduled Maintenance
Services
This part contains engine oil scheduled maintenance
which explains the engine oil life system and how
it indicates when to change the engine oil and filter.
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 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 the different ways people use their vehicles,
maintenance needs may vary. You may need more
frequent checks and replacements.
So please read the
following and note how you drive.
If you have
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 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 drives the
vehicle.
This schedule is for vehicles that:
carry passengers and cargo within recommended
limits. You will find these on your vehicle’s
Tire-Loading Information label. See Loading
Your
Vehicle on page 4-35.
are driven on reasonable road surfaces within legal
use the recommended fuel. See Gasoline Octane
driving limits.
on page 5-5.
6-4

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 B: Owner Checks and Services on page
6-9
and Part C: Periodic Maintenance Inspections on
page
6- 13.
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
6-14,
Engine Oil 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 OIL SOON light 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 5-18 for information on resetting the system.
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.
