2004 PONTIAC GRAND PRIX mileage

Speedometer and Odometer
The speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer, located on the Driver Information Center
(DIC) display, shows how far your vehicle has been
driven, in either miles or kilometers. See
DIC Controls
and Displays on page 3-45for more information.
If the vehicle has the Head-Up Display (HUD), the speed
will also be displayed on the HUD screen.
You may wonder what happens if a vehicle has to have
a new odometer installed. It the new one can be set
to the mileage total of the old odometer, than that will be
done. If it can't, than it will be set at zero and a label
must be put on the driver's door to show the old mileage
reading when the new odometer was installed.
Trip Odometer
The trip odometer, located in the Driver Information
Center (DIC), tells you how far you have driven since you
last reset it. You are able to see the miles (kilometers) for
two different trips. See
DIC Controls and Displays on
page 3-45for more information on setting the trip
odometer.
Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
Notice:Do not operate the engine with the
tachometer in the shaded warning area, or engine
damage may occur.

will accumulate mileage. For example, if you have
driven 5.0 miles (8.0 km) since you started the vehicle,
and then activate the reto-active reset feature, the
display will show 5.0 miles (8.0 km) since you started
your vehicle. As you drive, the display will then increase
to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.
If the retro-active reset feature is activated after the
vehicle is started, but before it begins moving, the
display will show the number of miles or kilometers
that were driven during the last ignition cycle.

We hope you'll want to keep your GM vehicle all GM.
Genuine GM parts have one of these marks:
Doing Your Own Service Work
If you want to do some of your own service work, you'll
want to use the proper service manual. It tells you
much more about how to service your vehicle than this
manual can. To order the proper service manual,
see
Service Publications Ordering Information on
page 7-10.
Your vehicle has an air bag system. Before attempting
to do your own service work, see
Servicing Your Air
Bag-Equipped Vehicle on page 1-56.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See
Part E: Maintenance Record on page 6-17.
{CAUTION:
You can be injured and your vehicle could be
damaged if you try to do service work on a
vehicle without knowing enough about it.
·Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.

When to Change Engine Oil
(GM Oil Life System)
Your vehicle has a computer system that lets you know
when to change the engine oil and ®lter. 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 ®lter must be
changed at least once a year and at this time the system
must be reset. Your dealer has GM-trained service
people who will perform this work using genuine GM
parts and reset the system. It is also important to check
your oil regularly and keep it at the proper level.
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.
How to Reset the GM Oil Life System
The GM Oil Life System calculates when to change
your engine oil and ®lter based on vehicle use.
Anytime your oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where you change your oil prior to a
CHANGE OIL SOON message appearing on the DIC,
reset the system.
To reset the GM Oil Life System, after the oil has been
changed, use the following procedure:
1. Press the options button on the DIC until ENGINE
OIL MONITOR appears on the DIC screen.
2. Press the set/reset button to reset the system.
The next screen indicates that the engine oil monitor
system has been reset.
If the vehicle is equipped with the trip computer DIC,
when the gage button is pressed and the OIL LIFE
REMAINING mode appears, it should read 100 percent
OIL LIFE REMAINING.

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 ®lter.
Also, listed are scheduled maintenance services which
are to be performed at the mileage intervals speci®ed.
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 to 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 ¯uids 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 ®nd 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
driving limits.
·use the recommended fuel. SeeGasoline Octane
