2007 PONTIAC GRAND PRIX maintenance reset

When the indicator nears empty, there is still a
little fuel left, but you should get more soon.
Here are four things owners usually ask about the
fuel gage. All these situations are normal and
do not indicate a problem with the fuel gage:
At the gas station the pump shuts off before
the gage reads full.
It takes more or less fuel to ll up than the
gage indicates. For example, the gage
reads half full, but it took more or less than
half the tank’s capacity to ll it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate full when the
ignition is turned off.
Driver Information Center (DIC)
The Driver Information Center (DIC) gives
important safety and maintenance facts. When the
vehicle’s ignition is turned on, all of the DIC
lights illuminate for a few seconds and an
introductory message will appear. After this, the
DIC will begin working.
DIC Controls and Displays

Tire Inspection and Rotation
Tire rotation is not recommended if your vehicle is
a GXP model equipped with P255/45R18 size
tires on the front wheels and P225/50R18 size tires
on the rear wheels. Different tire sizes front to
rear should not be rotated.
Tire rotation is recommended if the original
equipment tires installed on your vehicle are
of the same size and type on all four tire/wheel
positions. Original equipment tires of the
same size and type should be rotated every
5,000 to 8,000 miles (8 000 to 13 000 km).
Any time you notice unusual wear, rotate your
vehicle’s tires as soon as possible and check the
wheel alignment. Also check for damaged tires
or wheels. SeeWhen It Is Time for New Tires on
page 415andWheel Replacement on page 419
for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance on page 473for scheduled rotation
intervals.The correct rotation pattern shown here is only for
non-GXP tires.
Do not include the compact spare tire, if equipped,
in your vehicle’s tire rotation.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the Tire
and Loading Information label, and reset the Tire
Pressure Monitor System. SeeTire Pressure
Monitor System on page 409for additional
information.

The proper replacement parts, uids, and
lubricants to use are listed inRecommended
Fluids and Lubricants on page 483andNormal
Maintenance Replacement Parts on page 484.
When your vehicle is serviced, make sure these
are used. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of
genuine GM parts.Scheduled Maintenance
When the CHANGE OIL SOON message comes
on, it means that service is required for your
vehicle. SeeDIC Warnings and Messages on
page 200. Have your vehicle serviced as soon as
possible within the next 600 miles (1 000 km). It is
possible that, if you are driving under the best
conditions, the engine oil life system may not
indicate that vehicle service 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 GM Goodwrench
®
dealer has GM-trained service technicians who will
perform this work using genuine GM parts and reset
the system.

If the engine oil life system is ever reset
accidentally, you must service your vehicle within
3,000 miles (5 000 km) since your last service.
Remember to reset the oil life system whenever
the oil is changed. SeeEngine Oil Life System on
page 353for information on the Engine Oil Life
System and resetting the system.
When the CHANGE OIL SOON message appears,
certain services, checks, and inspections are
required. Required services are described in the
following for “MaintenanceI” and “MaintenanceII.”
Generally, it is recommended that your rst
service be MaintenanceI, your second service be
MaintenanceII, and that you alternate
MaintenanceIand MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay be
required more often.MaintenanceI— Use MaintenanceIif the
CHANGE OIL SOON message comes on within
10 months since the vehicle was purchased
or MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the
previous service performed was MaintenanceI.
Always use MaintenanceIIwhenever the message
comes on 10 months or more since the last
service or if the message has not come on at all
for one year.
