2003 PONTIAC BONNEVILLE engine

Long Trip/Highway Definition
Follow this scheduled maintenance only if none of the
conditions from the Short Trip/City Scheduled
Maintenance are true.
Do not use this schedule if the
vehicle
is used for trailer towing, driven in a dusty area
or used
off paved roads. Use the Short Trip/City
schedule for these conditions
Driving a vehicle with a fully warmed engine under
highway conditions will cause engine oil to break down
slower.
Long Trip/Highway Intervals
Every 7,500 Miles (12 500 km): Engine Oil and Filter
Change (or every 12 months, whichever occurs
first). Tire Rotation.
Every 30,000 Miles (50 000 km): Supercharger Oil
Check (or every 36 months, whichever occurs first)
(3800 Code 1 V6 engine only). Engine Air Cleaner Filter
Replacement.
Every 50,000 Miles (83 000 km): Automatic Transaxle
Service (severe conditions only).
Every 100,000 Miles (166 000 km): Spark Plug Wire
Inspection. Spark Plug Replacement. Automatic
Transaxle Service (normal conditions).
Every 150,000 Miles (240 000 km): Cooling System
Service (or every 60 months, whichever occurs
first). Engine Accessory Drive Belt Inspection.
These intervals only summarize maintenance services.
Be sure to follow the complete scheduled maintenance
on the following pages.
Short Trip/City Scheduled
Maintenance
The services shown in this schedule up to 100,000 miles
(1 66
000 km) should be repeated after 100,000 miles
(166
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.

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.
*If your vehicle has the GM Oil Life SystemTM,
a
computer system lets you know when to change the 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 oii 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. An ENGINE
OIL CHANGE SOON 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.
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
5-15 for information on resetting the system.
@ Whenever the tires are rotated, the Check Tire
Pressure §ystem must be reset.
+A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-23.
