Long Trip/Highway Scheduled
Maintenance
The services shown in this schedule up to 100,000 miles
(166
000 km) should be repeated after 100,000 miles
(1 66 800 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 6-18
and Part C: Periodic Maintenance Inspections on
page 6-22.
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,
urqe 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
engine oil and filter. This is based on engine revolutions
aiid eiigifie telvpei-atdre, and ncf c:: ml?eage. 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 wil! 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
5-75 for information on resetting the system.
@ Whenever the tires are rotated, the Check Tire
Pressure System must be reset.
+ A good time to check your brakes is during tire
rotation. See Brake System Inspection on page
6-23.

Part B: Owner Checks and Services
Listed in this part are owner checks and services
which should be perFormed at the intervals specified to
help ensure the safety, dependability and emission
control performance of your vehicle.
Be sure any necessary repairs are completed at once.
Whenever any fluids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
in Part D.
At Each Fuel Fill
It is important for you or a service station attendant to
perform these underhood checks at each fuel fill.
Engine Oil Level Check
Check the engine oil level and add the proper oil if
necessary. See Engine Oil on page 5-75 for further
details.
Engine Coolant Level Check
Check the engine coolant level and add DEX-COOL@
coolant mixture
if necessary. See Engine Coolant
on page 5-26
for further details.
Windshield Washer Fluid Level Check
Check the windshield washer fluid level in the windshield
washer tank and add the proper fluid
if necessary.
See
Windshield Washer Fluid on page 5-40 for further
details.
At Least Once a Month
Tire Inflation Check
Make sure tries are inflated to the correct pressures.
Don’t forget to check your spare tire. See
Tires on
page 5-62
for further details.
Cassette Tape Player Service
Clean cassette tape player. Cleaning should be done
every
50 hours of tape play. See Audio System(s)
on page
3-77 for further details.
6-1 8

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag
system does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged or that
streak or miss areas of the windshield.
Also see
“Windshield Wiper and Wiper Blades” under Cleaning
the Outside
of Your Vehicle on page 5-85.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth, During very cold,
damp weather more frequent application may be
required. See
Part D: Recommended Fluids and
Lubricants on page
6-24.
Automatic Transaxle Check
Check the transaxle fluid level; add if needed. See
Automatic Transaxle Fluid on page 5-23. A fluid loss
may indicate a problem. Check the system and repair if
needed.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified in Part
D.
Lubricate all hinges and latches, including those for the
hood, rear compartment, glove box door, console
door and any folding seat hardware. Part D tells you
what to use. More frequent lubrication may be required
when exposed to a corrosive environment.

Parking Brake on page 2-31 if
necessary.
Do not use the accelerator pedal, and be ready to
turn
off the engine immediately if it starts.
Try to start the engine in each gear. The starter
should work only in PARK
(P) or NEUTRAL (N).
If the starter works in any other position, your
vehicle needs service.
