Removing the Rear Seat Cushion

Notice: If you touch the exposed wires with the
metal on the seat cushion, you could cause a
short that could damage the battery and or wires.
Avoid contact between the rear seat and the
fuse center whenever you remove or reinstall the
rear seat. Do not remove covers from any of
the covered parts, and do not store anything under
the seats.

To remove the rear seat cushion, do the following:

1. Pull up on the front of the cushion to release the

front hooks.

2. Pull the cushion up and out toward the front of the

vehicle.

To reinstall the rear seat cushion, do the following:

{

CAUTION:

A safety belt that is not properly routed
through the seat cushion or is twisted will not
provide the protection needed in a crash. If the
safety belt has not been routed through the
seat cushion at all, it will not be there to work
for the next passenger. The person sitting in
that position could be badly injured. After
reinstalling the seat cushion, always check to
be sure that the safety belts are properly
routed and are not twisted.

Maintenance Schedule

Introduction

Important: Keep engine oil at the proper level and
change as recommended.

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.

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 scheduled maintenance may not be covered
by warranty.

Your Vehicle and the Environment

Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. 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, be sure to maintain your vehicle properly.

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 GM dealer’s service department do
these jobs.

Your GM dealer has GM-trained and supported
service people that will perform the work using genuine
GM parts.

{

CAUTION:

Performing maintenance work on a vehicle 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 purchase service information, see Service
Publications Ordering Information on page 7-11.

“Part B: Owner Checks and Services” tells you what
should be checked and when. It also explains what
you can easily do to help keep your vehicle in good
condition.

“Part C: Periodic Maintenance Inspections” explains
important inspections that your dealer’s service
department can perform for you.

“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

In this part 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 do not know exactly how
you will 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
will 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.

These schedules are for vehicles that:

•

carry passengers and cargo within recommended
limits. You will find these on the tire and loading
information label. See Loading Your Vehicle
on page 4-29.

•

are driven on reasonable road surfaces within legal
driving limits.

•

use the recommended fuel. See Gasoline Octane
on page 5-5.

6-4

-------------------------------------------------------------------------------------------------------------------------------------------------------------

Selecting the Right Schedule

First you will need to decide which of the two schedules
is right for your vehicle. Here is how to decide which
schedule to follow:

Short Trip/City Definition

Follow the Short Trip/City Scheduled Maintenance if any
one of these conditions is true for your vehicle:

•

Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures
are below freezing.

•

Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).

•

You frequently tow a trailer or use a carrier on top
of your vehicle.

•

If the vehicle is used for delivery service, police,
taxi or other commercial application.

One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooner.

Short Trip/City Intervals

Every 3,000 Miles (5 000 km): Engine Oil and Filter
Change (or 3 months, whichever occurs first).

Every 6,000 Miles (10 000 km): Tire Rotation.

Every 15,000 Miles (25 000 km): Engine Air Cleaner
Filter Inspection.

Every 30,000 Miles (50 000 km): Throttle Body Bore
and Valve Plates Inspection (V8 engine only).

Every 45,000 Miles (75 000 km): 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 (V6 engine only). 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.

6-5

-------------------------------------------------------------------------------------------------------------------------------------------------------------

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 15,000 Miles (25 000 km): Engine Air Cleaner
Filter Inspection.

Every 30,000 Miles (50 000 km): Throttle Body Bore
and Valve Plates Inspection (V8 engine only).

Every 45,000 Miles (75 000 km): 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 (V6 engine only). 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
(166 000 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.

See Part B: Owner Checks and Services on page 6-19
and Part C: Periodic Maintenance Inspections on
page 6-23.

Footnotes

† 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 System, 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 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. 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. See Engine
Oil on page 5-16. 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 Life System
on page 5-20 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 6-24.
