In¯ation - Tire Pressure
The Tire-Loading Information label, which is on the
driver's door lock pillar, shows the correct in¯ation
pressures for your tires when they're cold. ªColdº means
your vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
Notice:Don't let anyone tell you that underin¯ation
or overin¯ation is all right. It's not. If your tires
don't have enough air (underin¯ation), you can get
the following:
·Too much ¯exing
·Too much heat
·Tire overloading
·Bad wear
·Bad handling
·Bad fuel economy
If your tires have too much air (overin¯ation),
you can get the following:
·Unusual wear
·Bad handling
·Rough ride
·Needless damage from road hazards
When to Check
Check your tires once a month or more.
Also, check the tire pressure of the spare tire.
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can't tell if your tires are properly in¯ated
simply by looking at them. Radial tires may look
properly in¯ated even when they're underin¯ated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and moisture.
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires as
soon as possible and check wheel alignment. Also check
for damaged tires or wheels. See
When It Is Time for
New Tires on page 5-62andWheel Replacement on
page 5-64for 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. See ªPart A: Scheduled
Maintenance Services,º in Section 6, for scheduled
rotation intervals.

Uniform Tire Quality Grading
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance.
(This applies only to vehicles sold in the United States.)
The grades are molded on the sidewalls of most
passenger car tires. The Uniform Tire Quality Grading
system does not apply to deep tread, winter-type
snow tires, space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12 inches
(25 to 30 cm), or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a speci®ed government test course.
For example, a tire graded 150 would wear one and
a half (1.5) times as well on the government course as
a tire graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart signi®cantly from the norm
due to variations in driving habits, service practices
and differences in road characteristics and climate.
Traction ± AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire's ability
to stop on wet pavement as measured under controlled
conditions on speci®ed government test surfaces of
asphalt and concrete. A tire marked C may have poor
traction performance. Warning: The traction grade
assigned to this tire is based on straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.

Vehicle Identi®cation
Vehicle Identi®cation Number (VIN)
This is the legal identi®er for your vehicle. It appears on
a plate in the front corner of the instrument panel, on
the driver's side. You can see it if you look through the
windshield from outside your vehicle. The VIN also
appears on the Vehicle Certi®cation and Service Parts
labels and the certi®cates of title and registration.
Engine Identi®cation
The 8th character in your VIN is the engine code. This
code will help you identify your engine, speci®cations
and replacement parts.
Service Parts Identi®cation Label
You'll ®nd this label inside the glove box on the door.
It's very helpful if you ever need to order parts.
On this label is:
·your VIN,
·the model designation,
·paint information and
·a list of all production options and special
equipment.
Be sure that this label is not removed from the vehicle.

How This Section is Organized
This maintenance schedule is divided into ®ve parts:
ªPart A: Scheduled Maintenance Servicesºexplains
what to have done and how often. Some of these
services can be complex, so unless you are technically
quali®ed 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 quali®ed technician do the work.
If you want to get the service information, see
Service
Publications Ordering Information on page 7-11.ªPart B: Owner Checks and Servicesºtells you what
should be checked and when. It also explains what
you can easily do to help keep your vehicle in good
condition.
ªPart C: Periodic MaintenanceInspectionsºexplains
important inspections that your dealer's service
department can perform for you.
ªPart D: Recommended Fluids and Lubricantsºlists
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.
ªPart E: Maintenance Recordºis 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 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.
These schedules are 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 4-51.
·are driven on reasonable road surfaces within legal
driving limits.
·are driven off-road in the recommended manner.
See
Off-Road Driving with Your Four-Wheel-Drive
Vehicle on page 4-16.
·use the recommended fuel. SeeGasoline Octane
on page 5-4
.
6-4

Selecting the Right Schedule
First you'll need to decide which of the two schedules is
right for your vehicle. Here's how to decide which
schedule to follow:
Short Trip/City De®nition
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 ®rst).
Every 6,000 Miles (10 000 km):Passenger
Compartment Air Filter Inspection (If Equipped).
Tire Rotation.
Every 15,000 Miles (25 000 km):Engine Air Cleaner
Filter Inspection. Automatic Transmission Service
(severe conditions only). Manual Transmission Fluid
Change. Transfer Case Fluid Change. Differential Fluid
Change. Propeller Shafts and U-Joints Inspection
(or every 15 months, whichever occurs ®rst).
Every 30,000 Miles (50 000 km):Engine Air Cleaner
Filter Replacement. Air Filter Replacement (If Equipped).
Ignition Coil Plug Cap Inspection (or every 30 months,
whichever occurs ®rst). Engine Accessory Drive Belt
Inspection (or every 30 months, whichever occurs ®rst).
Cooling System Service (or every 30 months, whichever
occurs ®rst). Fuel Tank, Cap, and Lines Inspection.
Fuel Filter Replacement (or every 30 months, whichever
occurs ®rst).
6-5

Every 45,000 Miles (75 000 km):Automatic
Transmission Fluid Hose Inspection (or every
45 months, whichever occurs ®rst).
Every 60,000 Miles (100 000 km):Fuel Tank Cap
Gasket Replacement. Emission System Hoses
Inspection. Brake Fluid Service. Spark Plug
Replacement.
Every 100,000 Miles (166 000 km):Automatic
Transmission Service (normal conditions).

Emissions Canister and Air Suction Filter Replacement
(or every 120 months, whichever occurs ®rst). Engine
Accessory Drive Belt Replacement (or every
120 months, whichever occurs ®rst).
These intervals only summarize maintenance services.
Be sure to follow the complete scheduled maintenance
on the following pages.
Long Trip/Highway De®nition
Follow this scheduled maintenanceonlyif 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 7.5 months, whichever occurs ®rst).
Tire Rotation.
Every 15,000 Miles (25 000 km):Engine Air Cleaner
Filter Inspection. Automatic Transmission Service
(severe conditions only). Passenger Compartment
Air Filter Inspection (If Equipped). Propeller Shafts and
U-Joints Inspection (or every 15 months, whichever
occurs ®rst).
6-6

Every 30,000 Miles (50 000 km):Engine Accessory
Drive Belt Inspection (or every 30 months, whichever
occurs ®rst). Cooling System Service (or every
30 months, whichever occurs ®rst). Fuel Tank, Cap and
Lines Inspection. Engine Air Cleaner Filter Replacement.
Passenger Compartment Air Filter Replacement
(If Equipped). Ignition Coil Plug Cap Inspection (or every
30 months, whichever occurs ®rst). Manual Transmission
Fluid Change. Transfer Case Fluid Change. Differential
Fluid Change. Fuel Filter Replacement (or every
30 months, whichever occurs ®rst).
Every 45,000 Miles (75 000 km):Automatic
Transmission Fluid Hose Inspection (or every
45 months, whichever occurs ®rst).
Every 60,000 Miles (100 000 km):Fuel Tank Cap
Gasket Replacement. Emission System Hoses
Inspection. Spark Plug Replacement. Brake Fluid
Service.
Every 100,000 Miles (166 000 km):Automatic
Transmission Service (normal conditions).
Every 120,000 Miles (200 000 km):Evaporative
Emissions Canister and Air Suction Filter Replacement
(or every 120 months, whichever occurs ®rst).
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 service shown at 120,000 miles
(200 000 km) should be repeated at the same interval
after 120,000 miles (200 000 km) for the life of this
vehicle.

Part B: Owner Checks and Services on page 6-24andPart C: Periodic MaintenanceInspections on
page 6-28.
Footnotes
²The 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.
+A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-29.
