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. SeeLoading Your Vehicle
on page 4-29.
•are driven on reasonable road surfaces within legal
driving limits.
•use the recommended fuel. SeeGasoline 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 Denition
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.
•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. Passenger Compartment Air Filter
Replacement. Drive Belts Inspection.
Every 30,000 Miles (50 000 km):Engine Air Cleaner
Filter Replacement. Fuel Filter Replacement. Cooling
System Service. EVAP System Service. PCV System
Service. Brake Fluid Change (or 24 months, whichever
occurs first).
Every 50,000 Miles (83 000 km):Automatic Transaxle
Service (severe conditions only).
Every 60,000 Miles (100 000 km):EVAP System
Solenoid Valve Filter Replacement.
Every 100,000 Miles (166 000 km):Spark Plug
Replacement.
These intervals only summarize maintenance services.
Be sure to follow the complete scheduled maintenance
on the following pages.
6-5

Long Trip/Highway Denition
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 12 months, whichever occurs
first). Tire Rotation.
Every 15,000 Miles (25 000 km):Engine Air Cleaner
Filter Inspection. Passenger Compartment Air Filter
Replacement. Drive Belts Inspection.Every 30,000 Miles (50 000 km):Engine Air Cleaner
Filter Replacement. Fuel Filter Replacement. Cooling
System Service. EVAP System Service. PCV System
Service. Brake Fluid Change (or 24 months, whichever
occurs first).
Every 50,000 Miles (83 000 km):Automatic Transaxle
Service (severe conditions only).
Every 60,000 Miles (100 000 km):EVAP System
Solenoid Valve Filter Replacement.
Every 100,000 Miles (166 000 km):Spark Plug
Replacement.
These intervals only summarize maintenance services.
Be sure to follow the complete scheduled maintenance
on the following pages.
