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 the vehicle warranties. See the Warranty
and Owner Assistance booklet or your dealer/retailer for
details.
Maintenance Requirements
Notice:Maintenance intervals, checks, inspections,
replacement parts, and recommended uids and
lubricants as prescribed in this manual are necessary
to keep this vehicle in good working condition.
Any damage caused by failure to follow scheduled
maintenance might not be covered by the vehicle
warranty.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep the
vehicle in good working condition, but also helps the
environment. All recommended maintenance is
important. Improper vehicle maintenance can even affect
the quality of the air we breathe. Improper uid levels or
the wrong tire ination can increase the level of emissions
from the vehicle. To help protect the environment, and to
keep the vehicle in good condition, be sure to maintain
the vehicle properly.
6-2

The proper replacement parts, uids, and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 6-14andMaintenance Replacement Parts
on page 6-16. When the vehicle is serviced, make sure
these are used. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of genuine
parts from your dealer/retailer.
Scheduled Maintenance
To maintain the ride, handling, and performance
of this vehicle, it is important that the rst tire rotation
service be performed when the vehicle has 5,000
to 8,000 miles (8 000 to 13 000 km). Check tires for
ination pressures and wear. SeeTires on page 5-61.
Rotate tires. SeeTire Inspection and Rotation on
page 5-76and “Tire Wear Inspection” inAt Least
Once a Month on page 6-11.When the Change Engine Oil Soon message displays in
the Driver Information Center (DIC), service is required
for the vehicle. Have the vehicle serviced as soon
as possible within the next 600 miles (1 000 km).
It is possible that, if driving under the best conditions,
the engine oil life system may not indicate that
vehicle service is necessary for over a year. However,
the engine oil and lter must be changed at least once
a year and at this time the system must be reset.
Your dealer/retailer has trained service technicians
who will perform this work using genuine parts and
reset the system.
If the engine oil life system is ever reset accidentally,
service the vehicle within 3,000 miles (5 000 km)
since the last service. Remember to reset the oil life
system whenever the oil is changed. SeeEngine Oil Life
System on page 5-21for information on the Engine
Oil Life System and resetting the system.
