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.

Change (or every 12 months, whichever occurs
rst). Tire Rotation.
Every 15,000 Miles (25 000 km):Engine Air Cleaner
Filter Inspection.
Every 45,000 Miles (75 000 km):Engine Air Cleaner

Be sure to follow the complete scheduled maintenance
on the following pages.

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 engine oil
and lter. 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. A CHANGE ENGINE OIL 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 5-13.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.

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 airbag coverings,
and have them repaired or replaced. (The airbag 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 and Wiper Blades on page 5-83.
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. SeePart D: Recommended Fluids and
Lubricants on page 6-24.
Automatic Transaxle Check
Check the transaxle uid level; add if needed. See
Automatic Transaxle Fluid on page 5-21. A uid 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
specied in Part D.
Body Lubrication Service
Lubricate all body door hinges. Also lubricate all hinges
and latches, including those for the hood, glove box
door and console door. Part D tells you what to
use. More frequent lubrication may be required when
exposed to a corrosive environment.

Additional Program Information
Courtesy Transportation is available during the
Bumper-to-Bumper warranty coverage period, but it is
not part of the New Vehicle Limited Warranty. A
separate booklet entitled Warranty and Owner
Assistance Information furnished with each new vehicle
provides detailed warranty coverage information.
Courtesy Transportation is available only at participating
dealers and all program options, such as shuttle
service, may not be available at every dealer. Please
contact your dealer for specic information about
availability. All Courtesy Transportation arrangements
will be administered by appropriate dealer personnel.
Canadian Vehicles:For warranty repairs during
the Complete Vehicle Coverage period of the General
Motors of Canada New Vehicle Limited Warranty,
alternative transportation may be available under the
Courtesy Transportation Program. Please consult
your dealer for details.
General Motors reserves the right to unilaterally modify,
change or discontinue Courtesy Transportation at
any time and to resolve all questions of claim eligibility
pursuant to the terms and conditions described
herein at its sole discretion.
Vehicle Data Collection and Event
Data Recorders
Your vehicle, like other modern motor vehicles, has a
number of sophisticated computer systems that monitor
and control several aspects of the vehicle’s performance.
Your vehicle uses on-board vehicle computers to monitor
emission control components to optimize fuel economy,
to monitor conditions for airbag deployment and, if so
equipped, to provide anti-lock braking and to help the
driver control the vehicle in difficult driving situations.
Some information may be stored during regular
operations to facilitate repair of detected malfunctions;
other information is stored only in a crash event by
computer systems, such as those commonly called event
data recorders (EDR).
In a crash event, computer systems, such as the Airbag
Sensing and Diagnostic Module (SDM) in your vehicle
may record information about the condition of the vehicle
and how it was operated, such as data related to
engine speed, brake application, throttle position, vehicle
speed, safety belt usage, airbag readiness, airbag
performance, and the severity of a collision. This
information has been used to improve vehicle crash
performance and may be used to improve crash
performance of future vehicles and driving safety. Unlike
the data recorders on many airplanes, these on-board
systems do not record sounds, such as conversation of
vehicle occupants.
