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 air bag coverings,
and have them repaired or replaced. (The air bag
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
Cleaning the Outside of Your Vehicle on page 5-76.
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
It is not necessary to check the transaxle fluid level. A
transaxle fluid leak is the only reason for fluid loss.
Check for leaks. If a leak occurs, take the vehicle to your
dealer and have it repaired as soon as possible.
Manual Transaxle Check
It is not necessary to check the transaxle fluid level.
Check for leaks. A fluid leak is the only reason for fluid
loss. Have the system inspected and repaired if needed.
Clutch and Brake Pedal Free Play
Check
Check the clutch pedal and brake pedal for free play
and adjust as necessary.

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 air bag 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 or near crash
event by computer systems commonly called event data
recorders (EDR).In a crash or near crash event, computer systems, such
as the Air Bag Sensing and Diagnostic Module (SDM) in
your vehicle may record information about the condition
of the vehicle and how it was operated, such as engine
speed, brake applications, throttle position, vehicle
speed, safety belt usage, air bag readiness, air bag
performance data, 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.
To read this information, special equipment is needed
and access to the vehicle or the SDM is required.
GM will not access information about a crash event or
share it with others other than
•with the consent of the vehicle owner or, if the
vehicle is leased, with the consent of the lessee,
•in response to an official request of police or similar
government office,
•as part of GM’s defense of litigation through the
discovery process, or
•as required by law.
