Maintenance Footnotes
(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, cha ng,
etc. Inspect disc brake pads for wear and rotors
for surface condition. Inspect other brake
parts, including calipers, parking brake, etc.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing
parts or signs of wear. Inspect electric power
steering cables for proper hook-up, binding,
cracks, cha ng, etc. Inspect hydraulic power
steering lines and hoses for proper hook-up,
binding, leaks, cracks, cha ng, etc.
(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings and clamps; replace
with genuine parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside
of the radiator and air conditioning condenser is
recommended at least once a year.
(d)Inspect wiper blades for wear, cracking,
or contamination. Clean the windshield and wiper
blades, if contaminated. Replace wiper blades
that are worn or damaged. See Windshield WiperBlade Replacement on page 394andWindshield
and Wiper Blades on page 440for more
information.
(e)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.
(f)Lubricate all key lock cylinders, door hinges
and latches, hood hinges and latches, and trunk lid
hinges and latches. More frequent lubrication
may be required when exposed to a corrosive
environment. Applying silicone grease on
weatherstrips with a clean cloth will make them
last longer, seal better, and not stick or squeak.
(g)Check system for interference or binding
and for damaged or missing parts. Replace parts
as needed. Replace any components that
have high effort or excessive wear. Do not
lubricate accelerator or cruise control cables.

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 the vehicle
has the Anti-lock Brake System (ABS), 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.
To read this information, special equipment
is needed and access to the vehicle or
the device that stores the data 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.
