Maintenance 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.
(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, chang,
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 power steering lines
and hoses for proper hook-up, binding, leaks,
cracks, chang, 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 Wiper
Blade Replacement on page 349andWindshield
and Wiper Blades on page 392for more
information.
(e)Make sure the safety belt reminder light and
all 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.

At Least Once a Month
Tire Ination Check
Inspect your vehicle’s tires and make sure they
are inated to the correct pressures. Do not forget
to check the spare tire. SeeInation - Tire
Pressure on page 359. Check to make sure the
spare tire is stored securely. SeeChanging a Flat
Tire on page 374.
Tire Wear Inspection
Tire rotation may be required for high mileage
highway drivers prior to the Engine Oil Life System
service notication. Check the tires for wear
and, if necessary, rotate the tires. SeeTire
Inspection and Rotation on page 364.
At Least Once a Year
Starter Switch Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough
room around the vehicle.
2. Firmly apply both the parking brake and the
regular brake. SeeParking Brake on page 120.
Do not use the accelerator pedal, and be ready
to turn off the engine immediately if it starts.
3. Try to start the engine in each gear.
The vehicle should start only in PARK (P)
or NEUTRAL (N). If the vehicle starts in any
other position, contact your dealer/retailer
for service.

Automatic Transmission Shift Lock
Control System Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough
room around the vehicle. It should be parked
on a level surface.
2. Firmly apply the parking brake. SeeParking
Brake on page 120.
Be ready to apply the regular brake
immediately if the vehicle begins to move.
3. With the engine off, turn the ignition to RUN,
but do not start the engine. Without applying
the regular brake, try to move the shift lever out
of PARK (P) with normal effort. If the shift lever
moves out of PARK (P), contact your dealer/
retailer for service.
Ignition Transmission Lock Check
While parked, and with the parking brake set,
try to turn the ignition to OFF in each shift lever
position.
The ignition should turn to OFF only when the
shift lever is in PARK (P).
The ignition key should come out only in OFF.

room in front of your vehicle in case it
begins to roll. Be ready to apply the
regular brake at once should the vehicle
begin to move.

Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular
brake, set the parking brake.
To check the parking brake’s holding ability:
With the engine running and transmission in
NEUTRAL (N), slowly remove foot pressure
from the regular brake pedal. Do this until the
vehicle is held by the parking brake only.
To check the PARK (P) mechanism’s holding
ability: With the engine running, shift to
PARK (P). Then release the parking brake
followed by the regular brake.
Contact your dealer/retailer if service is required.

Vehicle Data Recording and
Privacy
Your GM vehicle has a number of sophisticated
computers that record information about the
vehicle’s performance and how it is driven. For
example, your vehicle uses computer modules to
monitor and control engine and transmission
performance, to monitor the conditions for airbag
deployment and deploy airbags in a crash and, if so
equipped, to provide anti-lock braking to help the
driver control the vehicle. These modules may store
data to help your dealer/retailer technician service
your vehicle. Some modules may also store data
about how you operate the vehicle, such as rate of
fuel consumption or average speed. These
modules may also retain the owner’s personal
preferences, such as radio pre-sets, seat positions,
and temperature settings.
Event Data Recorders
Some information about your vehicle’s performance
and how it is driven may be recorded on various
modules if a crash occurs. Some people refer to
these modules asevent data recorders (EDRs).
These modules may record several seconds of
pre-crash and crash data, such as data related
toengine speed, brake application, throttle
position, vehicle speed, yaw rate, steering
wheel angle, lateral acceleration, safety belt
usage, airbag readiness, airbag performance
andthe severity of the collision.Unlike the ight
data recorders on airplanes, these modules do not
record sounds or conversations.
To retrieve this data, special equipment and
access to the vehicle or the module that stores
the data are required. Certain data may also
be sent to or retrieved by OnStar
®(see below).
GM will not access this information or share it with
others except: 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
partof GM’s defense of litigation through the
discovery process; or, as required by law.
