Maintenance Footnotes
(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 GM 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.

At Least Once a Month
Tire Ination Check
Visually inspect your vehicle’s tires and make
sure they are inated to the correct pressures.
Do not forget to check the spare tire. See
Ination - Tire Pressure on page 447. Check to
make sure the spare tire is stored securely.
SeeChanging a Flat Tire on page 465.
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 453.
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 126.
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 GM Goodwrench
®
dealer for service.
514

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 126.
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 GM Goodwrench
®dealer for service.
Ignition Transmission Lock Check
While parked, and with the parking brake set, try
to turn the ignition to LOCK in each shift lever
position.
The ignition should turn to LOCK only when
the shift lever is in PARK (P).
The ignition key should come out only
in LOCK.
Contact your GM Goodwrench
®dealer if service
is required.
515

Parking Brake and Automatic
Transmission Park (P) Mechanism Check
{CAUTION:
When you are doing this check, your
vehicle could begin to move. You or
others could be injured and property
could be damaged. Make sure there is
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 GM Goodwrench
®dealer if service is
required.
Underbody Flushing Service
At least every spring, use plain water to ush any
corrosive materials from the underbody. Take
care to clean thoroughly any areas where mud
and other debris can collect.

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. If your vehicle is
equipped with StabiliTrak
®, steering performance,
including yaw rate, steering wheel angle, and
lateral acceleration, is also recorded. 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.
