Part C: Periodic Maintenance
Inspections
Listed in this part are inspections and services which
should be performed at least twice a year (for instance,
each spring and fall).You should let your dealer’s
service department do these jobs. Make sure any
necessary repairs are completed at once.
Proper procedures to perform these services may be
found in a service manual. SeeService Publications
Ordering Information on page 7-12.
Steering, Suspension and Front
Drive Axle Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chang, etc. Clean and then inspect the
drive axle boot seals for damage, tears or leakage.
Replace seals if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near the exhaust system. Look for broken, damaged,
missing or out-of-position parts as well as open seams,
holes, loose connections or other conditions which
could cause a heat build-up in the oor pan or could let
exhaust fumes into the vehicle. SeeEngine Exhaust
on page 2-29.
Fuel System Inspection
Inspect the complete fuel system for damage or leaks.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
ttings and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of
the cooling system and pressure cap is recommended
at least once a year.
6-26

Throttle System Inspection
Inspect the throttle 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
and cruise control cables.
Transfer Case and Front Axle
(All-Wheel Drive) Inspection
Every 12 months, or at engine oil change intervals,
check front axle and transfer case and add lubricant
when necessary. A uid loss could indicate a problem.
Check and have it repaired, if needed. Check vent
hose at transfer case for kinks and proper installation.
Brake System Inspection
Inspect the complete system. 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. Check parking
brake adjustment. You may need to have your brakes
inspected more often if your driving habits or conditions
result in frequent braking.
6-27

Public Transportation or Fuel
Reimbursement
If your vehicle requires overnight warranty repairs,
reimbursement (ve day maximum) may be available
for the use of public transportation such as taxi or bus.
In addition, should you arrange transportation through
a friend or relative, reimbursement for reasonable
fuel expenses (ve day maximum) may be available.
Claim amounts should reect actual costs and be
supported by original receipts.
Courtesy Rental Vehicle
Your dealer may arrange to provide you with a courtesy
rental vehicle or reimburse you for a rental vehicle
you obtained if your vehicle is kept for a warranty
repair. Reimbursement will be limited to a maximum
of $30.00 a day and must be supported by receipts.
This requires that you sign and complete a rental
agreement and meet state, local and rental vehicle
provider requirements. Requirements vary and
may include minimum age requirements, insurance
coverage, credit card, etc. You are responsible for
fuel usage charges and may also be responsible for
taxes, levies, usage fees, excessive mileage or
rental usage beyond the completion of the repair.
Generally it is not possible to provide a like-vehicle
as a courtesy rental.
Additional Program Information
Courtesy Transportation is available during the
Bumper-to-Bumper warranty coverage period, but it
is notpart 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 you 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 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 thanwith 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.
In addition, once GM collects or receives data, GM may
use the data for GM research needs,
make it available for research where appropriate
condentiality is to be maintained and need is
shown, or
share summary data which is not tied to a
specic vehicle with non-GM organizations for
research purposes.
Others, such as law enforcement, may have access to
the special equipment that can read the information
if they have access to the vehicle or SDM.
