SERVICE AND MAINTENANCE 329
Additional Maintenance
and Care
Your vehicle is an important
investment and caring for it properly
may help to avoid future costly
repairs. To maintain vehicle
performance, additional maintenance
services may be required.
It is recommended that your dealer
perform these services—their trained
dealer technicians know your vehicle
best. Your dealer can also perform a
thorough assessment with a
multi-point inspection to recommend
when your vehicle may need
attention.
The following list is intended to
explain the services and conditions to
look for that may indicate services are
required.
Battery
The 12-volt battery supplies power to
start the engine and operate any
additional electrical accessories. .
To avoid break-down or failure to
start the vehicle, maintain a
battery with full cranking power.
. Trained dealer technicians have
the diagnostic equipment to test
the battery and ensure that the
connections and cables are
corrosion-free.
Belts
. Belts may need replacing if they
squeak or show signs of cracking
or splitting.
. Trained dealer technicians have
access to tools and equipment to
inspect the belts and recommend
adjustment or replacement when
necessary.
Brakes
Brakes stop the vehicle and are crucial
to safe driving.
. Signs of brake wear may include
chirping, grinding, or squealing
noises, or difficulty stopping. .
Trained dealer technicians have
access to tools and equipment to
inspect the brakes and recommend
quality parts engineered for the
vehicle.
Fluids
Proper fluid levels and approved fluids
protect the vehicle’s systems and
components. See Recommended Fluids
and Lubricants 0332 for GM approved
fluids.
. Engine oil and windshield washer
fluid levels should be checked at
every fuel fill.
. Instrument cluster lights may
come on to indicate that fluids
may be low and need to be filled.
Hoses
Hoses transport fluids and should be
regularly inspected to ensure that
there are no cracks or leaks. With a
multi-point inspection, your dealer
can inspect the hoses and advise if
replacement is needed.

346 CUSTOMER INFORMATION
Courtesy Rental Vehicle
For an overnight warranty repair, the
dealer may provide an available
courtesy rental vehicle or provide for
reimbursement of a rental vehicle.
Reimbursement is limited and must
be supported by original receipts as
well as a signed and completed rental
agreement and meet state/provincial,
local, and rental vehicle provider
requirements. Requirements vary and
may include minimum age
requirements, insurance coverage,
credit card, etc. Additional fees such
as fuel usage charges, taxes, levies,
usage fees, excessive mileage, or rental
usage beyond the completion of the
repair are also your responsibility.
It may not be possible to provide a
like vehicle as a courtesy rental.
Additional Program Information
All program options, such as shuttle
service, may not be available at every
dealer. Contact your dealer for specific
availability.
General Motors reserves the right to
unilaterally modify, change,
or discontinue CourtesyTransportation at any time and to
resolve all questions of claim
eligibility pursuant to the terms and
conditions described herein at its sole
discretion.
Collision Damage Repair
If the vehicle is involved in a collision
and it is damaged, have the damage
repaired by a qualified technician
using the proper equipment and
quality replacement parts. Poorly
performed collision repairs diminish
the vehicle resale value, and safety
performance can be compromised in
subsequent collisions.
Collision Parts
Genuine GM Collision parts are new
parts made with the same materials
and construction methods as the parts
with which the vehicle was originally
built. Genuine GM Collision parts are
the best choice to ensure that the
vehicle's designed appearance,
durability, and safety are preserved.
The use of Genuine GM parts can help
maintain the GM New Vehicle Limited
Warranty.
Recycled original equipment parts
may also be used for repair. These
parts are typically removed from
vehicles that were total losses in prior
crashes. In most cases, the parts being
recycled are from undamaged sections
of the vehicle. A recycled original
equipment GM part may be an
acceptable choice to maintain the
vehicle's originally designed
appearance and safety performance;
however, the history of these parts is
not known. Such parts are not covered
by the GM New Vehicle Limited
Warranty, and any related failures are
not covered by that warranty.
Aftermarket collision parts are also
available. These are made by
companies other than GM and may
not have been tested for the vehicle.
As a result, these parts may fit poorly,
exhibit premature durability/corrosion
problems, and may not perform
properly in subsequent collisions.
Aftermarket parts are not covered by
the GM New Vehicle Limited
Warranty, and any vehicle failure
related to such parts is not covered by
that warranty.

Vehicle Data Recording
and Privacy
The vehicle has a number of
computers that record information
about the vehicle’s performance and
how it is driven. For example, the
vehicle uses computer modules to
monitor and control engine and
transmission performance, to monitor
the conditions for airbag deployment
and deploy them in a crash, and,
if equipped, to provide antilock
braking to help the driver control the
vehicle. These modules may store data
to help the dealer technician service
the vehicle. Some modules may also
store data about how the vehicle is
operated, such as rate of fuel
consumption or average speed. These
modules may retain personal
preferences, such as radio presets, seat
positions, and temperature settings.
Event Data Recorders
This vehicle is equipped with an event
data recorder (EDR). The main
purpose of an EDR is to record, in
certain crash or near crash-likesituations, such as an air bag
deployment or hitting a road obstacle,
data that will assist in understanding
how a vehicle’s systems performed.
The EDR is designed to record data
related to vehicle dynamics and safety
systems for a short period of time,
typically 30 seconds or less. The EDR
in this vehicle is designed to record
such data as:
.
How various systems in your
vehicle were operating;
. Whether or not the driver and
passenger safety belts were
buckled/fastened;
. How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
. How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur.
Note
EDR data are recorded by your vehicle
only if a non-trivial crash situation
occurs; no data are recorded by the
EDR under normal driving conditions

problems beyond the control of
OnStar—such as hills, tall buildings,
tunnels, weather, electrical system
design and architecture of the vehicle,
damage to the vehicle in a crash,
or wireless phone network congestion
or jamming —may prevent service.
