any vehicle failure related to such
parts are not covered by that
warranty.
Repair Facility
We recommend that you choose a
collision repair facility that meets
your needs before you ever need
collision repairs. Your dealer/retailer
may have a collision repair center
with GM-trained technicians and
state of the art equipment, or be
able to recommend a collision repair
center that has GM-trained
technicians and comparable
equipment.
Insuring Your Vehicle
Protect your investment in your GM
vehicle with comprehensive and
collision insurance coverage. There
are significant differences in the
quality of coverage afforded by
various insurance policy terms.
Many insurance policies provide
reduced protection to your GM
vehicle by limiting compensation for
damage repairs by usingaftermarket collision parts. Some
insurance companies will not
specify aftermarket collision parts.
When purchasing insurance, we
recommend that you assure your
vehicle will be repaired with GM
original equipment collision parts.
If such insurance coverage is not
available from your current
insurance carrier, consider switching
to another insurance carrier.
If your vehicle is leased, the leasing
company may require you to have
insurance that assures repairs with
Genuine GM Original Equipment
Manufacturer (OEM) parts or
Genuine Manufacturer replacement
parts. Read your lease carefully, as
you may be charged at the end of
your lease for poor quality repairs.
If a Crash Occurs
If there has been an injury, call
emergency services for help. Do not
leave the scene of a crash until all
matters have been taken care of.
Move the vehicle only if its position
puts you in danger, or you are
instructed to move it by a police
officer.
Give only the necessary information
to police and other parties involved
in the crash.
For emergency towing see

Managing the Vehicle Damage
Repair Process
In the event that your vehicle
requires damage repairs, GM
recommends that you take an active
role in its repair. If you have a
pre-determined repair facility of
choice, take your vehicle there,
or have it towed there. Specify to
the facility that any required
replacement collision parts be
original equipment parts, either new
Genuine GM parts or recycled
original GM parts. Remember,
recycled parts will not be covered by
your GM vehicle warranty. Insurance pays the bill for the repair,
but you must live with the repair.
Depending on your policy limits,
your insurance company may
initially value the repair using
aftermarket parts. Discuss this with
your repair professional, and insist
on Genuine GM parts. Remember if
your vehicle is leased you may be
obligated to have the vehicle
repaired with Genuine GM parts,
even if your insurance coverage
does not pay the full cost.
If another party's insurance
company is paying for the repairs,
you are not obligated to accept a
repair valuation based on that
insurance company's collision policy
repair limits, as you have no
contractual limits with that company.
In such cases, you can have control
of the repair and parts choices as
long as cost stays within reasonable
limits.

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 antilock
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
This vehicle has an Event Data
Recorder (EDR). The main purpose
of an EDR is to record, in certain
crash or near crash-like situations,
such as an airbag 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
pressing the accelerator and/or
brake pedal
.How fast the vehicle was
traveling This data can help provide a better
understanding of the circumstances
in which crashes and injuries occur.
Important:
EDR data is recorded
by your vehicle only if a non-trivial
crash situation occurs; no data is
recorded by the EDR under normal
driving conditions and no personal
data (e.g., name, gender, age, and
crash location) is recorded.
However, other parties, such as law
enforcement, could combine the
EDR data with the type of
personally identifying data routinely
acquired during a crash
investigation.
To read data recorded by an EDR,
special equipment is required, and
access to the vehicle or the EDR is
needed. In addition to the vehicle
manufacturer, other parties, such as
law enforcement, that have the
special equipment, can read the
information if they have access to
the vehicle or the EDR.

12-16 Customer Information
GM will not access this data 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 part of
GM's defense of litigation through
the discovery process; or, as
required by law. Data that GM
collects or receives may also be
used for GM research needs or may
be made available to others for
research purposes, where a need is
shown and the data is not tied to a
specific vehicle or vehicle owner.
OnStar®
If your vehicle has OnStar and you
subscribe to the OnStar services,
please refer to the OnStar Terms
and Conditions for information on
data collection and use. See also

Navigation System
If your vehicle has a navigation
system, use of the system may
result in the storage of destinations,
addresses, telephone numbers, and
other trip information. Refer to the
navigation system operating manual
for information on stored data and
for deletion instructions.
Radio Frequency
Identification (RFID)
RFID technology is used in some
vehicles for functions such as tire
pressure monitoring and ignition
system security, as well as in
connection with conveniences such
as key fobs for remote door locking/
unlocking and starting, and
in-vehicle transmitters for garage
door openers. RFID technology in
GM vehicles does not use or record
personal information or link with any
other GM system containing
personal information.
Radio Frequency
Statement
This vehicle has systems that
operate on a radio frequency that
comply with Part 15 of the Federal
Communications Commission (FCC)
Rules and with RSS-210/211 of
Industry and Science Canada.
Operation is subject to the following
two conditions:
1. The device may not cause interference.
2. The device must accept any interference received, including
interference that may cause
undesired operation of the
device.
Changes or modifications to any of
these systems by other than an
authorized service facility could void
authorization to use this equipment.
