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.
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.

In addition, once GM collects or receives data,
GM may:
•use the data for GM research needs,
•make it available for research where
appropriate confidentiality is to be maintained
and need is shown, or
•share summary data which is not tied to a
specific 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 the device that stores the data.
Collision Damage Repair
If your 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 will diminish your vehicle’s 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 your vehicle was
originally built. Genuine GM Collision parts are
your best choice to assure that your vehicle’s
designed appearance, durability, and safety are
preserved. The use of Genuine GM parts can help
maintain your GM New Vehicle Warranty.
Recycled original equipment parts may also be
used for repair. These parts are typically removed
from vehicles that were total losses in prior
accidents. 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 your vehicle’s
originally designed appearance and safety
performance, however, the history of these parts is
not known. Such parts are not covered by your
GM New Vehicle Limited Warranty, and any related
failures are not covered by that warranty.
410

Aftermarket collision parts are also available.
These are made by companies other than GM and
may not have been tested for your 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 your GM New Vehicle Limited
Warranty, and any vehicle failure related to such
parts are not covered by that warranty.
Repair Facility
GM also recommends that you choose a collision
repair facility that meets your needs before you
ever need collision repairs. Your GM dealer
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 using
aftermarket 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 an Accident Occurs
Here is what to do if you are involved in an
accident.
•Try to relax and then check to make sure you
are all right. If you are uninjured, make sure
that no one else in your vehicle, or the
other vehicle, is injured.
•If there has been an injury, call 911 for help.
Do not leave the scene of an accident until all
matters have been taken care of. Move your
vehicle only if its position puts you in danger or
you are instructed to move it by a police officer.
•Give only the necessary and requested
information to police and other parties involved
in the accident. Do not discuss your personal
condition, mental frame of mind, or anything
unrelated to the accident. This will help guard
against post-accident legal action.
•If you need roadside assistance, call GM
Roadside Assistance. SeeRoadside
Assistance Program on page 408for more
information.
•If your vehicle cannot be driven, know where
the towing service will be taking it. Get a card
from the tow truck operator or write down the
driver’s name, the service’s name, and the
phone number.
•Remove any valuables from your vehicle before
it is towed away. Make sure this includes your
insurance information and registration if you
keep these items in your vehicle.
•Gather the important information you will need
from the other driver. Things like name,
address, phone number, driver’s license
number, vehicle license plate, vehicle make,
model and model year, Vehicle Identification
Number (VIN), insurance company and policy
number, and a general description of the
damage to the other vehicle.
•If possible, call your insurance company from
the scene of the accident. They will walk you
through the information they will need. If they
ask for a police report, phone or go to the police
department headquarters the next day and you
can get a copy of the report for a nominal fee.
412

In some states/provinces with “no fault”
insurance laws, a report may not be necessary.
This is especially true if there are no injuries
and both vehicles are driveable.
•Choose a reputable collision repair facility for
your vehicle. Whether you select a GM dealer
or a private collision repair facility to fix the
damage, make sure you are comfortable with
them. Remember, you will have to feel
comfortable with their work for a long time.
•Once you have an estimate, read it carefully
and make sure you understand what work will
be performed on your vehicle. If you have a
question, ask for an explanation. Reputable
shops welcome this opportunity.
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 thatany 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.
