2008 GMC ENVOY Owner's Manual

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.
Reporting Safety Defects
Reporting Safety Defects to the
United States Government
If you believe that your vehicle has a defect which
could cause a crash or could cause injury or
death, you should immediately inform the National
Highway Traffic Safety Administration (NHTSA)
in addition to notifying General Motors.
If NHTSA receives similar complaints, it may open
an investigation, and if it nds that a safety defect
exists in a group of vehicles, it may order a recall
and remedy campaign. However, NHTSA cannot
become involved in individual problems between
you, your dealer/retailer, or General Motors.
To contact NHTSA, you may call the Vehicle
Safety Hotline toll-free at 1-888-327-4236
(TTY: 1-800-424-9153); go to
http://www.safercar.gov; or write to:
Administrator, NHTSA
400 Seventh Street, SW.
Washington D.C., 20590
You can also obtain other information about motor
vehicle safety from http://www.safercar.gov.

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.
7-18

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.
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 specic 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 alsoOnStar
®System on page 2-48in this
manual for more information.
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
Identication (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.
