to look for that may indicate
services are required.

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.

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.

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.

Customer Information 327
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-like situations, 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 and no personal
data (e.g., name, gender, age, and
crash location) are 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.
GM will not access these 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 by 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 the vehicle is equipped with
OnStar®and has an active
subscription, additional data may be
collected through the OnStar
system. This includes information
about the vehicle’s operation;
collisions involving the vehicle; the
use of the vehicle and its features;
and, in certain situations, the
location and approximate GPS
speed of the vehicle. Refer to the

phone network congestion or
jamming—may prevent service.

hard-of-hearing, or speech-impaired
customers while in the vehicle. The
available dealer-installed TTY
system can provide in-vehicle access to all OnStar services,
except Virtual Advisor and OnStar
Turn-by-Turn Navigation.
OnStar Personal Identification
Number (PIN)
A PIN is needed to access some
OnStar services. The PIN will need
to be changed the first time when
speaking with an Advisor. To
change the OnStar PIN, contact an
OnStar Advisor by pressing
Qor
calling 1-888-4ONSTAR.
Warranty
OnStar equipment may be
warranted as part of the vehicle
warranty.
Languages
The vehicle can be programmed to
respond in multiple languages.
Press
Qand ask for an Advisor.
Advisors are available in English,
Spanish, and French. Available
languages may vary by country.
Potential Issues
OnStar cannot perform Remote
Door Unlock or Stolen Vehicle
Assistance after the vehicle has
been off continuously for 10 days
without an ignition cycle. If the
vehicle has not been started for
five days, OnStar can contact
Roadside Assistance or a locksmith
to help gain access to the vehicle.
Global Positioning
System (GPS)
. Obstruction of the GPS can
occur in a large city with tall
buildings; in parking garages;
around airports; in tunnels and
underpasses; or in an area with
very dense trees. If GPS signals
are not available, the OnStar
system should still operate to
call OnStar. However, OnStar
could have difficulty identifying
the exact location.
. In emergency situations, OnStar
can use the last stored GPS
location to send to emergency
responders.
