(1) Or every two years, whichever
comes first. More frequent
replacement may be needed if the
vehicle is driven in areas with heavy
traffic, areas with poor air quality,
or areas with high dust levels.
Replacement may also be needed if
there is a reduction in air flow,
excessive window fogging, or odors.
(2) Check all fuel and vapor lines
and hoses for proper hook-up,
routing, and condition.

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.

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,

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 NewVehicle 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.
Repair Facility
GM also recommends that you
choose a collision repair facility that
meets your needs before you ever
need collision repairs. Your 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

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-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.

provider must also have coverage,
network capacity, reception, and
technology compatible with OnStar
services. Service involving location

hardware. OnStar services may not
work if the OnStar equipment is not
properly installed or it has not been
properly maintained. If equipment or
software is added, connected,
or modified, OnStar services may
not work. Other problems beyond
the control of OnStar may prevent
service 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.
