levies, usage fees, excessive mileage,

It may not be possible to provide a

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,
or discontinue Courtesy
Transportation at any time and to
resolve all questions of claim

conditions described herein at its sole
discretion.
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 diminishthe 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.
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 center
that has GM-trained technicians and
comparable equipment.
