Mexico-9955992) - 2017 - crc - 5/3/16
Customer Information 465
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.
Insuring the Vehicle
Protect your investment in the 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 the GM
vehicle by limiting compensation for
damage repairs through the use of
aftermarket collision parts. Some
insurance companies will not
specify aftermarket collision parts.
When purchasing insurance, we
recommend that you ensure that the
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 the vehicle is leased, the leasing
company may require you to have
insurance that ensures repairs with
Genuine GM Original Equipment
Manufacturer (OEM) parts or
Genuine Manufacturer replacementparts. Read the lease carefully, as
you may be charged at the end of
the lease for poor quality repairs.
If a Crash Occurs
If there has been an injury, call
emergency services for help. Do not
leave the scene of a crash until all
matters have been taken care of.
Move the vehicle only if its position
puts you in danger, or you are
instructed to move it by a police
officer.
Give only the necessary information
to police and other parties involved
in the crash.
For emergency towing see
Roadside Assistance
Program

Gather the following information:
. Driver name, address, and
telephone number.
. Driver license number.
. Owner name, address, and
telephone number.
. Vehicle license plate number.
