13-14 Customer Information
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 by using
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 replacement
parts. 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
(U.S. and Canada) on page 13‑8
or
Roadside Assistance Program
(Mexico) on page 13‑10. Gather the following information:
.Driver name, address, and
telephone number.
.Driver license number.
.Owner name, address, and
telephone number.
.Vehicle license plate number.
.Vehicle make, model, and
model year.
.Vehicle Identification
Number (VIN).
.Insurance company and policy
number.
.General description of the
damage to the other vehicle.
Choose a reputable repair facility
that uses quality replacement parts.
See “Collision Parts” earlier in this
section.
If the airbag has inflated, see What
Will You See After an Airbag
Inflates? on page 3‑35.

Managing the Vehicle Damage
Repair Process
In the event that the 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 the 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 the 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
the repair professional, and insist
on Genuine GM parts. Remember,
if the 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 the cost stays
within reasonable limits.
