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
0487.
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? 064.
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
