CUSTOMER INFORMATION 409
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
Service 0405.
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.

Will You See after an Airbag Inf lates?
0 59.
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.

410 CUSTOMER INFORMATION
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.
