Scheduling Service Appointments
When your vehicle requires warranty service, contact
your dealer/retailer and request an appointment.
By scheduling a service appointment and advising your
service consultant of your transportation needs, your
dealer/retailer can help minimize your inconvenience.
If your vehicle cannot be scheduled into the service
department immediately, keep driving it until it can be
scheduled for service, unless, of course, the problem is
safety-related. If it is, please call your dealership/retailer,
let them know this, and ask for instructions.
If the dealer/retailer requests you to bring the vehicle for
service, you are urged to do so as early in the work
day as possible to allow for the same day repair.
Courtesy Transportation
To enhance your ownership experience, we and our
participating dealers are proud to offer Courtesy
Transportation, a customer support program for vehicles
with the Bumper to Bumper (Base Warranty Coverage
period in Canada) and extended powertrain, and
hybrid specic warranties in both the U.S. and Canada.
Several courtesy transportation options are available
to assist in reducing your inconvenience when warranty
repairs are required.Courtesy Transportation is not a part of the New Vehicle
Limited Warranty. A separate booklet entitled “Warranty
and Owner Assistance Information” furnished with each
new vehicle provides detailed warranty coverage
information.
Transportation Options
Warranty service can generally be completed while you
wait. However, if you are unable to wait, GM helps
to minimize your inconvenience by providing several
transportation options. Depending on the circumstances,
your dealer can offer you one of the following:
Shuttle Service
Participating dealers can provide shuttle service to get
you to your destination with minimal interruption of
your daily schedule. This includes one-way or round trip
shuttle service to a destination up to 10 miles (16 km)
from the dealership.
Public Transportation or Fuel
Reimbursement
If your vehicle requires warranty repairs, and
public transportation is used instead of the dealer’s
shuttle service, the expense must be supported
by original receipts and can only be up to the
maximum amount allowed by GM for shuttle service.
7-10

In addition, for U.S. customers, should you arrange
transportation through a friend or relative, limited
reimbursement for reasonable fuel expenses may be
available. Claim amounts should reect actual costs and
be supported by original receipts. See your dealer for
information regarding the allowance amounts for
reimbursement of fuel or other transportation costs.
Courtesy Rental Vehicle
Your dealer may arrange to provide you with a courtesy
rental vehicle or reimburse you for a rental vehicle that
you obtain if your vehicle is kept for a warranty repair. If
you obtain a rental vehicle on your own, please see your
dealer for the maximum number of days allowed and the
allowance per rental day. Rental reimbursement must be
supported by original receipts. This requires that you sign
and complete a rental agreement and meet state, local,
and rental vehicle provider requirements. Requirements
vary and may include minimum age requirements,
insurance coverage, credit card, etc. You are responsible
for fuel usage charges and may also be responsible for
taxes, levies, usage fees, excessive mileage, or rental
usage beyond the completion of the repair.
It may not be possible to provide a like-vehicle as a
courtesy rental.
Additional Program Information
All program options, such as shuttle service, may not be
available at every dealer. Please contact your dealer
for specic information about availability. All Courtesy
Transportation arrangements will be administered
by appropriate dealer personnel.
General Motors reserves the right to unilaterally modify,
change, or discontinue Courtesy Transportation at
any time and to resolve all questions of claim eligibility
pursuant to the terms and conditions described
herein at its sole discretion.
Collision Damage Repair
If your vehicle is involved in a collision and it is
damaged, have the damage repaired by a qualied
technician using the proper equipment and quality
replacement parts. Poorly performed collision repairs
will diminish your vehicle’s resale value, and safety
performance can be compromised in subsequent
collisions.

Vehicle Data Recording and
Privacy
Your GM vehicle has a number of sophisticated
computers that record information about the vehicle’s
performance and how it is driven. For example, your
vehicle uses computer modules to monitor and control
engine and transmission performance, to monitor the
conditions for airbag deployment and deploy airbags in a
crash and, if so equipped, to provide antilock braking to
help the driver control the vehicle. These modules may
store data to help your dealer/retailer technician service
your vehicle. Some modules may also store data about
how you operate the vehicle, such as rate of fuel
consumption or average speed. These modules may also
retain the owner’s personal preferences, such as radio
pre-sets, seat positions, and temperature settings.
