Customer Information 13-13
Scheduling Service
Appointments
(U.S. and Canada)
When the vehicle requires
warranty service, contact your
dealer and request an appointment.
By scheduling a service
appointment and advising the
service consultant of your
transportation needs, your
dealer can help minimize
your inconvenience.
If the 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, let them know this,
and ask for instructions.
If your dealer 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 same
day-repair.
Courtesy
Transportation Program
(U.S. and Canada)
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),
extended powertrain, and/or
hybrid‐specific warranties in both
the U.S. and Canada.
Several Courtesy Transportation
options are available to assist in
reducing 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
inconvenience by providing several
transportation options. Depending
on the circumstances, your dealer
can offer one of the following:
Shuttle Service
Shuttle service is the preferred
means of offering Courtesy
Transportation. Dealers may 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
within reasonable time and distance
parameters of your dealer's area.

Reporting Safety
Defects
Reporting Safety Defects
to the United States
Government
If you believe that your vehicle
has a defect which could cause
a crash or could cause injury or
death, you should immediately
inform the National Highway
Traffic Safety Administration
(NHTSA) in addition to notifying
General Motors.
If NHTSA receives similar
complaints, it may open an
investigation, and if it finds that
a safety defect exists in a group
of vehicles, it may order a
recall and remedy campaign.
However, NHTSA cannot
become involved in individual
problems between you, your
dealer, or General Motors.
