Customer Information 367
Scheduling Service
Appointments 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 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 “ Limited 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 do so, your
dealer may offer the following
transportation options:
Shuttle Service
This includes one-way or round-trip
shuttle service within reasonable
time and distance parameters of
your dealer's area.
Public Transportation or Fuel
Reimbursement
If overnight warranty repairs are
needed, and public transportation is
used, the expense must be
supported by original receipts and
within the maximum amount allowed
by GM for shuttle service. If U.S.
customers arrange their own
transportation, limited
reimbursement for reasonable fuel
expenses may be available. Claim
amounts should reflect actual costs
and be supported by original
receipts. See your dealer for
information.
