{WARNING
Performing maintenance work can
be dangerous and can cause
serious injury. Perform
maintenance work only if the
required information, proper tools,
and equipment are available.
If they are not, see your dealer to
have a trained technician do the
work. SeeDoing Your Own
Service Work on page 10‑4.

pressures. See Tire Pressure on
page 10‑56.

Engine Oil Change
When the CHANGE ENGINE OIL
SOON message displays, have the
engine oil and filter changed within
the next 1 000 km/600 mi. If driven
under the best conditions, the
engine oil life system might not
indicate the need for vehicle service
for more than a year. The engine oil
and filter must be changed at least
once a year and the oil life system
must be reset. Your trained dealer
technician can perform this work.
If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 mi since the
last service. Reset the oil life
system when the oil is changed.
See Engine Oil Life System on
page 10‑10.

Additional
Maintenance and Care
Your vehicle is an important
investment and caring for it properly
may help to avoid future costly
repairs. To maintain vehicle
performance, additional
maintenance services may be
required. It is recommended
that your dealer perform these
services —their trained dealer
technicians know your vehicle best.
Your dealer can also perform a
thorough assessment with a
multi‐point inspection to recommend
when your vehicle may need
attention. The following list is
intended to explain the services and
conditions to look for that may
indicate services are required.

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.

13-14 Customer Information
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.
The Courtesy Transportation
program is no longer available for
cutaway vehicles.
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” furnishedwith 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.
Public Transportation or Fuel
Reimbursement
If the vehicle requires overnight
warranty repairs, and public
transportation is used instead of
your 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. 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 reflect 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.
