11-2 Service and Maintenance The Tire Rotation and Required
Services are the responsibility of the
vehicle owner. It is recommended to
have your dealer perform these
services every 12 000 km/7,500 mi.
Proper vehicle maintenance helps to
keep the vehicle in good working
condition, improves fuel economy,
and reduces vehicle emissions.

vehicles, maintenance needs vary.
There may need to be more
frequent checks and services.

those listed under Additional
Required Services, are for
vehicles that: .

within recommended limits on
the Tire and Loading Information
label. See Vehicle Load Limits

Are driven on reasonable road
surfaces within legal driving
limits. .
Use the recommended fuel. See
Fuel on page 9-63 .

schedule, some vehicles require
service more often. Severe service
is for vehicles that are: .
Mainly driven in heavy city traffic
in hot weather. .
Mainly driven in hilly or
mountainous terrain. .
Frequently towing a trailer. .
Used for high-speed or
competitive driving. .
Used for taxi, police, or delivery
service. { WarningPerforming maintenance work can
be dangerous and can cause
serious injury. Perform

have a trained technician do the
work. See Doing Your Own
Service Work on page 10-3 .

Procedure Your satisfaction and goodwill are
important to your dealer and to
GMC. Normally, any concerns with
the sales transaction or the
operation of the vehicle will be
resolved by your dealer's sales or
service departments. Sometimes,
however, despite the best intentions
of all concerned, misunderstandings
can occur. If your concern has not
been resolved to your satisfaction,
the following steps should be taken:
STEP ONE: Discuss your concern
with a member of dealership
management. Normally, concerns
can be quickly resolved at that level.
If the matter has already been
reviewed with the sales, service,
or parts manager, contact the owner
of your dealership or the general
manager.

13-8 Customer Information
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.
Courtesy Rental Vehicle
For an overnight warranty repair, the
dealer may provide an available
courtesy rental vehicle or provide for
reimbursement of a rental vehicle.
Reimbursement is limited and must
be supported by original receipts as
well as a signed and completed
rental agreement and meet state/
provincial, local, and rental vehicle
provider requirements.
Requirements vary and may include
minimum age requirements,
insurance coverage, credit card, etc.
Additional fees such as fuel usage
charges, taxes, levies, usage fees,
excessive mileage, or rental usage
beyond the completion of the repair
are also your responsibility.
It may not be possible to provide a
like vehicle as a courtesy rental.

Customer Information 13-15These data can help provide a
better understanding of the
circumstances in which crashes and
injuries occur. NOTE: EDR data are
recorded by your vehicle only if a
non-trivial crash situation occurs; no
data are recorded by the EDR under
normal driving conditions and no
personal data (e.g., name, gender,
age, and crash location) are
recorded. However, other parties,
such as law enforcement, could
combine the EDR data with the type
of personally identifying data
routinely acquired during a crash
investigation.
To read data recorded by an EDR,
special equipment is required, and
access to the vehicle or the EDR is
needed. In addition to the vehicle
manufacturer, other parties, such as
law enforcement, that have the
special equipment, can read the
information if they have access to
the vehicle or the EDR.
GM will not access this data or
share it with others except: with the
consent of the vehicle owner or, if the vehicle is leased, with the
consent of the lessee; in response
to an official request by police or
similar government office; as part of
GM's defense of litigation through
the discovery process; or, as
required by law. Data that GM
collects or receives may also be
used for GM research needs or may
be made available to others for
research purposes, where a need is
shown and the data is not tied to a
specific vehicle or vehicle owner.
OnStar ®
If the vehicle is equipped with
OnStar ®
and has an active
subscription, additional data may be
collected through the OnStar
system. This includes information
about the vehicle ’ s operation;
collisions involving the vehicle; the
use of the vehicle and its features;
and, in certain situations, the
location and approximate GPS
speed of the vehicle. Refer to the OnStar Terms and Conditions and
Privacy Statement on the OnStar
website.
Infotainment System If the vehicle is equipped with a
navigation system as part of the
infotainment system, use of the
system may result in the storage of
destinations, addresses, telephone
numbers, and other trip information.
See the infotainment manual for
information on stored data and for
deletion instructions.
