Service and Maintenance 345
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. Battery
The 12-volt battery supplies power
to start the engine and operate any
additional electrical accessories.
.
To avoid break-down or failure to
start the vehicle, maintain a
battery with full cranking power.
. Trained dealer technicians have
the diagnostic equipment to test
the battery and ensure that the
connections and cables are
corrosion-free.
Belts
. Belts may need replacing if they
squeak or show signs of
cracking or splitting.
. Trained dealer technicians have
access to tools and equipment
to inspect the belts and
recommend adjustment or
replacement when necessary. Brakes
Brakes stop the vehicle and are
crucial to safe driving.
.
Signs of brake wear may include
chirping, grinding, or squealing
noises, or difficulty stopping.
. Trained dealer technicians have
access to tools and equipment
to inspect the brakes and
recommend quality parts
engineered for the vehicle.
Fluids
Proper fluid levels and approved
fluids protect the vehicle’s systems
and components. See
Recommended Fluids and
Lubricants 0348 for GM approved
fluids.
. Engine oil and windshield
washer fluid levels should be
checked at every fuel fill.
. Instrument cluster lights may
come on to indicate that fluids
may be low and need to be
filled.

368 Customer Information
.Whether or not the driver and
passenger safety belts were
buckled/fastened;
. How far (if at all) the driver was
depressing the accelerator and/
or brake pedal; and,
. How fast the vehicle was
traveling.
These 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 these 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 service
plan, additional data may be
collected and transmitted through
the OnStar system. This includes
information about the vehicle’s
operation; collisions involving the
vehicle; the use of the vehicle and
its features, including infotainment;
and the location and approximate
GPS speed of the vehicle. Refer to
the OnStar Terms and Conditions
and Privacy Statement on the
OnStar website.
See
OnStar Additional Information
0 371.
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.
