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 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 can
inspect the belts and
recommend 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 on page 11
‑ 12 for GM
approved fluids.
