340 SERVICE AND MAINTENANCE
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

to safe driving.

chirping, grinding, or squealing
noises, or difficulty stopping. .

components. See Recommended Fluids
and Lubricants 0343 for GM approved
fluids.

fluid levels should be checked at
every fuel fill.

come on to indicate that fluids
may be low and need to be filled.

Customer Information
Customer Satisfaction
Procedure
Your satisfaction and goodwill are
important to your dealer and to
Cadillac. 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.
