1998 CADILLAC SEVILLE Owners Manual

Downloaded from www.Manualslib.com manuals search engine Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come
and
go or be heard all the time your vehicle is moving
(except when you are pushing on the brake
pedal firmly).
r
A CAUTION:
The brake wear warning sound means that soon
your brakes won’t work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
Your vehicle also has electronic wear sensors that let you
know when the brake pads are significantly worn and new
pads are needed. The
CHANGE BRAKE PADS message
will be displayed on the Driver
Information Center when
the brake pads are worn and need
to be replaced. (See
“Change Brake Pads Message” in the Index.)

Brake Adjustment
Every time you apply the brakes, with or without the vehicle moving, your brakes adjust for wear.
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque wheel nuts in the
proper sequence to GM specifications.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection’’ in the Maintenance
Schedule booklet under Part
C “Periodic Maintenance
Inspections.”
Brake Pedal navel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel.
This could be a sign of brake trouble. many parts have to be
of top quality and work well
together if the vehicle is to have really good braking.
Your vehicle was designed and tested with top-quality
GM brake parts. When you replace parts
of your braking
system
-- for example, when your brake linings wear
down and you have to have new ones put in
-- be sure
you get new approved GM replacement parts. If you
don’t, your brakes may no longer work properly. For
example, if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rear brakes can change
-- for the worse. The braking
performance you’ve come to expect can change in many other ways
if someone puts in the wrong replacement
brake parts.

Every new Cadillac has an ACDelco Freedom@ battery. You never have to add water to one
of these. When it’s
time
for a new battery, we recommend an ACDelco
Freedom battery. Get one that has the replacement
number shown on the original battery’s label.
The battery is located under the rear seat cushion.
To
access the battery, see “Removing the Rear Seat
Cushion” in the Index. You don’t need to access the
battery to jump start your vehicle. See “Jump Starting”
in the Index.
‘AC SJ-ION:
-
A battery that isn’t properly vented can let
sulfuric acid fumes into the area under the rear
seat cushion. These fumes can damage your rear
seat safety belt systems. You may not be able to
see this damage, and the safety belts might not
provide the protection needed in
a crash. If a
replacement battery is ever needed, it must be
vented in the same manner as the original
battery. Always make
sure that the vent hose is
properly reattached before reinstalling the
seat cushion.
6-32

Downloaded from www.Manualslib.com manuals search engine To be sure the vent hose (A) is properly attached, the
vent
hose connectors (B) must be securely reattached to
the vent outlets
(C) on each side of the battery, and the
vent assembly grommet
(D) must be secured to the floor
Pan
(E).
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or
more, remove the black, negative
(-) cable from the
battery. This will help keep your battery from
running down.
A CAUTIOY ~
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt
if you
aren’t careful. See “Jump Starting’’ in the Index
for tips on working around a battery without getting hurt.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
Also, for your audio system, see “Theft-Deterrent
Feature”
in the Index.
