1998 Oldsmobile Aurora battery

Replacing Brake System Parts
The braking system on a modern vehicle is complex.
Its 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 bralung
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.
Battery
Every new Aurora 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.
A CAUTION:
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.

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.
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).
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.
I I
Contact your retailer to learn how to prepare your
vehicle for longer storage periods.
Also, for your audio system, see “Theft-Deterrent
Feature’’ in the Index.

Removing the Rear Seat Cushion
To access the battery and rear compartment fuse panels,
the rear seat cushion must be removed. This procedure is
somewhat difficult. You may wish to have your retailer
do this for you.
NOTICE:
The battery and main fuse boxes are located
under the rear seat cushion. The battery’s
ground terminal and some relay wires are
exposed.
To help avoid damage to the battery
and wires, be careful when removing or
reinstalling the seat cushion.
Do not remove
covers from covered parts.
Do not store anything
under the seat, as objects could touch exposed
wires and cause a short.
To Remove the Rear Seat Cushion
1. Pull up on the front of the cushion to release the
front hooks.
2. Pull the cushion up and out toward the front of
To Reinstall the Rear Seat Cushion
the vehicle.

A safety belt that isn’t properly routed through
the seat cushion or is twisted won’t provide the
protection needed in a crash.
If the safety belt
hasn’t been routed through the seat cushion at
all, it won’t be there to work for the next
passenger.
The person sitting in that position
could be badly injured. After reinstalling the seat
cushion, always check to be sure that the safety
belts are properly routed and are not twisted.
1.
2.
3.
Buckle the center passenger position safety belt, and
then route the safety belts through the proper slots in
the seat cushion. Don’t let the safety belt get twisted.
Slide the rear of the cushion up and under the
seatback
so the rear locating guides hook into the
wire loops on the back frame.
With the seat cushion lowered, push rearward and
then press down on the seat cushion until the spring
locks on both ends engage.
4. Check to make sure the safety belts are properly
routed and that
no portion of any safety belt is
trapped under the seat. Also make sure the seat
cushion is secured.
Rear Compartment Fuse Blocks
Once the seat is removed,
you’ll find two
fuse panels
on the driver’s side of the
battery. Each is protected by
a plastic box with four tabs.
Pull up on all four tabs at
the same time to loosen
them and pull off the box.
Of these two panels, the cover on the passenger’s side
fuse panel has an extra plastic cap attachment. You’ll
need
to slide this out of the grooves which hold it there
before removing the rest of the box.
To replace the covers, line the four tabs up and simply
snap them back into place. The extra plastic cap
attachment slides back into place.
