Battery; Replacing Brake System Parts - Pontiac 2005 Bonneville Owner's Manual

Replacing Brake System Parts

The braking system on a 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 braking
system —for example, when your brake linings wear
down and you need new ones put in — be sure you get
new approved GM replacement parts. If you do not,
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 have come to expect can change in
many other ways if someone puts in the wrong
replacement brake parts.

Battery

Your vehicle has a maintenance free battery. When it is
time for a new battery, get one that has the replacement
number shown on the original battery's label.

replacement battery.
The battery is located under the rear seat cushion.
To access the battery, see "Removing the Rear Seat
Cushion" under Rear Underseat Fuse Block on
page 5-116. You do not need to access the battery to
jump start your vehicle. See Jump Starting (3.8L V6
Engine) on page 5-59 or Jump Starting (4.6L V8 Engine)
on page 5-63.
CAUTION:
{
A battery that is not 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.
