6-30 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
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
Your new vehicle comes with a maintenance free
ACDelco
battery. When it's time for a new battery, get
one that has the replacement number shown on the original
battery's label. We recommend an ACDelco battery.The battery is located under the rear seat cushion.
To access the battery, see ªRemoving the Rear Seat
Cushionº in the Index. You don't need to access the
battery to jump start your vehicle. See ªJump Startingº
in the Index.
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.

If you ever have a problem on the road and don't have a
spare fuse, you can ªborrowº one that has the same
amperage. Pick some feature of your vehicle that you
can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as you can. You will find a fuse puller
clipped in both of the bussed electrical centers. Snap the
wide end of the fuse puller at the side indentations and
pull the fuse out.
The MaxiFuses are located in two Bussed Electrical
Centers (BEC), one located near the engine compartment
on the passenger's side and the other under the rear seat on
the driver's side. If a MaxiFuse should blow, have your
vehicle serviced by your dealer immediately.Engine Compartment Bussed Electrical
Center (BEC)
The front Bussed Electrical
Center (BEC) is located in
the front of the engine
compartment on the
passenger's side. Lift the
cover to gain access.

Removing the Rear Seat Cushion
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 the vehicle.To reinstall the rear seat cushion:

CAUTION:
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. Buckle the center passenger position safety belt, then
route the safety belts through the proper slots in the
seat cushion. Don't let the safety belts get twisted.
2. 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.3. 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 Underseat Bussed Electrical Center (BEC)
The rear BEC is located
beneath the rear seat on the
driver's side. The rear seat
cushion must be removed to
access the BEC. See
ªRemoving the Rear Seat
Cushionº in the Index.
