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. We
recommend an ACDelco
Engine Compartment Overview on page 5-12 for
battery location.
Warning: Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.

If you are 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.

Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
