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
®
replacement
battery. See Engine Compartment Overview on
page 5-10 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.
Vehicle Storage
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.

CAUTION:
Batteries have acid that can burn you and
gas that can explode. You can be badly hurt if
you are not careful. See Jump Starting on
page 5-40 for tips on working around a battery
without getting hurt.
