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
battery. See Engine Compartment Overview on
page 390 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.
