Replacing Brake System Parts Te braking system on a vehicle is complex. Its many parts have to be of top quality and workwell together if the vehicle is to have really good braking. Your vehicle was designed andtested 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 onesput 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 yourfront 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. See Engine Compartment Overview on page 5-74 for battery location. Warnings 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. 5-46
