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. If the battery has a very low charge or is dead, you may not be able to remove the ignition key from the ignition switch or shift out of PARK (P). Refer to Shifting Out of Park (P) on page 117. 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 the battery from running down. 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 346 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. {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 382 for tips on working around a battery without getting hurt. 381
