Service and Appearance Care When parts of the braking system are replaced - for example, when the brake linings wear down and new ones are installed - be sure to get new approved replacement parts. If this is not done, the brakes might not work properly. For example, if someone puts in brake linings that are wrong for the vehicle, the balance between the front and rear brakes can change - for the worse. The braking performance expected can change in many other ways if the wrong replacement brake parts are installed. 5-33 Battery This vehicle has a maintenance free battery. When it is time for a new battery, see your dealer/retailer for one that has the replacement number shown on the original battery's label. 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 { 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 5-34 for tips on working around a battery without getting hurt. Infrequent Usage: If the vehicle is driven infrequently, remove the black, negative (−) cable from the battery. This helps keep the battery from running down. Extended Storage: For extended storage of the vehicle, remove the black, negative (−) cable from the battery or use a battery trickle charger. This helps maintain the charge of the battery over an extended period of time.
