Battery Your 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 5-12 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. If the battery has a very low charge or is dead, you might not be able to remove the ignition key from the ignition switch or shift out of PARK (P). See Shifting Out of PARK (P) on page 2-35. 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 5-50 for tips on working around a battery without getting hurt. Infrequent Usage: If you drive your vehicle infrequently, remove the black, negative (−) cable from the battery. This will help keep the battery from running down. Extended Storage: For extended storage of your vehicle, remove the black, negative (−) cable from the battery or use a battery trickle charger. This will help maintain the charge of the battery over an extended period of time. 5-49
