GM Service Manual Online
For 1990-2009 cars only

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 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, it might not be possible to remove the ignition key from the ignition switch or shift out of PARK (P). See Shifting Out of Park.

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 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.
