GM Service Manual Online
For 1990-2009 cars only

This vehicle has two or more maintenance free batteries. 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.

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 for tips on working around a battery without getting hurt.

Infrequent Usage: If the vehicleis driven infrequently, remove the black, negative (-) cable from each battery. This helps keep the batteries from running down.

Extended Storage: For extended storage of the vehicle, remove the black, negative (-) cable from each battery or use a battery trickle charger. This helps maintain the charge of the batteries over an extended period of time.

When ready to use the vehicle again, refer to the engine starting procedure in the Index.
