GM Service Manual Online
For 1990-2009 cars only

Your vehicle has one or more maintenance free batteries. When it is time for a new battery, be sure it has the replacement number shown on the original battery's label. We recommend an ACDelco® replacement battery.

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

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 your battery from running down. (If your vehicle has more than one battery, be sure to remove the negative (-) battery cable from each battery.)

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.

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