GM Service Manual Online
For 1990-2009 cars only

This vehicle has a standard 12-volt battery and a high-voltage hybrid battery.

When a new standard 12-volt battery is needed, see your dealer/retailer for one that has the replacement number shown on the original battery's label.

Only a trained service technician with the proper knowledge and tools should inspect, test, or replace the hybrid battery. See your dealer/retailer if the hybrid battery needs service.

If an airbag inflates or the vehicle has been in a crash, the vehicle's sensing system might command the automatic hybrid battery disconnect to open. See Replacing Restraint System Parts After a Crash for more information.

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 vehicle is driven infrequently, remove the 12-volt battery black, negative (-) cable from the battery. This helps keep the battery from running down.

Extended Storage: For extended storage of the vehicle, remove the 12-volt battery 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.

Remember to reconnect the battery when ready to drive the vehicle.

If the vehicle is a Two-mode Hybrid, see the Two-mode Hybrid manual for more information.

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.
