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

For battery replacement, see your dealer or the service manual. To purchase a service manual, see Service and Owner Publications in Service Publications Ordering 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.

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.

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.

You must close all doors and the trunk before reconnecting the battery. After reconnecting the battery, you must press the unlock button on the key transmitter. Failure to follow this procedure may result in a sounding alarm. Pressing unlock on the key transmitter would stop the sounding alarm.
