Battery
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. See Engine Compartment Overview on page 366 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.
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.
CAUTION:
Batteries have acid that can burn you and
gas that can explode. You can be badly
hurt if you are not careful.
