Battery - GMC T-Series 2007 Owner's Manual

Battery

Your vehicle has two 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
If you are not going to drive your vehicle for
25 days or more, remove the black, negative (−)
cable from each battery. This will help keep
the batteries 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 on page 236 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.
