Battery
Your new vehicle comes with one or more maintenance
free ACDelco
®
batteries. When it’s time for a new
battery, be sure it has the replacement number shown
on the original battery’s label. We recommend an
ACDelco
®
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’re 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
aren’t careful. See “Jump Starting” next 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.
Contact your dealer to learn how to prepare your
vehicle for longer storage periods.
Jump Starting
If your battery (or batteries) has run down, you may
want to use another vehicle and some jumper cables to
start your vehicle. Be sure to follow the steps below
to do it safely.

or all of these things can hurt you.
