Battery; Jump Starting; Vehicle Storage - GMC 2004 Yukon XL Owner's Manual

Battery

Your new vehicle comes with a maintenance free
®
ACDelco 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
battery. See Engine Compartment Overview on
page 5-14 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.
