CAUTION: (Continued)
Be sure the batteries have enough water.
You do not need to add water to the
®
ACDelco battery (or batteries) installed in
your new vehicle. But if a battery has filler
caps, be sure the right amount of fluid is
there. If it is low, add water to take care of
that first. If you do not, explosive gas
could be present.
Battery fluid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, flush the place with water and get
medical help immediately.
