CAUTION: (Continued)
Be sure the battery has enough water.
You do not need to add water to the
battery 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.
