Vehicle Care 9-79 { WARNING Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. 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 don't, 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. { WARNING Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running. 6. Do not let the other end of the red positive (+) cable touch metal.
