yellowblue CAUTION: 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 don't need to add water to the ACDelco FreedomR battery installed in every new GM 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. Don't 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. 5. Find the positive (+) and negative (-) terminals on each battery. Your vehicle has a remote positive (+) jump starting terminal. The terminal is on the same side of the engine compartment as your battery. You should always use the remote positive (+) terminal instead of the positive (+) terminal on your battery. To uncover the remote positive (+) terminal, lift the red plastic cap. 5-5
