WHAT TO DO IN EMERGENCIES 399 WARNING! • Battery fluid is a corrosive acid solution; do not allow battery fluid to contact eyes, skin or clothing. Do not lean over a battery when attaching clamps or allow the clamps to touch each other. If acid splashes in eyes or on skin, flush contaminated area immediately with large quantities of water. • A battery generates hydrogen gas which is flammable and explosive. Keep flame or spark away from the vent holes. • Do not use a booster battery or any other booster source that has a greater than 12-Volt system, i.e. Do not use a 24-Volt power source. 1. Remove all metal jewelry such as watch bands or bracelets, which might make an unintended electrical contact. 2. Park the booster vehicle within cable reach but without letting the vehicles touch. Set the parking brake on both vehicles, place the transmission in PARK, and turn the ignition OFF. 3. Turn off the heater, radio, and all unnecessary electrical loads. 4. Connect one end of a jumper cable to the positive terminal of the booster battery. Connect the other end of the same cable to the positive terminal of the discharged battery. 6 WARNING! Do not permit vehicles to touch each other as this could establish a ground connection, and personal injury could result.
