WHAT TO DO IN EMERGENCIES 243 1. Attach one end of the jumper cable to the positive terminal of the discharged battery and the other end of the same cable to the positive terminal of the booster battery. WARNING! • Do not connect the cable to the negative terminal of the discharged battery. The resulting electrical spark could cause the battery to explode. • During cold weather when temperatures are below freezing point, electrolyte in a discharged battery may freeze. Do not attempt jump starting because the battery could rupture or explode. The battery temperature must be brought up above freezing point before attempting to jump start. 3. Take care that the clamps from one cable do not touch clamps from the other cable. Do not lean over the battery when making the connection. The negative connection must provide good electrical conductivity and current carrying capacity. WARNING! Do not permit vehicles to touch each other as this could establish a ground connection and personal injury could result. 2. Connect one end of the other jumper cable to the negative terminal of the booster battery. Connect the other end of the jumper cable to a good ground on the vehicle with the discharged battery. Make sure a good connection is made, free of dirt and grease. 6
