In an Emergency 5. Connect the clearance lights, taillights, and signal lights. Also connect any special towing lights re- quired by local regulations. lated, deep-cycle batteries with jumper cables. Follow the manufacturer’s instructions when charg- ing deep-cycle batteries. Emergency Starting With Jumper Cables NOTE: On vehicles equipped with an optional jump-start post, attach the positive cable clamp to that post instead of to the battery. 1. Apply the parking brakes and turn off the lights and all other electrical loads. When using jumper cables, follow the instructions below. WARNING 2.
Connect an end of one jumper cable to the positive terminal of the booster battery, or jump-start post if equipped, and connect the other end of the cable to the positive terminal of the discharged battery, or jump-start post if equipped. See Fig. 10.2 . Batteries release explosive gas. Do not smoke when working around batteries. Put out all flames and re- move all sources of sparks or intense heat in the vicinity of the battery. Do not allow the vehicles to touch each other. Do not lean over the batteries when making connections, and keep all other per- sons away from the batteries.
Failure to follow these precautions could lead to severe personal in- jury as a result of an explosion or acid burns. WARNING Do the next step exactly as instructed and do not allow the clamps of one cable to touch the clamps of the other cable. Otherwise, a spark could occur near a battery, possibly resulting in severe personal injury from explosion and acid burns. CAUTION 3. Connect one end of the second jumper cable to the negative terminal of the booster battery, and con- nect the other end of the cable to a ground at least 12 inches (300 mm) away from the batteries of the Make sure both starting systems have the same voltage outputs, and avoid making sparks.
Other- wise the vehicle charging systems could be se- verely damaged. Also, do not attempt to charge iso- 10.3
