9. Connect the other end of the negative (−) cable at least 18 inches (45 cm) away from the dead battery, but not near engine parts that move. The electrical connection is just as good there, and the chance of sparks getting back to the battery is much less. 10. Now start the vehicle with the good battery and run the engine for a while. 8. Now connect the black negative (−) cable to the negative (−) terminal of the good battery. Use a remote negative (−) terminal if the vehicle has one. Do not let the other end touch anything until the next step. The other end of the negative (−) cable does not go to the dead battery. It goes to a heavy, unpainted metal engine part or to a remote negative (−) terminal on the vehicle with the dead battery. Notice: If the jumper cables are removed too quickly after starting the vehicle with the dead battery, a momentary spike in voltage may occur, damaging electrical components. The repairs would not be covered by your warranty. Always allow both vehicles involved in the jump start procedure to run for at least one minute after starting the vehicle with the dead battery, before removing the jumper cables. 11. Try to start the vehicle that had the dead battery. If it will not start after a few tries, it probably needs service. If the vehicle does start, be sure to allow both vehicles to run for at least one minute before removing the jumper cables. 5-41
