Vehicle Care 5. Check that the jumper cables do not have loose or missing insulation. If they do, you could get a shock. The vehicles could be damaged too. Before you connect the cables, here are some basic things you should know. Positive (+) will go to positive (+) or to a remote positive (+) terminal if equipped. Negative (−) will go to an unpainted metal part or to a remote negative (−) terminal if equipped. Do not connect positive (+) to negative (−) or you will get a short that would damage the battery and possibly other parts too. Do not connect the negative (−) cable to the negative (−) terminal on the dead battery because this can cause sparks. 6. Connect the red positive (+) cable to the positive (+) terminal (1) of the dead battery. Use a remote positive (+) terminal if equipped. Do not let the other end touch metal. Connect it to the positive (+) terminal (4) of the good battery. Use a remote positive (+) terminal if equipped. 7. Connect the black negative (−) cable to the negative (−) terminal (3) of the good battery. Use a remote negative (−) terminal if equipped. 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 the shock tower, or to a remote negative (−) terminal on the vehicle with the dead battery. 8. Connect the other end of the negative (−) cable to the negative (−) grounding point (2) on the shock tower of the vehicle with the dead battery. 10-57 { Caution Make sure the jumper cables do not touch moving parts in the engine compartment and that the cable clamps do not contact any other metal. 9.
