EMERGENCY - How to Jump Start a Battery any other metal on the vehicle at the same time. Remove metal jewelry and avoid leaning over the battery. 1. Remove any personal jewelry that may come in contact with the battery terminals. 2. Select a jumper cable that is long enough to attach to both vehicles in a way that ensures neither vehicle touches each other. 3. Position the two vehicles together, but do not allow them to touch. 4. Turn OFF all lights, heater, radio, and any other accessory on both vehicles. 5. Set the parking brakes: pull out the Yellow button located on the dash. See Air Brake System on page 146. 6.
Shift the transmission into park position or neutral for manual transmissions. See Operating Manual Transmissions on page 141 and see Automatic and Automated Transmissions on page 143. 7. If either vehicle is equipped with battery disconnects ensure they are in the OFF position prior to connecting the two vehicles. 8. Attach one end of a jumper cable to the positive (+) terminal of the discharged (dead) battery. This will have a large red + or P on the battery case, post, or clamp. CAUTION Applying a higher voltage booster bat- tery will cause expensive damage to sensitive electronic components, such as relays, and the radio. Failure to comply may result in equipment dam- age.
2 NOTE Always connect positive (+) to positive (+) and negative (-) to negative (-). CAUTION 9. Attach the other end of the same cable to the positive (+) terminal of the good (booster) battery. 10. Attach the remaining jumper cable FIRST to the negative (-) terminal (black or N) of the good battery. 11. Attach the other end of the negative cable to the negative (-) terminal (black or N) of the dead battery. 12. If either vehicle is equipped with battery disconnects, ensure that they are in the ON position. 13. Start the vehicle that has the good battery first. Let it run for 5 minutes. 14. Start the vehicle that has the discharged (dead) battery. The engine should start.
If the engine fails to start, do not continue to crank the Improper hook-up of jumper cables or not following these procedures can damage the alternator or cause seri- ous damage to both vehicles. WARNING Heed all warnings and instructions of the jumper cable manufacturer. Failure to comply may result in death, person- al injury, equipment or property dam- age. Be careful that metal tools (or any metal in contact with the positive terminal) do not contact the positive battery terminal and Y53-6047-2HEN (03/18) 47
