Urgently EV Best Practices

Battery Access

  1. The discharged battery positive (+) terminal and the discharged battery negative (–) grounding point are under a cover. Remove the cover to expose the terminal.
  2. Check the other vehicle. It must have a 12-volt battery with a negative ground system.
  3. Get the vehicles close enough so the jumper cables can reach, but make sure the vehicles are not touching each other.
  4. To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the jump start procedure. Put the vehicles into P (Park). If the other vehicle has a manual transmission, put the vehicle in N (Neutral) before setting the parking brakes.
  5. Turn off both vehicles. Unplug unnecessary accessories plugged into the cigarette lighter or the accessory power outlet. Turn off the radio and all lamps that are not needed.
  6. Open the hood.
  7. To open the lid, pull the handle to disengage the clips and remove the cover.
  8. Remove the covers of the positive and negative terminals.
  9. Locate the battery positive (+) terminal and negative (−) grounding point.
  10. Check that the jumper cables do not have loose or missing insulation.
  11. Connect one end of the red positive (+) cable to the discharged battery positive (+) terminal. Do not let the other end touch metal.
  12. Connect the other end of the red positive (+) cable to the good battery positive (+) terminal.
  13. Connect one end of the black negative (−) cable to the good battery negative (−) terminal. (Do not let the other end touch anything until the next step.)
  14. Connect the other end of the negative (−) cable to the discharged battery negative (−) grounding point.
  15. Now start the vehicle with the good battery and keep the vehicle running for a while.
  16. Try to start the vehicle that had the dead battery. If it will not start after a few tries, it probably needs service.

WARNING: Battery posts, terminals and related accessories can expose you to chemicals including lead and lead compounds, which are known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling. For more information go to www.P65Warnings.ca.gov.

Batteries can hurt you. They can be dangerous because:

• They contain acid that can burn you.

• They contain gas that can explode or ignite.

• They contain enough electricity to burn you.

Use eye protection when handling the battery. If you do not follow these steps exactly, some or all of these things can hurt you.

Charging the 12-volt battery and the high voltage battery at the same time may result in overheating or failure. Do not attempt to charge the 12-volt battery and the high voltage battery at the same time. If jumpstarting fails, see your dealer for service.

Always inspect jumper cables prior to use. Jumper cables with loose or missing insulation could shock you or cause vehicle damage. Do not use jumper cables that appear damaged.

CAUTION: The vehicle is equipped with an AGM/VRLA 12-volt battery, which can be damaged by using the incorrect type of trickle charger. An AGM/VRLA-compatible charger must be used, with the appropriate setting selected. Follow the trickle charger manufacturer instructions.

Ignoring these steps could result in costly damage to the vehicle that would not be covered by the vehicle warranty. Trying to start the vehicle by pushing or pulling it will not work, and it could damage the vehicle.

If the jumper cables are connected or removed in the wrong order, electrical shorting may occur and damage the vehicle. The repairs would not be covered by the vehicle warranty. Always connect and remove the jumper cables in the correct order, making sure that the cables do not touch each other or other metal.

If the other vehicle does not have a 12volt system with a negative ground, both vehicles can be damaged. Only use a vehicle that has a 12-volt system with a negative ground for jump starting.

If the vehicles touch each other while jump starting, a ground connection may occur that disables your vehicle and/or damages the electrical systems of one or both vehicles.  

If any accessories are left on or plugged in during the jump starting procedure, they could be damaged. The repairs would not be covered by the vehicle warranty. Whenever possible, turn off or unplug all accessories on either vehicle when jump starting.

If the other vehicle does not have a 12volt system with a negative ground, both vehicles can be damaged. Only use a vehicle that has a 12-volt system with a negative ground for jump starting.

If the vehicles touch each other while jump starting, a ground connection may occur that disables your vehicle and/or damages the electrical systems of one or both vehicles.  

If any accessories are left on or plugged in during the jump starting procedure, they could be damaged. The repairs would not be covered by the vehicle warranty. Whenever possible, turn off or unplug all accessories on either vehicle when jump starting.
