If your 42-volt battery has run down, you may want to use another vehicle's 12-volt battery and jumper cables to start your vehicle. Jump starting your hybrid vehicle may take considerably longer than a regular vehicle. You may have to wait 10 to 20 minutes total for your vehicle to charge from the other vehicle's good 12-volt battery in order to start your vehicle. Use the following steps to do it safely:

Caution: Batteries can hurt you. They can be dangerous because:

Notice: Ignoring these steps could result in costly damage to the vehicle that would not be covered by the warranty.

1. Check to see that the battery disconnect switch on your hybrid vehicle is in the power position. If it is not, turn it clockwise until it stops and then try to start your vehicle. See Battery Disconnect Switch for more information. If your vehicle still won't start, continue to Step 2.
2. Check the other vehicle. It must have a 12-volt battery with a negative ground system.

Notice: If the other vehicle's system is not a 12-volt system with a negative ground, both vehicles can be damaged. Only use vehicles with 12-volt systems with negative grounds to jump start your vehicle.

3. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not touching each other. If they are, it could cause a ground connection you do not want. You would not be able to start your vehicle, and the bad grounding could damage the electrical systems.

To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the jump start procedure. Put an automatic transmission in PARK (P) or a manual transmission in NEUTRAL before setting the parking brake.

Notice: If you leave the radio or other accessories on during the jump starting procedure, they could be damaged. The repairs would not be covered by the warranty. Always turn off the radio and other accessories when jump starting the vehicle.

4. Turn off the ignition on both vehicles. Unplug unnecessary accessories plugged into the cigarette lighter and accessory power outlets. Turn off the radio and all lamps that are not needed. This will avoid sparks and help save both batteries. And it could save your radio!
5. Open the hoods and locate the positive (+) and negative (-) terminal locations of the other vehicle.

Your vehicle has a remote positive (+) 12-volt jump starting terminal and a remote negative (-) jump starting terminal. You should always use these remote terminals instead of the terminals on the battery.




6. The remote positive (+) terminal is located under a red plastic cover near the center of the engine compartment. See Engine Compartment Overview . To access the remote positive (+) terminal, open the red plastic cover.



7. The remote negative (-) terminal is located on the engine accessory drive bracket behind the power steering pump and is marked GND. Do not connect the jumper cables to any part of the power steering pump or hoses.

See Engine Compartment Overview for more information on location of the positive (+) and negative (-) terminals.

Caution: Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light.

Be sure the battery has enough water. You do not need to add water to the battery installed in your new vehicle. But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to take care of that first. If you do not, explosive gas could be present.
Battery fluid contains acid that can burn you. Do not get it on you. If you accidentally get it in your eyes or on your skin, flush the place with water and get medical help immediately.

Caution: An electric fan can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan.

Caution: Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running.

8. 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 to the other vehicle, here are some basic things you should know. Positive (+) will go to positive (+) or to a remote positive terminal (+) if the vehicle has one. Negative (-) will go to a heavy, unpainted metal engine part or to a remote negative (-) terminal, if the vehicle has one.

Do not connect positive (+) to negative (-) or you will get a short that would damage the battery and maybe other parts too.




9. Connect the red positive (+) cable to the remote positive (+) terminal of your hybrid vehicle.
10. Do not let the other end touch metal. Connect it to the positive (+) terminal of the good battery. Use a remote positive (+) terminal if the other vehicle has one.
11. Now connect the black negative (-) cable to the negative (-) terminal of the good battery. Use a remote negative (-) terminal if the vehicle has one.



12. Do not let the other end touch anything until the next step. The other end of the negative (-) cable doesn't go to the dead battery. It goes to your vehicle's remote negative (-) terminal, marked GND. The electrical connection is just as good there, and the chance of sparks getting back to the battery is much less.
13. Now start the vehicle with the good battery.
14. Try to start the hybrid vehicle. Hold the key in the start position for at least three seconds. If the hybrid vehicle still does not start, turn the key to LOCK and wait 5 minutes.
15. After 5 minutes try to start the hybrid vehicle again.
16. Repeat steps 11 and 12 several more times as necessary. If the hybrid vehicle still will not start, your vehicle needs service.

Notice: 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.

3. Remote Positive (+) Terminal on hybrid vehicle.

To disconnect the jumper cables from both vehicles do the following:

1. Disconnect the black negative (-) cable from the hybrid vehicle.
2. Disconnect the black negative (-) cable from the vehicle with the good battery.
3. Disconnect the red positive (+) cable from the vehicle with the good battery.
4. Disconnect the red positive (+) cable from the hybrid vehicle.
5. Return the positive (+) remote terminal cover on your hybrid vehicle to its original position.
