Jump Starting








Jump Starting

Jump Starting the Sonata Hybrid is similar to conventional models. Specific methods and warnings are noted below.

1. Open the cover of 12V Auxiliary Battery in the trunk.

2. Make sure the booster battery is 12-volt and that its negative terminal is grounded.

3. If the booster battery is in another vehicle, do not allow the vehicles to touch.

4. Turn off all unnecessary electrical loads.

5. Connect the jumper cables in the exact sequence shown in the illustration. First connect one end of a jumper cable to the positive terminal of the discharged 12V Auxiliary Battery (1), Then connect the other end to the positive terminal on the booster battery (2). Connect one end of the other jumper cable to the negative terminal of the booster battery (3), Next, connect the other end to a solid, stationary, metallic point (such as, the trunk latch striker) away from the 12V Auxiliary Battery (4). Do not allow the jumper cables to contact anything except the correct battery terminals or the correct ground. Do not lean over the battery when making connections.

6. Start the engine of the vehicle with the booster battery and let it run at 2,000 rpm. Then start the engine of the vehicle with the discharged 12V Auxiliary Battery. Turn the ignition to "hybrid ready" and the LDC will recharge the 12V Auxiliary Battery. Note that the gasoline engine may start at any time when the ignition is in the ready position.
