If your 12-volt battery discharges and your vehicle will not start, you can jump start your vehicle with a set of booster cables and a second vehicle.
Note: The 12-volt auxilliary battery is located under the hood in the front.
- Using the jumper cables, connect a red or a positive cable to your positive battery terminal. With the other end of the red cable, connect to the positive battery terminal of the second vehicle.
- Next, connect the black or negative cable to the second vehicle’s negative terminal. Connect the other end of the cable to a solid, stationary, unpainted metallic point, away from the 12-volt battery and any moving parts.
- Once you have all of the booster cables connected, start the engine of the second vehicle. Increase the engine speed slightly and maintain the level for about five minutes to recharge the Prius’ 12-volt battery.
- Then with your foot on the break, press the Prius power button to turn it on, and make sure the Ready indicator comes on.
- Once the Prius Ready light illuminates, remove the booster cables in the reverse order of how you connected them. Remove the black one attached to the Prius. Then the two from the second vehicle, and lastly the red one connected to the Prius’ 12-volt battery.
- After a jumpstart, it’s recommended that you have the vehicle inspected at your Toyota dealer.
