Jump-starting The Car
If a dead battery is the cause behind your Prius failing to start, jump-starting the car might be just what you need. It’s a simple and quick method that will provide your vehicle with an immediate boost of power. Follow these steps:
- Park another vehicle with a functioning battery close to your Prius, ensuring the two cars don’t touch.
- Open the hood of both cars, locate the batteries, and identify the positive and negative terminals using the (+) and (-) signs.
- With jumper cables in hand, start by connecting the positive or red cable to the positive terminal of the dead battery.
- Now, attach the other end of the positive cable to the positive terminal of the fully charged battery.
- Next, connect the negative or black cable to the negative terminal of the fully charged battery.
- Finally, connect the remaining end of the negative cable to an unpainted metal surface in your Prius, away from the battery.
- Once properly connected, start the car with the functioning battery and allow it to idle for a few minutes.
- Try starting your Prius. If successful, keep it running for a while before disconnecting the cables.
- Remove the cables in the reverse order of how they were connected and ensure they don’t touch each other during removal.
Replacing The 12-volt Battery
If jump-starting your car doesn’t resolve the issue, it might be time to replace the 12-volt battery. Over time, these batteries can deteriorate and lose their ability to hold a charge effectively. Follow these steps to ensure a smooth battery replacement process:
