Although its not a common problem, very cold weather can drain the batteries of a Toyota Prius and the only way to make it run again is to jump-start it.
All you need is a pair of jump start cables and another functional car or an auxiliary starting unit (you know, that huge battery used in services to start a dead car) if you happen to have one. Here’s how to do it:
- Open the vehicle’s hood and locate the fuse box. It should be at the far right as you are looking at the engine bay
- Remove the fuse box plastic cover to expose the fuses
- Locate the red cap with the plus sign and take it off to reveal the metal terminal
- Connect the positive (red) cable to the metal terminal in the fuse box and the negative (black) one to a mass bolt on the car’s body/engine bay
- Connect the other ends to the functional car’s battery - red to positive and black to negative
- Start the functional car and keep it a bit like that
- Go in the Prius and star it
- Let it idle a bit before turning it off, or go put some miles on it.
