Place your right foot firmly on the brake before attempting to start the car.
In most newer Prius models, you need only to have the smart key in the cabin of the vehicle. In older Prius models, place the key into the ignition hole with the fob’s button side facing towards the roof of the car without turning the key.
If you do not hear a beep, press the button again for a bit longer. The electric motor will start, but the gasoline one may not until it needs to.
The word “ready” will appear on the screen to indicate that the Prius is ready to be driven. Take the vehicle out of park and put it into drive to begin driving.
Be sure the floor mat hasn’t gotten bunched up beneath the pedal. Check for any other obstructions that may prevent you from pushing the brake pedal down.
If this method works, you should have the battery replaced in your smart key as soon as possible.
Check in the owner’s manual for your specific model of Prius to see if it came equipped with a smart key deactivation switch.
If the smart key deactivation switch was pressed before, hitting it again will reactivate the smart key sensor. Attempt to start the car again once you’ve hit the switch.
The fuse box is located on the driver’s side near the headlight at the front of the engine bay. It is housed beneath a black, plastic cover.
Be sure not to damage the clips as you release them. The terminal in the fuse box is marked with a positive (+) symbol and is surrounded by red plastic.
Be sure the jumper cable has a strong connection to the positive terminal in the fuse box.
Connect the other end of the black cable to the negative terminal on the other vehicle’s battery. Be careful, once both cables are connected to the other vehicle’s battery, touching the two ends of the cables will create sparks.
Leave the other vehicle connected to the Prius until you get it to start. Make sure the connections are secure if the charge doesn’t seem to be working.
