FAQs—Toyota Prius C
The MPG meter of my Toyota Prius C is showing numbers that are way higher than its normal gas mileage. Is this normal? What should I do?
Tests have shown that MPG meters actually tend to skew highly in its measurements. However, if you noticed that your Toyota Prius C's meter reads more unbelievably than it usually does, then there might be something wrong with one of your car's components. The tires might be underinflated, your vehicle might be poorly maintained or overloaded, or you might be running the air conditioning for too long. Observe the readings for a few more days to make sure it isn't a one-time thing. During this time, try to save as much power as you could to check if these will affect the readings. If the meter is still reading unbelievable measurements, then you will have to take your car to a dealer and have them troubleshoot then repair or replace it.
The air conditioner and fan of my Toyota Prius C will not turn on. How do I diagnose the problem?
The first thing you should do is check for any blown fuse and replace any that you find. If they all seem to be in order, inspect the off button of the fan and see if it's stuck. This is a common problem for the Toyota Prius C, and if this is the case for your car, simply wiggle it loose. However, if the off button is working fine, then you will need a code reader to diagnose any possible problems or take your car to a dealer.
When I start my Toyota Prius C, all of the electronics will turn on except for the "Ready" sign on the screen, which usually shows up after the car starts. This doesn't happen all the time. However, when it does, I also notice that the LED light on the power button turns from green to orange/red when I step off the brake. This will keep going on until I turn off and restart my car and the "Ready" sign finally shows on the screen. What's going on with my car?
This may be due to a malfunctioning stop light switch or a weak battery. If the "Ready" sign doesn't show up again even after so many tries, you can try to do the emergency hybrid control system start procedure. First, push the P position switch. Then, while making sure that the parking brake pedal is depressed, turn on the power switch. Next, keep your foot off the brake pedal then press and hold the power switch for 15 to 20 seconds. If this works and the "Ready" sign is on the screen upon starting, then this confirms that the stop light switch needs to be checked. Otherwise, try jumpstarting the battery and get it checked or replaced.
My Toyota Prius C's engine stalled right after the hybrid motor warning light appeared. What's going on and how can I fix it?
It is possible that your Toyota Prius C experienced a loss of power and total failure because of a defective electrical panel. You will have to take it to your dealer and get the entire hybrid inverter motor component replaced.
