Question 3 of 6:
How do you reset a Prius hybrid check?
-
Try pulling over and turning the car off for a few minutes to reset it. If the hybrid check light comes on while you’re driving, pull over somewhere safe. Turn off your car and let it sit for 5-10 minutes. Then, try starting it back up again to reset it. If the light turns off, it may have been a system error and there isn’t anything wrong with your car. However, if the light stays on, there may be a problem with your Prius.

Check for blown fuses that could be causing the issue. If your hybrid check light stays on even after you reset it, look at your car’s fuses to see if any of them are blown. Check beneath your hood or dashboard for the fuse box. Look for broken filaments or discoloration. Replace any blown fuses with new ones of the same type and see if that fixes the issue.

Question 5 of 6:
Why is my Prius not turning on?
-
Usually, it’s the alternator, starter, or battery. These are the most common reasons why your Prius won’t start or turn on. Fixing the problem can involve replacing the part, cleaning the connections, or making repairs to the system. Because there are many potential causes, it’s important that you get a full diagnosis from a licensed technician at an auto repair shop. [9] X Research source
-
You may have overfilled the engine oil. The Prius owner’s manual is super helpful and tells you exactly what type of oil your car needs. But because your Prius is so sensitive to how much engine oil is in it, if you overfill the tank, your car won’t start. It’s a fail-safe measure that keeps your car’s engine from getting damaged. If there aren’t any other issues with your Prius, it could be the oil. Try draining and refilling your car’s oil or have a licensed mechanic change your oil. [10] X Research source
