    This light illuminates when there is a problem with the vehicle’s hybrid system. The Prius is equipped with a hybrid system consisting of a battery-powered electric motor and a gasoline-powered internal combustion engine, the two working together. When the “Check Hybrid System” light comes on, it means that the vehicle’s warning system has detected a problem. It could be something as minor as a broken fuse, or something more serious like a faulty alternator. [1] X Research Source

    • Sometimes, the system says there is an error when there is really no error. If this is the case, you just need to restart the car and the error will be gone.

    You should not ignore this warning light. Although you can still drive when the indicator light is on, damage to the vehicle can become more serious. If the light does not go out after you have restarted the vehicle, you should call an ambulance or drive yourself to the repair shop as soon as possible. If there is a problem with the vehicle, finding it early will save time and money in the long run. [2] X Research Source

    Pull over to the side of the road and turn off the engine for a few minutes to clear the error message. If the hybrid indicator light comes on while the vehicle is moving, you should steer the vehicle to the side of the road. Turn off the engine and wait 5-10 minutes. Then reboot to clear the error message. If the light doesn’t come on then it could be a system fault and nothing is wrong with the vehicle. However, if the lights are still on, the car may have a problem. [3] X Research Sources

    Check the fuse as that could be the cause. If the hybrid check light remains on after you’ve restarted the vehicle, look for a blown fuse. Check under the bonnet or dashboard for the fuse box. Look for small fibers or discoloration. Replace the burned fuse with a new fuse of the same type and see if that fixes the problem. [4] X Research Sources

    • Diagnostic testing usually costs about $120 in the US.

    The cause is usually in the generator, starter, or battery. These are the most common reasons why your Prius won’t start. The repair can be done by replacing, cleaning the connection, or repairing. Since there are many potential causes, it is important that you bring your vehicle to a repair shop for a comprehensive diagnosis. [11] X Research Source

    You may have over-oiled the engine. The user manual is very helpful and shows what type of oil the car uses. But because the Prius is very sensitive to engine oil, if you add too much, it won’t start. It is a measure to prevent the car engine from being damaged. If the car has no problems, the cause may be engine oil. Try draining the oil and refilling it or have a mechanic change the engine oil. [12] X Research Source
