2022 Toyota Prius Fuses and Fuse Box | How to change fuse
Inside the 2022 Toyota Prius, there is a complex electrical system that uses fuses to protect different parts from electrical spikes or problems. These fuses are kept in a special fuse box inside the car. The fuse box is where all of the car’s fuses are kept together. Each fuse is meant to protect a different electrical system. If there is an electrical problem, a blown fuse could be to blame. Prius owners should know how to find and repair in this situation. Finding and changing a fuse in a 2022 Prius is a pretty simple task. Starting point: look in the car’s instructions to find the exact fuse that is connected to the broken part. Once you know where the fuse box is, which is usually in the engine bay or the cabin, carefully remove the bad fuse using the fuse puller or a pair of pliers. Put in a new fuse with the same amperage number to make sure it fits securely. This easy step-by-step guide helps Prius users fix electrical problems quickly and keep the car running at its best. When working with fuses, you should always be careful and follow the safety rules in the car’s instructions.

If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this vehicle. Because certain bulbs are connected to circuits designed to prevent overload, non-genuine parts or parts not designed for this vehicle may be unusable.
WARNING
To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or injury.
- Never use a fuse of a higher amperage rating than that indicated, or use any other object in place of a fuse.
