may need replacement.
●If the replaced fuse blows again, have the vehicle inspected by your Toyota dealer.
■If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.

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.

Never replace a fuse with a wire, even as a temporary fix.
●Do not modify the fuses or fuse boxes.
