■After a fuse is replaced

  • If the lights do not turn on even after the fuse has been replaced, a bulb 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.


■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.
