After a fuse is replaced

If there is an overload in the 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.

Failing 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.
  • Always use a genuine Toyota fuse or equivalent.

    Never replace a fuse with a wire, even as a temporary fix.

  • Do not modify the fuses or fuse boxes.

NOTICE

Before replacing fuses

Have the cause of electrical overload determined and repaired by your Toyota dealer as soon as possible.
