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.

CAUTION

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.

• 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.
