■ After a fuse is replaced

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

need replacement. (P. 359)

● If the replaced fuse blows again, have the vehicle inspected by any autho-

rized Toyota dealer or repairer, or another duly qualified and equipped pro-

fessional.

■ If there is an overload in a circuit

The fuses are designed to blow, protecting the wiring harness from damage.

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.

●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 any

authorized Toyota dealer or repairer, or another duly qualified and equipped

professional as soon as possible.
