■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. 392)

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

rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.

■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.

7

●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 retailer or Toyota authorized repairer, or any reliable

repairer as soon as possible.
