■After a fuse is replaced

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

may need replacing. (P. 357)

●If the replaced fuse blows again, have the vehicle inspected by your

Toyota dealer.

■If there is an overload in the circuits

The fuses are designed to blow before the entire wiring harness is damaged.

CAUTION

■To prevent system breakdowns and vehicle fire

Observe the following precautions.

Failing to do so may cause damage, and possibly a fire or injury.

●Never use a fuse of a higher amperage rating than 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.

This can cause extensive damage or even fire.

●Do not modify the fuse or the fuse box.

NOTICE

■Before replacing fuses

Have the cause of electrical overload determined and repaired by your

Toyota dealer, as soon as possible.
