■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. 565)
● 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, 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.
This can cause extensive damage or even fire.
● 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.
