■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. 365)
● 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.
