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. 343)
If the replaced fuse blows again, have the vehicle inspected by any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.
CAUTION
To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing 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 indicated, or use any
other object in place of a fuse.
Always use a genuine Toyota fuse or equivalent.
Do not modify the fuse or the fuse box.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
