■
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. 472)
● 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 writing harness is dam-
aged.
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 fuses or the fuse box.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by your
Toyota dealer.
