■After a fuse is replaced
●If the lights do n ot turn on even
after the fuse has been replaced,
a bulb may need replacement.
(  P.415)
●If the replaced fuse blows again,
have the vehicle inspected by
your Toyota dealer.
■If there is an overload in a cir-
cuit
The fuses are designed to blow, pro-
tecting the wiring harness from
damage.
■When replacing light bulbs
Toyota recommends that you use
genuine Toyota pr oducts designed
for this vehicle. Because certain
bulbs are connected to circuits
designed to prevent overload,
non-genuine parts or parts not
designed for this vehicle may be
unusable.
WARNING
■To prevent system break-
downs and vehicle fire
Observe the following precau-
tions.
Failure to do so may cause dam-
age to the vehicle, and possibly a
fire or injury.
●Never use a fuse of a higher
amperage rating than that indi-
cated, 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 over-
load determined and repaired by
your Toyota dealer as soon as
