■After a fuse is replaced
●When installing the lid, make sure
that the tab is ins talled securely.
●If the lights do not turn on even
after the fuse has been replaced,
a bulb may need replacement.
( P.435)
●If the replaced fuse blows again,
have the vehicle inspected by
your Toyota dealer.
■If there is an ove rload 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 con-
nected to circuits designed to pre-
vent overload, non-genuine parts of
parts not designed for this vehicle
may be unusable.

Never replace a fuse with a
wire, even as a temporary fix.
●Do not modify the fuses or fuse
boxes.
NOTICE

Have the cause of electrical over-
load determined and repaired by
your Toyota dealer as soon as
