Maintenance and care
Normal fuse
Blown fuse
■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.443)
●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 products 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.
WA R N I N G
■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.
■Fuse box near the power con-
trol unit
Never check or replace the fuses
as there are high voltage parts
and wiring near the fuse box.
Doing so may cause electric
shock, resulting in death or seri-
ous injury.
NOTICE
■Before replacing fuses
Have the cause of electrical over-
load determined and repaired by
your Toyota dealer as soon as
possible.
