■ 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.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.
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.
