■After a fuse is replaced
●If the lights do not turn on even

●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 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.

blow out or crack.
●Fully install light bulbs and any
parts used to secure them. Fail-
ure to do so may result in heat
damage, fire, or water entering
the light unit. This may damage
the lights or cause condensa-

●Do not attempt t o repair or dis-
assemble light bulbs, connec-
tors, electric circuits or
component parts.
