■After a fuse is replaced
●When installing the lid, make sure
that the tab is installed securely.
●If the lights do n ot turn on even
after the fuse has been replaced,
a bulb may need replacement.
●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 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
possible.
