■After a fuse is replaced
●If the lights do not turn on even after the fuse has been repla ced, a bulb may
need replacement. ( P. 563)
● If the replaced fuse blows again, have the vehicle inspected by your Toyota
dealer.
■ If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness f rom damage.

overload, non-genuine parts or parts not designed for this vehicle may be
unusable.

Never replace a fuse with a wire, even as a temporary fix.
