■ After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacing. ( P. 336)
● If the replaced fuse blows again, have the vehicle inspected by your
Toyota dealer.
■ If there is an overload in the circuits
The fuses are designed to blow before the entire wiring harness is damaged.
