■ 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. 251)
● If the replaced fuse blows again, have the vehicle inspected by your
Scion dealer.
■ If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.

If the bulb is scratched or dropped it may blow out or crack.
● Fully install light bulbs and any parts used to secure them. Failing to do so
may result in heat damage, fire, or water entering the headlight unit. This
may damage the headlights or cause condensation to build up on the lens.
■ To prevent damage or fire
Make sure bulbs are fully seated and locked.
