After a fuse is replaced

• If the lights do not 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 overload in the circuit

The fuses are designed to blow, protecting the wiring harness from damage.

When replacing light bulbs

Toyota recommends that you use genuine Toyota products 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.
