■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. 4 3 2 )
●If the replaced fuse blows again, have the vehicle inspected by your Lexus dealer.
■If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
■When replacing light bulbs
Lexus recommends that you use genuine Le xus products designed for this vehicle.

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

NOTICE
■Before replacing fuses
Have the cause of electrical overload determ ined and repaired by your Lexus dealer as
