■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 5 8 )
●If the replaced fuse blows again, have the vehicle inspected by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
■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 Lexus products designed for this vehicle.
Because certain bulbs are connected to circuits designed to prevent overload, non-gen-
uine parts or parts not designed for this vehicle may be unusable.
WA R N I N G
■To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or injury.
●Never use a fuse of a higher amperage rating than that indicated, or use any other
object in place of a fuse.
●Always use a genuine Lexus fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
●Do not modify the fuses or fuse boxes.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional as soon
as possible.
