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. 534)
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-genuine parts or parts not designed for this vehicle may be
unusable.

CAUTION
To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage, 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.
This can cause extensive damage or even fire.
Do not modify the fuses or fuse boxes.
Fuse box near the power control unit
Never check or replace the fuses as there are high voltage parts and wiring
near the fuse box.
Doing so may cause electric shock, resulting in death or serious injury.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional as soon as possible.
