■
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 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
Lexus products designed for this vehicle.
Because certain bulbs are connected to cir-
cuits designed to prevent overload,
non-genuine parts or parts not designed for
this vehicle may be unusable.

WARNING
■ 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 your Lexus
dealer as soon as possible.
