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 the circuit
The fuses are designed to blow before the entire wiring harness is damaged.
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.
NOTICE:
Before replacing fuses
Have the cause of electrical overload determined and repaired by your Lexus
dealer as soon as possible.
