fuse.
Always use genuine Lexus fuses, or equivalent. Do not use copper wire or other
objects, even as a temporary measure.
Do not modify the fuse or the fuse box.

Maintenance and care
If there is an overload in the circuits from the battery
The fuses are designed to blow before the wiring harness is damaged.
CAUTION
When replacing fuses
Always use a genuine Lexus fuse or equivalent.
Never install an ordinary wire - even as a temporary fix.
This may cause extensive damage and possibly a fire.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by your Lexus
dealer.
