need replacement. (

If the replaced fuse blows again, have the vehicle inspected by your Lexus
dealer.
If there is an overload in the circuits
The fuses are designed to blow before the entire wiring harness is damaged.

4-3. Do-it-yourself maintenance
CAUTION
To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing to do so may cause damage, and possibly a fire or injury.
Never use a fuse of a higher amperage rating than 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 fuses or the fuse box.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by your Lexus
dealer.
