- 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.
- 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 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 as soon as possible.
