• 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.
