After a fuse is replaced

●

If the lights do not turn on even after the fuse has been replaced, a bulb may need

replacement. (

P. 432)

●

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.

■

When replacing light bulbs
Lexus recommends that you use genuine Lexus products designed for this vehicle.

Because certain bulbs are connected to circuits designed to prevent overload, non-gen-

uine parts or parts not designed for this vehicle may be unusable.

WARNING

■

To prevent system breakdowns and vehicle fire
Observe the following precautions.

Failure to do so may cause damage to the vehicle, 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.

●

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.
