4-3. Do-it-yourself maintenance
nAfter a fuse is replaced
lIf the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. (→P. 511)
lIf the replaced fuse blows again, have the vehicle inspected by your Lexus
dealer.
nIf there is an overload in the circuit
The fuses are designed to blow, protecting the wiring harness from damage.
CAUTION
nTo prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing to do so may cause damage, and possibly a fire or injury.
lNever use a fuse of a higher amperage rating than indicated, or use any other
object in place of a fuse.
lAlways 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.
lDo not modify fuse or fuse boxes.
NOTICE
nBefore replacing fuses
Have the cause of electrical overload determined and repaired by your Lexus
dealer.
