■After a fuse is replaced
●When installing the lid, make sure that the tab is installed securely.
●If the lights do not turn on even after the fuse has been replaced, a bulb may need replacement. ( P.355)
●If the replaced fuse blows again, have the
vehicle inspected by any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
■If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.

vehicle may be unusable.
