■ 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. 455)
● 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.
■ 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.
