IS300h_EE(OM53D56E)
■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. 4 9 5 )
●If the replaced fuse blows again, have the vehicle inspected by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
■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.
CAUTION
■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.
■Fuse box near the power control unit
Never check or replace the fuses as there are high voltage parts and wiring near the
fuse box.
Doing so may cause electric shock, resulting in death or serious injury.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional as soon
as possible.
