Maintenance and care
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. 538)
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 vehi-
cle. Because certain bulbs are connected to circuits designed to prevent overload,
non-genuine parts or parts not designed for this vehicle may be unusable.
WA R N I N G
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 autho-
rized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional as soon as possible.
