Checking and replacing fuses
Turn the power switch off.
After a system failure, see “Fuse layout and amperage ratings”
for details about which fuse to check. (P. 787)
Open the fuse box cover.
Engine compartment:
Remove the engine compart-
ment cover (P. 740) and
remove all of the clips.
Push the tabs on either side to
detach the lock and lift the lid

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. 803)
If the replaced fuse blows again, have the vehicle inspected by any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
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-genuine 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.
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.
