NOTICE
Pop Up Hood precautions
Make sure to close the hood before driving, as the system may not operate
properly if the hood is not fully closed.
Make sure that all 4 tires are of the specified size and inflated to the specified
tire pressure (P. 570). If tires of a different size are used, the system may
not operate properly.
If something has hit the area around the front bumper, the sensors may be
damaged even if the Pop Up Hood has not operated. Have the vehicle
inspected by any authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional.
Do not remove or repair the parts or wiring of the Pop Up Hood, as doing so
may cause accidental operation or prevent the system from operating prop-
erly. If repair or replacement is necessary, contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Do not remove such components as the front bumper, hood or suspension, or
replace them with non-genuine parts, as doing so may prevent the system
from operating properly.
Do not install anything to the front bumper or hood, as doing so may prevent
the sensors from detecting an impact correctly and prevent the system from
operating properly.
Do not close the hood with force or apply load to the lifters, as doing so may
damage the lifters and prevent the system from operating properly.
Do not modify the suspension, as changes made to the vehicle height may
prevent the system from operating properly.

Maintenance and care
IS300h_EE(OM53B95E)
Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle’s interior.
Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or
brush to apply the foam. Rub in overlapping circles. Do not use water. Wipe dirty
surfaces and let them dry. Excellent results are obtained by keeping the carpet as
dry as possible.
Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check
the belts periodically for excessive wear, fraying or cuts.
When cleaning the carpeted portions of the glove box, console box, etc.
If a strong adhesive tape is used, there is a possibility that the surface of the car-
pet could be damaged.
CAUTION
Water in the vehicle
Do not splash or spill liquid in the vehicle, such as on the floor, in the hybrid
battery (traction battery) air vents, and in the trunk.
Doing so may cause the hybrid battery, electrical components, etc. to mal-
function or catch fire.
Do not get any of the SRS components or wiring in the vehicle interior wet.
(P. 4 4 )
An electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or serious injury.
Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect off
the windshield, obstructing the driver’s view and leading to an accident, result-
ing in death or serious injury.

4787-3. Do-it-yourself maintenance
IS300h_EE(OM53B95E)
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. 479)
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.
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 autho-
rized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional as soon as possible.
