trically energized. To avoid death or seri-
ous injury, observe the following
precautions.
■When working on the engine com-
partment
●LC500h: Make sure that the “IGNI-
TION ON” on the multi-information
display and the “READY” indicator are
both off.
●Keep hands, clothi ng and tools away
from the moving fan and engine drive
belt.
ItemsParts and tools●LC500: Be careful not to touch the
engine, radiator, exhaust manifold, etc.
right after driving as they may be hot.
Oil and other fluids may also be hot.
LC500h: Be careful not to touch the
engine, power control unit, radiator,
exhaust manifold, etc. right after driv-
ing as they may be hot. Oil and other
fluids may also be hot.
●Do not leave anything that may burn
easily, such as paper and rags, in the
engine compartment.
●Do not smoke, cause sparks or expose
an open flame to fuel. Fuel fumes are
flammable.
■When working near the electric cool-
ing fan or radiator grille
Be sure the engine switch switch> is off.
With the engine switch in
IGNITION ON mode , the
electric cooling fan may automatically
start to run if the air conditioning is on
and/or the coolant temperature is high.
(  P.309)
■Safety glasses
Wear safety glasses to prevent flying or
falling material, fluid spray, etc. from get-
ting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter
removed may cause excessive engine
wear due to dirt in the air.

Tire pressure gauge
1 Remove the tire valve cap.
2 Press the tip of the tire pressure
gauge onto the tire valve.
3 Read the pressure using the gauge
gradations.
4 If the tire inflation pressure is not at
the recommended level, adjust the
pressure.
If you add too much air, press the
center of the valve to deflate.
5 After completing the tire inflation
pressure measurem ent and adjust-
ment, apply soapy water to the
valve and check for leakage.
6 Put the tire valve cap back on.
■Tire inflation pressure check interval
You should check tire inflation pressure
every two weeks, or at least once a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pres-
sure
Driving with incorrect ti re inflation pressure
may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor han-
dling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drivetrain
If a tire needs frequent inflating, have it
checked by your Lexus dealer.
■Instructions for checking tire inflation
pressure
When checking tire inflation pressure,
observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at
least 3 hours or has not been driven for more than 1 mile or 1.5 km, you will get an
accurate cold tire inflation pressure read-
ing.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is properly
inflated based only on its appearance.
●It is normal for the ti
re inflation pressure
to be higher after driving as heat is gen-
erated in the tire. Do not reduce tire infla-
tion pressure after driving.
●Never exceed the vehicle capacity
weight.
Passengers and luggage weight should
be placed so that the vehicle is balanced.

WARNING
■Proper inflation is critical to save tire
performance
Keep your tires properly inflated.
If the tires are not properly inflated, the
following conditions may occur which
could lead to an accident resulting in
death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from
overheated tires
●Air leaking from between tire and
wheel
●Wheel deformation and/or tire dam-
age
●Greater possibility of tire damage
while driving (due to road hazards,
expansion joints, sharp edges in the
road, etc.)

When trouble arises
WARNING
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recommended by the vehicle manufacturer on the vehi-
cle placard or tire inflation pr essure label (tire and load info rmation label). (If your vehicle
has tires of a different size th an the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure monitor-
ing system (TPMS-tire pressure warning system) that illuminates a low tire pressure tell-
tale (tire pressure warning light) when one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressu re telltale (tire pressure warning light) illu-
minates, you should stop and check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a si gnificantly under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation al so reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a substitute for proper
tire maintenance, and it is the driver’s respon sibility to maintain correct tire pressure, even
if under-inflation has not reac hed the level to trigger illumina tion of the TPMS low tire
pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system) mal-
function indicator to indicate when the system is not operating properly. The TPMS (tire
pressure warning system) malfunction indicator is combined with the low tire pressure
telltale (tire pressure warning light). When the system detect s a malfunction, the telltale
will flash for approximately one minute and th en remain continuously illuminated. This
sequence will continue upon subsequent vehi cle start-ups as long as the malfunction
exists. When the malfunction in dicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a variety of reasons,
including the installation of re placement or alternate tires or wheels on the vehicle that
prevent the TPMS (tire pressure warning sy stem) from functioning properly. Always
check the TPMS (tire pressure warning system ) malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensu re that the replacement or alternate tires and
wheels allow the TPMS (tire pr essure warning system) to cont inue to function properly.
NOTICE
■To ensure the tire pressure warning system operates properly
Do not install tires with differ ent specifications or makers, as the tire pressure warning
system may not operate properly.
