WARNING
The engine compartment contains many
mechanisms and fluids that may move
suddenly, become hot, or become elec-
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,

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

( P.296)
■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.
3046-3. Do-it-yourself maintenance
LC500_LC500h_OM_OM11405U_(U)• An auxiliary-supported run-flat tire is
equipped.
• If a window tint that affects the radio wave
signals is installed.
• If there is a lot of snow or ice on the vehi- cle, particularly around the wheels or
wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If wheel without tire pressure warning valves and transmitters are used.
• If the ID code on the tire pressure warn-
ing valves and transmitters is not regis-
tered in the tire pressure warning
computer.
●Performance may be affected in the fol-
lowing situations.
• Near a TV tower, electric power plant, gas station, radio stat
ion, large display,
airport or other fac ility that generates
strong radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or other wireless
communication device
If tire position information is not correctly
displayed due to the radio wave conditions,
the display may be corrected by driving and
changing the radio wave conditions.
●When the vehicle is parked, the time
taken for the warning to start or go off
could be extended.
●When tire inflation pr essure declines rap-
idly for example when a tire has burst, the
warning may not function.

WARNING
■When installing the tire
Failure to follow these precautions could
cause the wheel nuts to loosen and the
tire to fall off, result ing in death or serious
injury.
●Never use oil or grease on the wheel
bolts or wheel nuts.
Oil and grease may cause the wheel
nuts to be excessively tightened, lead-
ing to bolt or disc wheel damage. In
addition, the oil or grease can cause
the wheel nuts to loosen and the wheel
may fall off, causing a serious accident.
Remove any oil or grease from the
wheel bolts or wheel nuts.
●Have the wheel nuts tightened with a
torque wrench to 103.3 ft•lbf (140
N•m, 14.3 kgf•m) soon as possible
after changing wheels.
●Do not attach a heavily damaged
wheel ornament, as it may fly off the
wheel while the vehicle is moving.
●When installing a tire, only use wheel
nuts that have been specifically
designed for that wheel.
●If there are any cracks or deformations
in the bolt screws, nut threads or bolt
holes of the wheel, have the vehicle
inspected by your Lexus dealer.

If your vehicle needs to be
towed
If towing is necessary, we recom-
mend having your vehicle towed by
your Lexus dealer or commercial
towing service, using a wheel-lift
type truck or flatbed truck.
Use a safety chain system for all
towing, and abide by all state/pro-
vincial and local laws.
WARNING
Observe the following precautions.
Failure to do so may result in death or
serious injury.
■When towing the vehicle
LC500: Be sure to transport the vehicle
with all four wheels raised off the ground.
If the vehicle is towed with the tires con-
tacting the ground, the drivetrain and
related parts may be damaged or an
accident may occur due to a change in
direction of the vehicle.
LC500h: Be sure to transport the vehi-
cle with all four wheels raised off the
ground. If the vehicle is towed with the
tires contacting the ground, the drive-
train and related parts may be damaged,
an accident may occur due to a change
in direction of the vehicle or electricity
generated by the operation of the motor
may cause a fire to occur depending on
the nature of the damage or malfunction.
■While towing
●When towing using cables or chains,
avoid sudden starts, etc. which place
excessive stress on the towing eyelets,
cables or chains. The towing eyelets,
cables or chains may become dam-
aged, broken debris may hit people,
and cause serious damage.
●Do not turn the engine switch
This may lead to an accident as the
rear wheels will be locked by the park-
ing lock.
Also, there is a possibility that the
steering wheel is locked and cannot be
operated.

When trouble arises
In the following situations, it is not pos-
sible to be towed by another vehicle
using cables or chains, as the rear
wheels may be locked due to the park-
ing lock. Contact your Lexus dealer or
commercial towing service.
There is a malfunction in the shift control system. (
P.143, 147, 346)
There is a malfunction in the engine
immobilizer system
There is a malfunction in the smart
access system with push-button
start. ( P.355)
The 12-volt battery is discharged.
( P.357)
The following may indicate a problem
with your transmission. Contact your
Lexus dealer or commercial towing
service before towing.
LC500: The engine is running but
the vehicle does not move.
LC500h: The hybrid system warn-
ing message is shown on the multi-
information display and the vehicle
does not move.
The vehicle makes an abnormal
sound.
Do not tow with a sling-type truck to
prevent body damage.
WARNING
■Installing towing eyelets to the vehi-
cle
Make sure that towing eyelets are
installed securely.
If not securely installed, towing eyelets
may come loose during towing.
NOTICE
■To prevent damage to the vehicle
when towing using a wheel-lift type
truck
●Do not tow the vehicle from the rear
when the engine switch
nism is not strong enough to hold the
front wheels straight.
●When raising the vehicle, ensure ade-
quate ground clearance for towing at
the opposite end of the raised vehicle.
Without adequate clearance, the vehi-
cle could be damaged while being
towed.
■To prevent damage to the vehicle
when towing with a sling-type truck
Do not tow with a sling-type truck, either
from the front or rear.
■To prevent damage to the vehicle
during emergency towing
Do not secure cables or chains to the
suspension components.
