LC500_LC500h_OM_OM11405U_(U)
■CFRP (Carbon Fiber Reinforced Plas-
tic) parts (if equipped)
CFRP is used for the scuff plates. When
cleaning the scuff plates, remove dirt using
a water-dampened soft cloth or synthetic
chamois, and then wipe the surface with a
dry soft cloth to remove any remaining
moisture.
WARNING
■Water in the vehicle
●LC500: Do not splash or spill liquid in
the vehicle.
Doing so may cause electrical compo-
nents etc. to malfunction or catch fire.
LC500h: Do not splash or spill liquid
in the vehicle, such as on the floor, on
the rear seats, in the hybrid battery
(traction battery) air vents, and in the
trunk. ( P.60)
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.28)
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, resulting in
death or serious injury.
NOTICE
■Cleaning detergents
●Do not use the following types of
detergent, as they may discolor the
vehicle interior or cause streaks or
damage to painted surfaces:
• Non-seat portions: Organic sub- stances such as benzene or gasoline,
alkaline or acidic solutions, dye, and
bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alcohol
●Do not use polish wax or polish
cleaner. The instrument panel’s or
other interior part’s painted surface
may be damaged.
■Preventing damage to leather sur-
faces
Observe the following precautions to
avoid damage to and deterioration of
leather surfaces:
●Remove any dust or dirt from leather
surfaces immediately.
●Do not expose the vehicle to direct
sunlight for extended periods of time.
Park the vehicle in the shade, espe-
cially during summer.
●Do not place items made of vinyl, plas-
tic, or containing wax on the uphol-
stery, as they may stick to the leather
surface if the vehicle interior heats up
significantly.
■Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system
may be damaged if water comes into
contact with electrical components such
as the audio system above or under the
floor of the vehicle. Water may also
cause the body to rust.

When trouble arises
■Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage temporarily drops, the
electric power steering syst em warning light may come on and the warning buzzer may
sound.
■Tire pressure warning light
When a malfunction occurs in the tire pressu re warning system, the tire pressure warning
light blinks to warn the driver . However, if the warning light blinks for 1 minute, and then
remains illuminated, making it difficult to determine whether the warning light is blinking,
turn the engine switch from off to IGNITION ON mode and
check if the warning light blinks.
■When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Pushing the tire pres-
sure warning reset switch will not turn off the tire pressure warning light.
■The tire pressure warning light may come on due to natural causes
The tire pressure warnin g light may come on due to natural causes such as natural air leaks
and tire inflation pressure chan ges caused by temperature. In this case, adjusting the tire
inflation pressure will turn off the warning light (after a few minutes).
■Conditions that the tire pressure wa rning system may not function properly
 P.303
■If the tire pressure warning light freque ntly comes on after blinking for 1 minute
If the tire pressure warning lig ht frequently comes on after blinking for 1 minute when the
engine switch is turned to IGNITION ON mode , have it
checked by your Lexus dealer.
■Warning buzzer
In some cases, the buzzer may not be heard du e to being in a noisy location or audio sound.
■Customization
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features:  P.391)
WARNING
■If both the ABS and the brake sy stem warning lights remain on
Stop your vehicle in a safe place immediately and contact your Lexus dealer. The vehicle
will become extremely unstable during brakin g, and the ABS system may fail, which could
cause an accident resulting in death or serious injury.
■When the electric power steering system warning light comes on
When the light comes on in yellow, the assist to the power steering is restricted. When the
light comes on red, the assist to the power steering is lost and handling operations of the
steering wheel become extremely heavy. When steering wheel operations are heavier
than usual, grip the steering wheel firmly and operate it using more force than usual.
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a loss of vehi-
cle control and result in death or serious injury.

When trouble arises
5 Start the engine of the second vehi-
cle. Increase the engine speed
slightly and maintain at that level for
approximately 5 minutes to
recharge the 12-volt battery of your
vehicle.
6 Open and close any of the door of
your vehicle with the engine switch
off.
7 Maintain the engine speed of the
second vehicle and start the engine
of your vehicle by
turning the engine switch switch> to IGNITION ON mode
.
8 Once the vehicle’s engine system> has started, remove the
jumper cables in the exact reverse
order from which they were con-
nected.
9 Close the exclusive jump starting
terminal cover, and reinstall the fuse
box cover to tits original position.
Once the engine starts,
have the vehicle inspected at your Lexus
dealer as soon as possible.
■Starting the engine
when the 12-volt battery is discharged
The engine cannot be
started by push-starting.
■To prevent 12-volt battery discharge
●Turn off the headlights and the audio sys-
tem while the engine is
stopped.
●Turn off any unnecessary electrical com-
ponents when the vehicle is running at a
low speed for an extended period, such
as in heavy traffic.
■When the 12-volt batte ry is removed or
discharged
●Information stored in the ECU is cleared.
When the 12-volt battery is depleted,
have the vehicle inspected at your Lexus
dealer.
●Some systems may requ ire initialization.
(  P.403)
■When removing the 12-volt battery ter-
minals
When the 12-volt battery terminals are
removed, the information stored in the
ECU is cleared. Before removing the 12-
volt battery terminals, contact your Lexus
dealer.
■Charging the 12-volt battery
The electricity stored in the 12-volt battery
will discharge gradually even when the
vehicle is not in use, due to natural dis-
charge and the draining effects of certain
electrical appliances. If the vehicle is left for
a long time, the 12-volt battery may dis-
charge, and the engine
may be unable to start. (The 12-volt battery
recharges automatically during driving.)
■When recharging or replacing the 12-
volt battery
●In some cases, it may not be possible to
unlock the doors using the smart access
system with push-button start when the
12-volt battery is discharged. Use the
wireless remote control or the mechani-
cal key to lock or unlock the doors.
●The engine may not start
on the first attempt after the 12-volt bat-
tery has recharged but will start normally
after the second attempt. This is not a
malfunction.
●The engine switch mode
is memorized by the vehicle. When the
12-volt battery is reconnected, the system
will return to the mode it was in before
the 12-volt battery was discharged.
Before disconnecting the 12-volt battery,
turn the engine switch off.
If you are unsure wh at mode the engine
switch was in before the
12-volt battery discharged, be especially
careful when reconnecting the 12-volt
battery.
