Lexus authorized repairer, or any reliable repairer.
■For your safety
●Please drive safely.The function of this system is to assist
you in making the Emergency Call in case of accidents as traffic accidents or sudden medical emergencies, and it
does not protect the driver or the pas- sengers in any way. Please drive safely and fasten your seatbelts at all times
for your safety.
●In case of an emergency, make lives the top priority.
●If you smell anything burning or another unusual smell, do not stay
inside the vehicle and evacuate to a safe area immediately.
●Since the system detects shocks, the automatic reporting may not always
occur synchronized with the operation of the airbag system. (If the vehicle is bumped from behind, etc.)
●The airbag may not inflate even in case
of an accident, if it does not involve high impact. In such cases, the system may not make emergency calls auto-
matically. The system may also not make automatic emergency calls even if the airbag has been inflated. If any of
these should occur, please report to the Public Safety Answering Point (PSAP) by operating the “SOS” but-
ton.
●For safety, do not make the Emergency Call while driving.
Making calls during driving may cause mishandling of th e steering wheel, which may lead to unexpected acci-
dents. Stop the vehicle and confirm the safety of the area before making the Emer-
gency Call.
●When changing fuses, please use fuses that correspond to the described stan-dard.
If you use fuses other than those described, it may cause ignition or smoke in the circuit and may lead to a
fire.
●Using the system while there is smoke or an unusual smell may cause a fire. Stop using the system immediately and
consult any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
NOTICE

6-1. Maintenance and care
■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 or in the trunk. ( P.68)
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.35) 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.

7-2. Steps to take in an emergency
ponents when the vehicle is running at a low speed for an extended period, such as in heavy traffic.
■When the 12-volt battery is removed or
discharged
●Information stored in the ECU is cleared.
When the 12-volt battery is depleted, have the vehicle inspected at any autho-rized Lexus retailer or Lexus authorized
repairer.
●Some systems may require initialization.
( P.436)
■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 any autho- rized Lexus retailer or Lexus authorized repairer.
■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 <hybrid system>
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 entry &
start system when the 12-volt battery is discharged. Use the wireless remote control or the mechanical key to lock or
unlock the doors.
●The engine <hybrid system> 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 <power 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 <power switch> off. If you are unsure what mode the engine
switch <power switch> was in before the 12-volt battery discharged, be especially careful when reconnecting the 12-volt
battery.
●If the 12-volt battery discharges, it may
not be possible to shift the shift position to other positions. In this case, the vehicle cannot be towed without lifting both rear
wheels because the rear wheels will be locked. ( P.363)
■When replacing the 12-volt battery
●Use a Central Degassing type 12-volt battery (European Regulations).
●LC500: Use a 12-volt battery that the case size is same as the previous one (LN4), 20 hour rate capacity (20HR) is
equivalent (80Ah) or greater, and per- formance rating (CCA) is equivalent (685A) or greater.
LC500h: Use a 12-volt battery that the case size is same as the previous one (LN3), 20 hour rate capacity (20HR) is
equivalent (70Ah) or greater, and perfor- mance rating (CCA) is equivalent
(600A) or greater. • If the sizes differ, the 12-volt battery can-not be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehicle is not used is a short time, the 12-volt battery
may discharge and engine <hybrid sys- tem> may not be able to start.
●Use a 12-volt battery with a handle. If a 12-volt battery without a handle is used, removal is more difficult.
●After exchanging, firmly attach the fol-lowing items to the exhaust hole of the 12-
volt battery. • Use the exhaust hose that was attached to the 12-volt battery before exchanging.
• Use the exhaust hole plug included with the 12-volt battery exchanged or the one installed on the battery prior to the
exchange. (Depending on the 12-volt battery to be exchanged, the exhaust hole may be plugged.)

WARNING
■When inspecting under the hood of your vehicle
Observe the following precautions. Failure to do so may result in serious
injury such as burns.
●If steam is seen coming from under the hood, do not open the hood until the steam has subsided. The engine com-
partment may be very hot.
●Keep hands and clothing (especially a tie, a scarf or a muffler) away from the fan and belts. Failure to do so may
cause the hands or clothing to be caught, resulting in serious injury.
●While the engine and radiator are hot, do not loosen or remove the coolant
inlet cap or coolant reservoir cap. High temperature steam or coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the engine has
cooled down sufficiently. Adding cool coolant to a hot engine too quickly can cause damage to the engine.
■To prevent damage to the cooling sys-
tem
Observe the following precautions:
●Avoid contaminating the coolant with foreign matter (such as sand or dust etc.).
●Do not use any coolant additive.
