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 substances such as benzene or gasoline, alkaline oracidic 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 surfaces
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, especially during summer.
●Do not place items made of vinyl, plastic, or containing wax on the upholstery, 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 cleaning the inside of the windsh ield (vehicles with LDA [Lane Departure
Alert])
Be careful not to touch the camera sensor ( →P. 2 7 0 ) .
If the camera is accidentally scratched or hit, LDA may not operate properly or may
cause a malfunction.
■Cleaning the inside of the rear window
●Do not use glass cleaner to clean the rear window, as this may cause damage to the
rear window defogger heater wires or antenna. Use a cloth dampened with luke-
warm water to gently wipe the window clean. Wipe the window in strokes running

■In the following cases, the tire cannot be repaired with the emergency tire puncture
repair kit. Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional.
●When the tire is damaged due to driving without sufficient air pressure
●When the tire lost air pressure due to a crack or damage in the tire sidewall
●When the tire is visibly separated from the wheel
●When the cut or damage to the tread is 4 mm (0.16 in.) long or more
●When the wheel is damaged
●When two or more tires have been punctured
●When there is more than one hole or cut in the damaged tire
■Emergency tire puncture repair kit
●The sealant has a limited lifespan. The expiry date is marked on the bottle. The sealant
should be replaced before the expiry date. Contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional for replacement.
●The sealant stored in the emergency tire puncture repair kit can be used only once to
temporarily repair a single tire. If the sealant in the bottle and other parts of the kit have
been used and need to be purchased, contact any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional.
●The sealant can be used when the outside temperature is from -30 °C (-22 °F) to 60 °C
(140 °F).
●The kit is exclusively designed for size and type of tires originally installed on your vehi-
cle. Do not use it for tires that a different size than the original ones, or for any other
purposes.
●If the sealant gets on your clothes, it may stain.
●If the sealant adheres to a wheel or the surface of the vehicle body, the stain may not be
removable if it is not cleaned at once. Immediately wipe away the sealant with a wet
cloth.
●During operation of the kit, a loud operatio n noise is produced. This does not indicate a
malfunction.
■After a tire is repaired with the emergency tire puncture repair kit
●The tire pressure warning valve and transmitter should be replaced.
●Even if the tire inflation pressure is at the recommended level, the tire pressure warning
light may come on/flash.
■Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle. Do not use sealant whose expiry date has already
passed. Otherwise, repairs conducted using the emergency tire puncture repair kit may
not be performed properly.

CAUTION
■When fixing the flat tire
●Stop your vehicle in a safe and flat area.
●Do not touch the wheels or the area around the brakes immediately after the vehicle
has been driven.
After the vehicle has been driven, the wheels and the area around the brakes may be
extremely hot. Touching these areas with hands, feet or other body parts may result in
burns.
●Connect the valve and hose securely with the tire installed on the vehicle.
●If the hose is not properly connected to the valve, air leakage may occur or sealant
may be sprayed out.
●If the hose comes off the valve while inflating the tire, there is a risk that the hose will
move abruptly due to air pressure.
●After inflation of the tire has completed, the sealant may splatter when the hose is dis-
connected or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedure is not followed, the
sealant may spray out.
●Keep back from the tire while it is being re paired, as there is a chance of it bursting
while the repair operation is being performe d. If you notice any cracks or deforma-
tion of the tire, turn off the compressor sw itch and stop the repair operation immedi-
ately.
●The kit may overheat if operated for a long period of time. Do not operate the com-
pressor continuously for more than 10 minutes.
●Parts of the kit become hot during operation. Be careful handling the kit during and
after operation.
●Do not attach the vehicle speed warning sticker to an area other than the one indi-
cated. If the sticker is attached to an area where an SRS airbag is located, such as the
pad of the steering wheel, it may prevent the SRS air bag from operating properly.
■Driving to spread the liquid sealant evenly
●Drive the vehicle carefully at a low speed. Be especially careful when turning and cor-
nering.
●If the vehicle does not drive straight or you feel a pull through the steering wheel, stop
the vehicle and check the following:
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If tire infl ation pressure is 130 kPa (1.3 kgf/cm
2 or bar, 19 psi)
or below, this may indicate severe tire damage.

Maintain the engine speed of the second vehicle and start the hybrid system
of your vehicle by turning the power switch to ON mode.
Make sure the “READY” indicator comes on. If the indicator does not come
on, contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional.
Once the hybrid system has started, remove the jumper cables in the exact
reverse order from which they were connected.
Once the hybrid system starts, have the vehicle inspected at any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional as
soon as possible.
■Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■To prevent 12-volt battery discharge
●Turn off the headlights and the audio system while the hybrid system is off.
●Turn off any unnecessary electrical components when the vehicle is running at a low
speed for an extended period, such as in heavy traffic.
■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 discharge and the draining effects of certain electrical appli-
ances. If the vehicle is left for a long time, the 12-volt battery may discharge, and the
hybrid system may be unable to start. (The 12-volt battery recharges automatically while
the hybrid system is operating.)
■When recharging or replacing the 12-volt battery
●In some cases, it may not be possible to un lock 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 hybrid system may not start on the first attempt after the 12-volt battery has
recharged but will start normally after the second attempt. This is not a malfunction.
●The power switch mode is memorized by the vehicle. When the 12-volt battery is
reconnected, the system will return to the mo de it was in before the 12-volt battery was
discharged. Before disconnecting the 12-volt battery, turn the power switch off.
If you are unsure what mode the power switch was in before the 12-volt battery dis-
charged, be especially careful when reconnecting the 12-volt battery.

CAUTION
■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 compartment may be very hot.
●After the hybrid system has been turned off, check that the “READY” indicator is off.
When the hybrid system operating, the gasoline engine may automatically start, or
the cooling fan may suddenly operate even if the gasoline engine stops. Do not touch
or approach rotating parts such as the belt and fan, which may lead to fingers or
clothing (especially a tie, a scarf or a mu ffler) getting caught, resulting in serious
injury.
NOTICE
■When adding engine/power control unit coolant
Add coolant slowly after the hybrid system has cooled down sufficiently. Adding cool
coolant to a hot hybrid system too quickly can cause damage to the hybrid system.
■To prevent damage to the cooling system
Observe the following precautions:
●Avoid contaminating the coolant with foreign matter (such as sand or dust etc.).
●Do not use any coolant additive.
●Do not loosen the coolant reservoir caps or
water filler cap while the hybrid system and
radiator are hot.
High temperature steam or coolant could
spray out.
