■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to maintain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or brush to apply the foam. Rub in overlapping circles. Do not use water. Wipe dirty surfaces and letthem dry. Excellent results are obtained by keeping the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the belts periodically for excessive wear, fraying or cuts.
■When cleaning the carpeted portions of the glove box, console box, etc.
If a strong adhesive tape is used, there is a possibility that the surface of the carpet could be damaged.
WARNING
■Water in the vehicle
●Do not splash or spill liquid in the vehicle, such as on the floor, in the hybrid battery (traction battery) air vents, and in the trunk. Doing so may cause the hybrid battery, electrical components, etc. to malfunction or
catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet. ( P. 44) 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 wind-
shield, obstructing the driver’s view and leading to an accident, resulting in death or serious injury.

Turn the compressor switch on to inflate the tire until the recommended tire
inflation pressure is reached. Drive for about 5 km (3 miles) and then perform
step .
Attach the air release cap to the end
of the hose.
If the air release cap is not attached, the sealant may leak and the vehicle mayget dirty.
Store the bottle in the trunk while it is connected to the compressor.
Taking precautions to avoid sudden braking, sudden acceleration and sharp
turns, drive carefully at under 80 km /h (50 mph) to any authorized Lexus
retailer or Lexus authorized repairer, or any reliable repairer that is less than
100 km (62 miles) away for tire repair or replacement.

●The sealant has a limited lifespa n. The expiry date is shown on the bottle. The sealant
should be replaced before the expiry date. Contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer 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 has been used and need to be purchased, contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
●The sealant can be used when the outside temperature is from -40 C (-40 F) to 60 C (140 F).

WARNING
■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 beextremely 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 procedures not followed, the
sealant may spray out.
●Keep back from the tire while it is being repaired, 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 switch and stop the repair operation immedi- ately.
●The repair kit may overheat if operated for a long period of time. Do not operate the
repair kit continuously for more than 35 minutes.
●Parts of the repair kit become hot during op eration. Be careful handling the repair kit during and after operation. Do not touch the metal part connecting the bottle and the
compressor. It will be extremely hot.
●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 inflation pressure is 130 kPa (1.3 kgf/cm2 or b ar, 1 9 p si)or less, the tire may be severely damaged.

■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 componen ts 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 unlock the doors using the smart entry & startsystem when the 12-volt battery is discharged. Use the wireless remote control or themechanical key to lock or unlock the doors.
●The hybrid system may not start on the first attempt after the 12-volt battery hasrecharged 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 mode it was in before the 12-volt battery was discharged. Before disconnecting the 12-v olt 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.
WARNING
■Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flammable gas that may be emitted from the 12-volt battery:
●Make sure each jumper cable is connected to the correct terminal and that it is notunintentionally in contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+” terminal to come
into contact with any other parts or metal surfaces in the area, such as brackets or unpainted metal.
●Do not allow the + and - clamps of the jumper cables to come into contact with each
other.
●Do not smoke, use matches, cigarette lighters or allow open flame near the 12-volt battery.

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 h ood, 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 indicator on the power
switch and the “READY” indicator are off. When the hybrid system is operating, the gasoline engine may automatically start, orthe cooling fan may suddenly operate even if the gasoline engine stops. Do not touch
or approach rotating parts such as the fan, which may lead to fingers or clothing (especially a tie, a scarf or a muffler) getting caught, resulting in serious injury.
●Do not loosen the coolant inlet cap or thecoolant reservoir caps while the hybrid sys-tem and radiator are hot.
High temperature steam or coolant could spray out.
