WARNING
■When installing a child restraint system
●Never use a rear-facing child restraint system
on the front passenger seat when the airbag manual on-off switch is on. ( P. 54)
The force of the rapid inflation of the front
passenger airbag can cause death or serious injury to children in the event of an accident.
●There is a label(s) on the passenger side sunvisor, indicating it is forbidden to attach a rear-facing child restraint system to the front pas-
senger seat. Details of the label(s) are shown in the illustra-tion below.

NOTICE
●To prevent 12-volt battery discharge, do not operate the rear sunshade when the hybrid system is off.
●Observe the following precautions to ensure normal operation of the rear sunshade
and rear door sunshades.
• Do not place excessive load on the moto r or other components of the rear sun- shade.
• Do not place objects where they may hinder opening and closing operations. • Do not attach items to the rear sunshade and rear door sunshades.• Keep the opening clean and clear of obstructions.
• Do not operate the rear sunshade continuously for long periods of time.

Maintenance and care
GS450h_300h_OM_OM30F92E_(EE)
■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.

When trouble arises
GS450h_300h_OM_OM30F92E_(EE)
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.
