LC500_LC500h_OM_OM11405U_(U)
WARNING
●Decelerate to the lowest appropriate speed as soon as possible. Do not drive over 50
mph (80 km/h).
●Check and adjust the tire in flation pressure immediately.
●If the tire pressure warning lig ht comes on even after tire inflation pressure adjustment,
it is probable that you have a flat tire. Have the flat tire replaced by the nearest Lexus
dealer.
●Avoid abrupt maneuvering and braking. If th e vehicle tires deteriorate, you could lose
control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recommended by the vehicle manufacturer on the vehi-
cle placard or tire inflation pr essure label (tire and load info rmation label). (If your vehicle
has tires of a different size th an the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure monitor-
ing system (TPMS-tire pressure warning system) that illuminates a low tire pressure tell-
tale (tire pressure warning light) when one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressu re telltale (tire pressure warning light) illu-
minates, you should stop and check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a si gnificantly under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation al so reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a substitute for proper
tire maintenance, and it is the driver’s respon sibility to maintain correct tire pressure, even
if under-inflation has not reac hed the level to trigger illumina tion of the TPMS low tire
pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system) mal-
function indicator to indicate when the system is not operating properly. The TPMS (tire
pressure warning system) malfunction indicator is combined with the low tire pressure
telltale (tire pressure warning light). When the system detect s a malfunction, the telltale
will flash for approximately one minute and th en remain continuously illuminated. This
sequence will continue upon subsequent vehi cle start-ups as long as the malfunction
exists. When the malfunction in dicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a variety of reasons,
including the installation of re placement or alternate tires or wheels on the vehicle that
prevent the TPMS (tire pressure warning sy stem) from functioning properly. Always
check the TPMS (tire pressure warning system ) malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensu re that the replacement or alternate tires and
wheels allow the TPMS (tire pr essure warning system) to cont inue to function properly.

LC500_LC500h_OM_OM11405U_(U)
Take your vehicle to the nearest Lexus
dealer or authorized tire dealer as
soon as possible if any tire goes flat.
The vehicle can be driven for a maximum
of 100 miles (160 km) at a speed below 50
mph (80 km/h) after the tire pressure
warning light comes on. ( P.340)
A run-flat tire has a mark on the
side wall.

peratures)
You cannot continue driving for up to 100
miles (160 km).
■For the detailed information on run-flat
tires
See the tire warranty booklet.
If you have a flat tire
