9-2. If a warning light illuminates/flashes or a warning message is displayed on the meter
WARNING
If the tire pressure warning light 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 the 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
vehicle placard or tire inflation pressure label (tire and load information label). (If your
vehicle has tires of a different size than 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 moni-
toring system (TPMS-tire pressure warning system) that illuminates a low tire pressure
telltale (tire pressure warning light) when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire pressure telltale (tire pressure warning
light) illuminates, you should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under-inflated tire causes the tire
to overheat and can lead to tire failure. Under-inflation also 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 responsibility to maintain correct tire pressure, even
if under-inflation has not reached the level to trigger illumination 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 detects a malfunction, the telltale
will flash for approximately one minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups as long as the malfunction
exists. When the malfunction indicator 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 replacement or alternate tires or wheels on the vehicle that
prevent the TPMS (tire pressure warning system) from functioning properly. Always
check the TPMS (tire pressure warning system) malfunction telltale after replacing one or
