WARNING

■

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 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 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 pressure 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 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

more tires or wheels on your vehicle to ensure that the replacement or alternate tires and

wheels allow the TPMS (tire pressure warning system) to continue to function properly.

NOTICE

■

To ensure the tire pressure warning system operates properly

Do not install tires with different specifications or makers, as the tire pressure warning

system may not operate properly.

When replacing the tires

When removing or fitting the wheels,

tires or the tire pressure warning valve

and transmitter, contact your Lexus
