■
The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural air
leaks and tire inflation pressure changes caused by temperature. In this case, adjusting
the tire inflation pressure will turn off the warning light (after a few minutes).
WARNING
■
If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a loss of
vehicle control and result in death or serious injury.
Vehicles with run-flat tires:
●
Decelerate to the lowest appropriate speed as soon as possible. Do not drive over 50
mph (80 km/h).
Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressure
●
immediately.
●
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
