STARTING AND DRIVING
434If the low tire pressure warning light does not go off or comes
on during driving, it indicates that tire inflation pressure is low.
Make sure there is no flat tire. If the light comes on again even
after tire inflation pressure adjustment, you may have a flat tire.
If there is not adequate air pressure in the tires, the light will not
go off.
The light may turn on due to natural causes such as natural air
leaks or tire inflation pressure changes caused by
temperature. In this case, adjusting the tire inflation pressure
will turn off the light.
The tire pressure warning system is not a substitute for
checking tire inflation pressure.
For details about adjusting the tire inflation pressure, see
“Checking tire inflation pressure” on page 539.
If the low tire pressure warning light comes on, the action you
must take is different depending on the type of tires used.Vehicles with run−flat tires:
Stop your vehicle at a safe place as soon as possible and
check that the tire inflation pressure is as specified on the tire
and loading information label. If the low tire pressure warning
light comes on even after tire inflation pressure adjustment, it
is probable that you have a flat tire. If you cannot verify the tire
inflation pressure soon, go to the nearest Lexus dealer or
authorized tire dealer at the moderate speed and do not ever
exceed 90 km/h (55 mph) and have all your vehicle’s tires
checked and adjusted. And whether there is a flat tire or not
should be also checked at this time. If any tire must be
replaced, see “If you have a flat tire” on page 468.
If your vehicle is equipped with spare tire, the spare is not
equipped with the tire pressure sensor. So, the low tire
pressure warning light remains on even if the spare tire is
mounted.
The light goes off a few minutes after air is put into the deflated
tire.
