When trouble arises
When a tire is replaced with a spare tire (vehicles with a compact spare tire and
the tire pressure warning system)
The compact spare tire is not equipped with a tire pressure warning valve and
transmitter. If a tire goes flat, the tire pressure warning light will not turn off even
though the flat tire has been replaced with the spare tire. Replace the spare tire
with the repaired tire and adjust the tire inflation pressure. The tire pressure
warning light will go off after a few minutes.

If the tire pressure warning light comes on (vehicles with the tire pressure warn-
ing system)
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.
Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation
pressure immediately.
Vehicles with a spare tire: If the tire pressure warning light comes on even
after tire inflation pressure adjustment, it is probable that you have a flat tire.
Check the tires. If a tire is flat, change it with the spare tire and have the flat
tire repaired by the nearest any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
Vehicles with an emergency tire puncture repair kit: If the tire pressure warn-
ing light comes on even after tire inflation pressure adjustment, it is probable
that you have a flat tire. Check the tires. If a tire is flat, repair the flat tire by
using emergency tire puncture repair kit.
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 (vehicles with the tire pressure
warning system)
The tire pressure warning system may not activate immediately.
NOTICE
To ensure the tire pressure warning system operates properly (vehicles with the
tire pressure warning system)
Do not install tires with different specifications or makers, as the tire pressure
warning system may not operate properly.
