8-2. Steps to take in an emergency
When the tire pressure warning light comes on
■
Inspect the tires to check if a tire is punctured.
If a tire is punctured: P. 646
If none of the tires are punctured:
Turn the engine switch off then turn it to IGNITION ON mode. Check if the tire pressure
warning light comes on or blinks.
If the tire pressure warning light comes on

After the temperature of the tires has lowered sufficiently, check the inflation pressure
1
of each tire and adjust them to the specified level.
If the warning light does not turn off even after several minutes have elapsed, check
2
that the inflation pressure of each tire is at the specified level and perform initialization.
(P. 586)
If the warning light does not turn off several minutes after the initialization has been per-
formed, have the vehicle inspected by your Lexus dealer immediately.
If the tire pressure warning light blinks for 1 minute then stays on

There may be a malfunction in the tire pressure warning system. Have the vehicle
inspected by your Lexus dealer immediately.
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).
When a tire is replaced with a spare tire
■
The compact spare tire is not equipped with a tire pressure warning valve and transmit-
ter. 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.

P. 589
Warning buzzer
■
In some cases, the buzzer may not be heard due to being in a noisy location or audio
sound.

Some functions can be customized. (P. 699)
