When The Tire Pressure Warning Light Comes On; The Tire Pressure Warning Light May Come On Due To Natural Causes; When A Tire Is Replaced With A Spare Tire; If The Tire Pressure Warning System Is Not Functioning - Toyota Avanza Owner's Manual

When the tire pressure warning light comes on (vehicles with a tire pres-
■
sure warning system)
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: →P. 314
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered suffi-
ciently.
Check the tire inflation pressure and adjust to the appropriate level.
●
If the warning light does not go out even after several minutes, check that
●
the tire inflation pressure is at the specified level and carry out initialization.
The warning light may come on again if the above operations are conducted
without first allowing the tire temperature to lower sufficiently.

The tire pressure warning light may come on due to natural causes

■
(vehicles with a tire pressure warning system)
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 (vehicles with a tire pressure
■
warning system)
The spare tire is also equipped with a tire pressure warning valve and trans-
mitter. The tire pressure warning light will turn on if the tire inflation pressure
of the spare tire is low. 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 pres-
sure. The tire pressure warning light will go off after a few minutes.
If the tire pressure warning system is not functioning (vehicles with a
■
tire pressure warning system)
The tire pressure warning system will be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.)
If tires not equipped with tire pressure warning valves and transmitters are
●
used
If the ID code on the tire pressure warning valves and transmitters is not
●
registered in the tire pressure warning computer
If the tire inflation pressure is higher than the specified tire air pressure.
