When trouble arises
When the tire pressure warning light comes on (vehicles with a tire pres-
sure warning system)
Carry out the following procedure after the tire temperature has lowered suffi-
ciently.
Check the tire inflation pressure and adjust it to the appropriate level.
If the warning light does not go out 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 not equipped with a tire pressure warning valve and trans-
mitter. 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 pres-
sure warning light will go off after a few minutes.
Conditions that the tire pressure warning system may not function prop-
erly (vehicles with a tire pressure warning system)
P. 541
If the tire pressure warning light frequently comes on after blinking for 1
minute (vehicles with a tire pressure warning system)
Except hybrid model
Vehicles without a smart entry & start system: If the tire pressure warning
light comes on after blinking for 1 minute frequently when the engine switch
is turned to the “ON” position, have it checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
Vehicles with a smart entry & start system: If the tire pressure warning light
comes on after blinking for 1 minute frequently when the engine switch is
turned to IGNITION ON mode, have it checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
