When trouble arises
COROLLA_TMMMS_TMMC_U (OM02494U)■
When a tire is replaced with a spare tire (vehicles with a 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.
■Conditions that the tire pressure warning system may not function
properly (vehicles with a tire pressure warning system)
The tire pressure warning system will be disabled in the following condi-
tions:
(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 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies are
nearby
●If a radio set at similar frequency is in use in the vehicle
●If a window tint that affects the radio wave signals is installed
●If there is a lot of snow or ice on the vehicle, in particular around the
wheels or wheel housings
●If non-genuine Toyota wheels are used (Even if you use Toyota wheels,
the tire pressure warning system may not work properly with some types
of tires.)
●If tire chains are used
■If the tire pressure warning light frequently comes on after blinking
for 1 minute (vehicles with a tire pressure warning system)
If the tire pressure warning light frequently comes on after blinking for 1
minute when the engine switch is turned on, have it checked by your
Toyota dealer.
■Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or an
audio sound.
■Electric power steering system warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering system warning light may come on and the
warning buzzer may sound.
