TPMS (tire pressure warning sys-

tem) malfunctions may occur for a

variety of reasons, including the

installation of replacement or

alternate tires or wheels on the

vehicle that prevent the TPMS

check the TPMS (tire pressure

warning system) malfunction tell-

tale after replacing one or more

tires or wheels on your vehicle to

ensure that the replacement or

alternate tires and wheels allow

the TPMS (tire pressure warning

system) to continue to function

properly.

play shows warnings for

incorrectly performed oper-

ations, and messages that

action for the message.

If a warning message is dis-

played again after the

appropriate actions have

been performed, contact

your Toyota dealer.
