Installing tire pressure warning valves and transmittersWhen replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be regi stered in the tire pressure warn-
ing computer and the tire pressure warning system must be initial-
ized. Have tire pressure warning valve and transmitter ID codes
registered by your Toyota dealer. ( P. 369)
■ The tire pressure warning system must be initialized in the fol-
lowing circumstances:
●When the tire inflation pres sure is changed such as when
changing travelling speed or load weight
● When changing the tire size
When the tire pressure warning syst em is initialized, the current tire
inflation pressure is set as the benchmark pressure.
■ How to initialize the tire pressure warning system
Park the vehicle in a safe pl ace and turn the engine switch
(vehicles without a smart key system) or the “ENGINE START
STOP” switch (vehicles with a smart key system) off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. ( P. 474)
Make sure to adjust the tire pressure to the specified cold tire
inflation pressure level. The ti re pressure warning system will
operate based on this pressure level.
Turn the engine switch to the “O N” position (vehicles without a
smart key system) or “ENGINE START STOP” switch to IGNI-
TION ON mode (vehicles with a smart key system).
