Installing tire pressure warning valves and transmitters
When 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 tire pressure warning valve and transmitter ID codes
must be registered in the tire pressure warning computer and the tire
pressure warning system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by your Toyota
dealer
. (P. 311)
Initializing the tire pressure warning system
■
The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When rotating the tires on vehicles differing with front and rear tire
inflation pressure.
● When changing the tire size.
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the pressure benchmark.
