Tire Pressure Warning System; Installing Tire Pressure Warning Valves And Transmitters; Initializing The Tire Pressure Warning System - Toyota COROLLA iM 2017 Service Manual

Tire pressure warning system

Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise.
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. (→P. 294)
◆

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 ID codes must be registered in the tire pressure
warning computer and the tire pressure warning system must be
initialized. Have tire pressure warning valves and transmitter ID
codes registered by your Toyota dealer. (→P. 253)

Initializing the tire pressure warning system

■
The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When rotating front and rear tires which have different tire infla-
tion pressures.
● When changing the tire size.
● When the tire inflation pressure is changed such as when chang-
ing traveling speed or load weight.
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
