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. 480)
◆
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 valve and transmitter ID
codes registered by your Toyota dealer. (P. 435)
◆
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 pressure warning system 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 place and turn the power switch (vehi-
1
cles without a smart key system) or the power 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 inflation
2
pressure level. (P. 541)
Make sure to adjust the tire pressure to the specified cold tire infla-
tion pressure level. The tire pressure warning system will operate
based on this pressure level.
