■ The tire pressure warning system must be initialized in the following circumstances:
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 (with 7-inch display)
1. Park the vehicle in a safe place and stop the engine for 20 minutes or more.
Initialization cannot be performed while the vehicle is moving.
2. Adjust the tire inflation pressure to the specified cold tire inflation pressure level.
Make sure to adjust the tire pressure to the specified cold tire inflation pressure level. The tire pressure warning system will operate based on this pressure level.
3. Start the engine.
4. Press or
of the meter
control switches on the steering
wheel and select .
5. Press or
of the meter
control switches, select
"Vehicle Settings" and then
press and hold .
6. Press or of the meter

and hold .
"Setting Tire Pressure Warning System" will be displayed on the multi-information display and the tire pressure warning light will blink 3 times.
When the message disappears, initialization is complete.
A message is displayed on the multi-information display. Also, "--" is displayed for inflation pressure of each tire on the multi-information display while the tire pressure warning system determines the position.
8. Drive straight (with occasional left and right turns) at approximately 25mph (40 km/h) or more for approximately 10 to 30 minutes.
When initialization is complete, the inflation pressure of each tire will be displayed on the multi-information display.
Even if the vehicle is not driven at approximately 25 mph (40 km/h) or more, initialization can be completed by driving for a long time.
However, if initialization does not complete after driving for 1 hour or more, park the vehicle in a safe place for approximately 20 minutes and then drive the vehicle again.

■When initializing
■The initialization operation
■If the tire pressure warning system is not initialized properly
- Vehicle is not driven at approximately 25 mph (40 km/h) or more
- Vehicle is driven on unpaved roads
- Vehicle is driven near other vehicles and system cannot recognize tire pressure warning valve and transmitters of your vehicle over those of other vehicles.
- If the vehicle is driven in heavy traffic or another situation where other vehicles are driven close by, it may take time for the system to recognize the tire pressure warning valve and transmitters of your vehicle over those of other vehicles.
If initialization does not complete after driving for 1 hour or more, park the vehicle in a safe place for approximately 20 minutes and then drive the vehicle again.
Perform the initialization procedure again.
- If, when attempting to start initialization, the tire pressure warning light does not blink 3 times.
- If, when the vehicle has been driven for about 20 minutes after performing initialization, the tire pressure warning light blinks for approximately 1 minute and then illuminates.
If the inflation pressure of each tire is still not displayed, have the vehicle inspected by your Toyota dealer.
WARNING
■When initializing the tire pressure warning system
Do not initialize tire inflation pressure without first adjusting the tire inflation pressure to the specified level. Otherwise, the tire pressure warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation pressure is actually normal.
