Toyota Corolla Cross: Installing tire pressure warning valves and transmitters

Toyota Corolla Cross (2022-2024) Owner's Manual / Maintenance and care / Do-it-yourself maintenance / 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.

■When replacing the tires and wheels

If the ID code of the tire pressure warning valve and transmitter is not registered, the tire pressure warning system will not work properly. After driving for about 20 minutes, the tire pressure warning light blinks for 1 minute and stays on to indicate a system malfunction.

NOTICE

■Repairing or replacing tires, wheels, tire pressure warning valves, transmitters and tire valve caps

  • When removing or fitting the wheels, tires or the tire pressure warning valves and transmitters, contact your Toyota dealer as the tire pressure warning valves and transmitters may be damaged if not handled correctly.
  • Make sure to install the tire valve caps. If the tire valve caps are not installed, water could enter the tire pressure warning valves and the tire pressure warning valves could be bound.
  • When replacing tire valve caps, do not use tire valve caps other than those specified. The cap may become stuck.

■To avoid damage to the tire pressure warning valves and transmitters

When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sealant is used, contact your Toyota dealer or other qualified service shop as soon as possible. Make sure to replace the tire pressure warning valve and transmitter when replacing the tire.

Initializing the tire pressure warning system

■ The tire pressure warning system must be initialized in the following circumstances:

  • When rotating the tires.
  • When changing the tire.
  • After registering the ID codes.
  • When changing between two registered wheel sets.

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

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. 4.2-inch display meter: Press or of the meter control switch to select .

    7-inch display meter: Press or of the meter control switch to select .

5. 4.2-inch display meter: Press or to select "Vehicle Settings" and then press and hold .

    7-inch display meter: Press or to select "Vehicle Settings" and then press and hold .

6. 4.2-inch display meter: Press or to select "TPWS setting" and then press .

    7-inch display meter: Press or to select "TPWS setting" and then press .

7. 4.2-inch display meter: Press or to select "Set Pressure". Then press and hold .

    7-inch display meter: Press or to select "Set Pressure". Then press and hold .

After setting the tire inflation pressure, a message indicating that setting has been completed will be displayed on the multi-information display.

Do-it-yourself maintenance

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 25 mph (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

  • Initialization is performed while driving at a vehicle speed of approximately 25 mph (40 km/h) or more.
  • Make sure to carry out initialization after adjusting the tire inflation pressure.

    Also, make sure the tires are cold before carrying out initialization or tire inflation pressure adjustment.

  • The tire pressure warning system can be initialized by yourself, but depending on the driving conditions and driving environment, initialization may take some time to complete.

■The initialization operation

  • If you have accidentally turned the engine switch to OFF during initialization, it is not necessary to restart the initialization again as initialization will restart automatically when the engine switch has been turned to ON for the next time.
  • If you accidentally perform initial ization when initialization is not necessary, adjust the tire inflation pressure to the specified level when the tires are cold, and conduct initialization again.
  • While the position of each tire is being determined and the inflation pressures are not being displayed on the multi-information display, if the inflation pressure of a tire drops, the tire pressure warning light will come on.

■If the tire pressure warning system is not initialized properly

  • In the following situations, initialization may take longer than usual to be completed or may not be possible. Normally, initialization completes within approximately 30 minutes.
    • 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.
  • If the vehicle is reversed during initialization, the data up to that point is reset, so perform the initialization procedure again from the beginning.
  • In the following situations, initialization will not be started or was not completed properly and the system will not operate properly.

    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 initializing 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.
