BMW X3 Owners Manual: Required tire inflation pressure check message

A Check Control message is displayed in the following situations

• The system has detected a wheel change, but no reset was done.
• Inflation was not carried out according to specifications.
• The tire inflation pressure has fallen below the level of the last confirmation.

  In this case:

• Check the tire pressure and correct as needed.
• Carry out a reset of the system after a tire change.

System limits

The system does not function properly if a reset has not been carried out, e.g., a flat tire is reported though tire inflation pressures are correct.

The tire inflation pressure depends on the tire's temperature. Driving or exposure to the sun will increase the tire's temperature, thus increasing the tire inflation pressure. The tire inflation pressure is reduced when the tire temperature falls again. These circumstances may cause a warning when temperatures fall very sharply.
