Tire Pressure Monitoring System (TPMS) with Location and Pressure Indicators

ILX 2020 tire pressure information shown in the Multi-Information Display

An under-inflated tire impedes handling and can be a safety hazard. To prevent this, the Tire Pressure Monitoring System (TPMS) uses a sensor to determine if a tire’s pressure is significantly below the recommended level.


  • Pressure sensors in each wheel send readings to a central electronic control unit that evaluates whether the pressure is acceptable. If a reading is significantly below the recommended level, the system alerts you on the Multi-Information Display (MID). The problematic tire, along with the individual pressure for all four tires, is indicated.

  • While useful, it’s still recommended you manually check your tires on a regular basis.
