System Structure: Indicators
Six indicators are in the gauge assembly: The low pressure indicator, four tire indicators to show which tire is affected, and the TPMS indicator that comes on only if there's problem with the system. When two or more tire pressures are low, the low pressure indicator comes on about 5 seconds before the appropriate tire indicator. Once low pressure is detected, the system scans all four pressure sensors to ensure that it turns on the correct tire indicator.
