Tech Notes for C2224 Subaru

When the low tire pressure warning light illuminates, immediately check the air pressure of all tires and adjust to the specified pressure. After adjusting air pressure, drive the vehicle at 25 mph (40 km/h) or more to start TPM system re-checking of the tire inflation pressures. Warning light should turn off in a few minutes.
If the warning light is still on after adjusting tire pressure, check for a damaged tire and repair as necessary. If warning light blinks 25 times and then illuminates, and there is not a tire without a tire pressure sensor installed, there is a malfunction in the TPM system. See appropriate manufacturer service information.
