GF40.15-P-2001RTU Detect Seeping Pressure Loss, Function
MODEL 251.1, 164.8
with CODE (470) Tire pressure monitor (base)
with CODE (494) USA version

Function
The "soft warning" operating condition is characterized by a minimum tire pressure at which the vehicle can continue to be driven safely. Via the multifunction display (A1p13) in the instrument cluster (A1) the driver is requested to correct the tire inflation pressure at the next opportunity. A "soft warning" is triggered when the temperature-corrected tire inflation pressure is >0.25 bar lower than the stored nominal pressure.
This first takes place at circuit 15 "ON" and is displayed immediately after the end of the trip. The driver is therefore requested to check the tire inflation pressure and correct if necessary.

Every tire loses air by diffusion over the course of time; this is therefore displayed as a "soft warning".
This timely message to the driver that the tire pressures need to be corrected is a convenience function.
The warning is canceled when filling detection or a manual reactivation is successfully carried out.

Note: If the temperature-corrected tire inflation pressure is >0.5 bar under the stored specified pressure, a "hard warning" ("red" display) is issued.
