Fiat Cronos: how to reset the tire pressure from the instrument panel.

After adjusting the tire pressure on the Fiat Cronos, you can store the new values directly from the instrument panel. With the car stationary, engage the parking brake and turn on the ignition without starting the engine, so that the central display between the tachometer and speedometer lights up. On the left side of the steering wheel, you will find a group of buttons with arrows and the OK button, which are used to navigate through the menus.

Use the arrows to scroll through the screens of the onboard computer until you reach the "Vehicle Info" menu. Within this menu, continue scrolling until you find the option for "Tire Pressure," recognizable by the wheel icon and the text on the display that says "Tire Pressure – press OK to reset." At this point, with the option highlighted, press the OK button on the steering wheel and hold it for a few seconds: the system registers the command, and the display shows the confirmation message "Reset stored." Once the operation is complete, you can release the button and return to the normal screens of the onboard computer.

From this moment on, the Fiat Cronos control unit considers the current pressure as the reference value, and the tire pressure monitoring system will only signal any subsequent abnormal variations.
