After the ignition starter switch has been switched to ON, the first display to appear on the display screen is the standby screen with the marque logo. If a fault occurs at this point, a corresponding fault alert will be displayed. If no fault occurs, the system checks whether there are any event notifications present. If there are, the associated pop-up window opens and the driver has to acknowledge the event no-
tifications in order of their urgency. The system then verifies whether the supply pressures for the various compressed-air circuits are at acceptable levels. If so, the bus graphic in the “Vehicle” main menu is then displayed. However, if a supply pressure is too low, which may be the case if the vehicle has been parked up for a long period, a pop-up window displaying the supply pressures for the various compressed-air circuits opens (see illustration). The pop-up window closes automatically as soon as the necessary operating pressure is reached. If the driver acknowledges the pop-up window using the main menu buttons on the steering wheel before the correct pressure has been reached, another pop-up window opens and displays a red alert informing the driver once more that the operating pressure is still too low. If the necessary operating pressure is now reached, or if the driver acknowledges the red alert, the bus graphic in the “Vehicle” main menu will be displayed.
