With operating faults warning messages are faded in the multifunction display. The warning messages are faded in below the electronic speedometer with the respective symbol. These warning messages are divided up into the following priorities:

Priority 1
Warning messages with high priority
Priority 2
Warning messages with low priority

Priority 1, warning messages with high priority

These warning messages cannot be acknowledged sometimes. When they occur the fault is shown in the multifunction display. New warning messages with the same priority are faded in automatically as soon as the previous warning message was displayed for 5 s. The display changes between the warning messages every 5 s. Any priority 2 warning messages are cross-faded.

Priority 2, warning messages with low priority

If a priority 1 warning message is present, the priority 2 warning message is not displayed until the priority 1 warning message has been acknowledged or the fault is no longer present. New warning messages with the same priority are faded in automatically as soon as the previous warning message was displayed for 5 s. The display changes between the warning messages every 5 s.

Most warning messages can be acknowledged with the OK button (S110s6) of the left multifunction steering wheel button group (S110)

In addition to the display of warning messages in the multifunction display warning lamps or indicator lamps are actuated for some faults. These lightup as long as the fault is present and, like most warning messages, cannot be acknowledged in the multifunction display.

Displaying warning and fault messages

Except for a few exceptions fault messages are first displayed when the engine is running. Current fault messages are faded in immediately.

A warning chime sounds simultaneously for many of the warning messages.

Reminder about faults at the end of a trip

With "circuit 15 OFF" the faults are stored in an error list and a displayed again as a reminder.

Example of display priority

Three of the many possible messages are shown below with a short description.

The sequence in which messages are displayed in the case of several faults is explained using an example:

If the washer fluid level is too low a priority 2 message which calls up refilling the washer fluid is shown in the multifunction display.
If the coolant level is also too low as well, the priority 2 message which calls up checking the coolant level is also displayed. The display now changes every 5 seconds between this message and the message which calls up the refilling of washer fluid as 2 messages of the same priority exist.
If now in addition a fault in the level control occurs the priority 1 message which requests stopping the vehicle is displayed. This message cross-fades the two priority 2 messages due to its higher priority.

The example is based on the assumption that none of the messages is acknowledged and canceled.
