Instrument cluster with multi-function display

If there are malfunctions (e.g. brake linings worn, coolant level too

low, exterior lamp failure etc.) or system faults (anti-lock brake

system faulty, supplemental restraint system faulty) the warning

display with warning information is inserted in place of outside

temperature, odometer, total mileage recorder and electronic clock.

The warning information is displayed in yellow or red depending on

the fault and a warning tone also sounds.
