Warning Light Functions, Overview


Warning light functions, overview
- If On Board Diagnostic (OBD) has detected a malfunction in the system, it indicates the malfunction by lighting up warning lamps when ignition is switched on. The warning lamps are located in the instrument cluster.





Instrument cluster without DIS
- The illustration shows the ABS/EDL warning light -K47- (right arrow), the warning light for brake system -K118(center arrow, red symbol for "brake system malfunction") and the traction control indicator light -K86- (left arrow).





Instrument cluster with DIS
- For DIS, there is no warning light for brake system -K118-. The red "brake system malfunction" symbol appears in the display.
- If the ABS/EDL warning light -K47 and the red symbol for "Brake system malfunction" are not lit, but the brake system is not functioning properly, check for malfunctions in the mechanical/hydraulic brake system components.
