ABS/ASC system faults or system statuses are indicated in the instrument cluster with the aid of the ABS safety lamp and the multifunction lamp.
The ABS/ASC system is switched on automatically and then ready for operation every time the ignition is switched on. If the entire system is free of faults, both the ABS safety lamp as well as the multifunction lamp go out after approx. 2 seconds (lamp check).
If the safety circuit detects a fault in the subsystem ABS, the entire system, i.e. ABS and ASC, is switched off (ABS safety lamp and multifunction lamp light up). If the fault no longer occurs during the next starting procedure both lamps go out again after the lamp check.
If the safety circuit detects a fault in the subsystem ASC, either the entire system or the subsystem ASC is switched off depending on the type of fault (ABS safety lamp and/or multifunction lamp light up).
The ASC subsystem can be switched off with the ASC passive button under special driving conditions (e.g. driving off in deep snow). This is indicated by a steady light in the multifunction lamp.
The driver's attention is drawn to an ASC control function by the ASC multifunction lamp flashing while driving (frequency 3 Hz).
Note
During diagnosis (communication with the diagnosis and information system), the ABS safety lamp and the multifunction lamp light constantly.
