Instruments and controls Operation Driving Instrument cluster display Practical hints Car care Technical data Index Malfunction and indicator lamps ABS malfunction indicator lamp The ABS malfunction indicator lamp in the instrument cluster comes on with the electronic key in starter switch position 2 and should go out with the engine running. ABS 272 With the ABS malfunctioning, the BAS and ESP are also switched off. The malfunction indicator lamps and malfunction messages in the multifunction display come on with the engine running. If the charging voltage falls below 10 volts, the malfunction indicator lamp comes on and the ABS is switched off. When the voltage is above this value again, the malfunction indicator lamp should go out and the ABS is operational. Have the system checked at your authorized Mercedes-Benz Center as soon as possible. See page 258 for notes on antilock brake system (ABS). When the ABS malfunction indicator lamp symbol and warning in the instrument cluster remains illuminated while the engine is running, it indicates that the ABS has detected a malfunction and has switched off. In this case, the brake system functions in the usual manner, but without antilock assistance. A malfunctioning ABS control unit can possibly affect the operation of other systems (e.g. Navigation, Automatic transmission). Be guided accordingly with respect to the use of those systems and have the system checked at your authorized Mercedes-Benz Center as soon as possible.
