Fuel reserve and fuel cap placement warning With the key in steering lock position 2, the fuel reserve warning lamp comes on. It should go out immediately when the engine is running. If the warning lamp does not go out after starting the engine, or if it comes on while driving, it indicates that the fuel level is down to the reserve quantity of approximately 2.1 gal (8 liters). The warning lamp blinks when the fuel cap is not closed, or a fuel system leak has been detected. Retighten cap and see if warning lamp goes out after restart and next OBD selfcheck. If the warning lamp continues to blink after closing the fuel cap correctly, have the fuel system checked at your authorized Mercedes-Benz Center as soon as possible. Leaving the engine running and the fuel cap open can also cause the "CHECK ENGINE" lamp to illuminate, see also page 178. Electronic stability program (ESP) - warning lamp The yellow ESP warning lamp in the speedometer dial comes on with the key in steering lock position 2. It should go out with engine running. See page 170 if the warning lamp lights up or flashes when the vehicle is moving. BAS /ESP malfunction indicator lamp The malfunction indicator lamp for the ESP is combined with that of the BAS. The yellow BAS/ ESP malfunction indicator lamp in the instrument cluster comes on with the key in steering lock position 2. It should go out with the engine running. If the BAS/ ESP malfunction indicator lamp comes on continuously with the engine running, see page 166 and 170.
