malfunction indicator lamp 
comes on while driving.

Such malfunctions may result in excessive 
emissions values and may switch the engine

mode.
Have the vehicle checked as soon as 
possible by an authorized 
Mercedes-Benz Center.

vehicle to the shop diagnostics sys-

the readout of diagnostic trouble

area of the footwell next to the park-
