may still drive the vehicle, however, in all cases, we
recommend that you have the system checked at your
authorized Mercedes-Benz Center as soon as possible.
If the “CHECK ENGINE” lamp comes on continuously
and/or the vehicle is not driving normally (e.g.
malfunction of the fuel management system or running
out of fuel), serious damage can occur to the emission
system. Please contact your authorized Mercedes-Benz
Center immediately.
The Sequential Multiport Fuel Injection (SFI) control
module monitors emission control components that
either provide input signals to or receive output signals
from the control module. Malfunctions resulting from
interruptions or failure of any of these components are
indicated by the “CHECK ENGINE” malfunction
indicator lamp in the instrument cluster and are
simultaneously stored in the SFI control module.
If the “CHECK ENGINE” malfunction indicator lamp
comes on, have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
With some exceptions, the control module switches off
the “CHECK ENGINE” malfunction indicator lamp if the
condition, causing the lamp to come on, no longer exists
during three consecutive cycles.
An on-board diagnostic connector is located in the
passenger compartment near to the parking brake
pedal, allowing the accurate identification of system
malfunctions through the readout of diagnostic trouble
codes.
Notes:
When running out of fuel, the “CHECK ENGINE”
malfunction indicator lamp comes on and the engine
possibly switches to its limp-home (emergency
operation) mode.
To cancel the limp-home mode, the engine may have to
be started three or four times after refueling. The
malfunction indicator lamp remains illuminated. Have
the system checked at your authorized Mercedes-Benz
Center immediately.
