Malfunction and indicator lamps
in the instrument cluster
General information:
If a bulb in the instrument cluster fails to light up
during the bulb self-check when turning the electronic
key in steering lock to position 2, have it checked and
replaced if necessary.
On-board diagnostic system
Check engine malfunction indicator lamp
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 the engine hood release,
allowing the accurate identification of system
malfunctions through the readout of diagnostic trouble
codes.
Brake warning lamp
Except Canada
Canada only
With the key in steering lock position 2, the brake
warning lamp will come on. It should go out when the
engine is running.
