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
Engine malfunction indicator lamp. If the 
“CHECK ENGINE” malfunction indicator 
lamp comes on when the engine is running, 
it indicates a malfunction of the fuel management 
system, emission control system, systems which impact 
emissions, or the fuel cap is not closed tight (check the 
fuel cap). If the “CHECK ENGINE” lamp is illuminated 
continuously and the vehicle is driving normally, you 
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. See also page 230 for 
fuel cap placement warning.
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.
