Emission Control
Certain systems of the engine serve to keep the toxic components of the exhaust gases within permissible limits
required by law. These systems, of course, will function properly only when maintained strictly according to factory
specifications. Any adjustments on the engine should, therefore, be carried out only by qualified Mercedes-Benz
authorized dealer technicians. Engine adjustments should not be altered in any way. Moreover, the specified service
jobs must be carried out regularly according to Mercedes-Benz servicing requirements. For details refer to the
Service Booklet.
Warning !
Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide, and
inhaling it can cause unconsciousness and lead to death.
Do not run the engine in confined areas (such as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are entering the vehicle while driving, have the cause determined and
corrected immediately. If you must drive under these conditions, drive only with at least one window fully
open.
On-Board Diagnostic System
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 dealer as soon as possible. With some
exceptions the control module switches off the "CHECK ENGINE" 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.
