Emission Control
Warning!
On-Board Diagnostic System
(California models only)
Certain systems of the engine serve to
keep the toxic components of the
exhaust gases within permissible limits
required by law.
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.
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 unit.
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 technicians.
Engine adjustments should not be
altered in any way. Moreover, the
specified service and maintenance jobs
must be carried out regularly according
to Mercedes-Benz servicing
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.
If the "CHECK ENGINE" malfunction
indicator lamp comes on, have the
system checked at your authorized
Mercedes-Benz dealer as soon as
possible.
requirements. For details refer to the
Maintenance Booklet.
An on-board diagnostic connector

readout of diagnostic trouble codes.

the parking brake pedal.
S 420, S 500 - engine compartment, on
