Emission Control
Certain systems of the engine
serve to keep certain components
of the exhaust gases within per
missible limits required by law.
These systems, of course, will
function properly only when
maintained strictly according to
factory specifications. Any ad
justments on the engine should,
therefore, be carried out only by
qualified Mercedes-Benz
technicians. The engine should
not be altered in any way. More
over, the specified service and
maintenance jobs must be carried
out regularly according to
Mercedes-Benz servicing re
quirements. For details refer to the
Maintenance 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 con
fined areas (such as a garage)
which are not properly
ventilated. If you think that
exhaust gas fumes are enter
ing 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
500 E (all states); other models
(California version only)
The Continuous Fuel Injection
(CFI) respectively Motronic Multi-
port Fuel Injection (Motronic MFI)
control module control module
monitors emission control compo
nents that either provide input
signals to or receive output signals
from the control module. Malfunc
tions resulting from interruptions
or failure of any of these compo
nents are indicated by the
’’CHECK ENGINE” malfunction
indicator lamp in the instrument
cluster and are simultaneously
stored in the CFI respectively the
Motronic MFI control unit.
If the ’’CHECK ENGINE” malfunc
tion indicator lamp comes on,
have the system checked at your
authorized Mercedes-Benz dealer
as soon as possible.
An on-board diagnostic connector
with pushbutton and light emitting
diode (LED) is located on the
engine compartment firewall,
allowing the accurate identification
of system malfunctions through
the readout of diagnostic trouble
codes.
