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
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 requirements. 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 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 im-
mediately. If you must drive under
these conditions, drive only with at
least one window fully open.
On-Board Diagnostic System
(California models only)
The CIS-E control unit monitors
emission control components that
either provide input signals to or
receive output signals from the control
unit. Malfunctions resulting from
interruptions or failure of any of these
components are indicated by the
"CHECK ENGINE" indicator lamp in
the instrument cluster and are
simultaneously stored in the CIS-E
control unit.
If the "CHECK ENGINE" indicator
lamp comes on, have the system
checked at your authorized Mercedes-
Benz dealer as soon as possible.
An on-board test connection with
pushbutton and light emitting diode
(LED) is located on the engine
compartment firewall, allowing the
accurate detection of system
malfunctions.
