Emission Control
Certain systems of the engine serve to
keep the toxic components of the ex­
haust gases within permissible limits
required by law.
These systems, of course, will func­
tion properly only when maintained
strictly according to factory specifica­
tions. Any adjustments on the engine
should, therefore, be carried out only
by qualified MERCEDES-BENZ tech­
nicians. The adjustments of the engine
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 de­
tails refer to the Maintenance Booklet.
Warning!
Inhalation of exhaust gas is haz­
ardous to your health. All exhaust
gas contains carbon monoxide, and
inhaling it can cause unconscious­
ness 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 fum es are entering
the vehicle while driving, have the
cause determ ined and corrected
immediately. If you must drive un­
der these conditions, drive only
with at least one window fully open.
On-Board Diagnostic System
(California models only)
The CIS-E control unit monitors em is­
sion control components that either
provide input signals to or receive
output signals from the control unit.
Malfunctions resulting from interrup­
tions or failure of any of these compo­
nents are indicated by the “ CHECK
ENGINE” indicator lamp in the instru­
ment 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 at the first
opportunity.
An on-board test connection with
pushbutton and light emitting diode
(LED) is located on the engine com ­
partment firewall, allowing the accu­
rate detection of system malfunctions.
