Your Mercedes-Benz vehicle is equipped with
both a three-way catalyst and a closed loop
oxygen sensor system to comply with current
exhaust emission regulations. eep your
vehicle in proper operating condition by fol-
lowing our recommended maintenance
instructions as outlined.
The following must be adhered to:
a In all asoline en ine models use only
remium unleaded asoline with an anti-
noc inde of at least
on the um unless otherwise s ecified
Damage to the engine could occur if premium
unleaded fuel is not used. Refer to the Oper-
ator's Manual for special precautions.
b Leaded asoline should not be used
under any circumstances Damage to the
emission control components will result.
c In non fle ‑fuel ca able asoline en ine
e ui ed vehicles ethanol blends
reater than E should not be used
Damage to the engine could occur if improper
fuels are used. Refer to the Operator's Man-
ual for special precautions.
d The s ecified en ine maintenance obs
must be erformed com letely and at the
re uired intervals Properly functioning
spark plugs for instance are important for the
service life of the catalysts. Failure to properly
perform the specified maintenance jobs may
adversely affect the emission control system
on the vehicle and reduce its service life.

WARNING
e The o eration of the emission control
system must not be altered in any way
Alterations are not permissible by law. In
addition, alterations may result in damage to
the catalysts, increased fuel consumption,
and impaired engine running conditions.
f Irre ular en ine runnin conditions
should be corrected immediately by an
authorized Mercedes-Benz enter Such
irregular running conditions can influence the
proper function of the emission control sys-
tem.
If the check engine indicator lamp in the
instrument cluster illuminates when the
engine is running, it indicates a possible mal-
function of the engine management system
or emission control system.
We recommend that you have the malfunc-
tion checked as soon as possible.
escri tion of Emission System Main-
as dis layed
tenance obs
The composition of exhaust emissions is
influenced not only by the special emission
control equipment, but also by various engine
components and their adjustments.
Therefore, emission system maintenance
must include these engine components.
Some maintenance jobs are actually only
tests. They are important however, because
they allow early detection of discrepancies
which can later lead to increased exhaust
emissions. It is generally less expensive to
have such items adjusted immediately rather
than allowing them to contribute to costly
repairs. The maintenance intervals have been
determined so that the vehicle, under normal
conditions, should operate properly between
services.
Please make sure you read the technical documentation, such as
the Operator's Manual and workshop information, before carrying
out any maintenance work.
