WARNING
Please make sure you read the technical documentation, such as the
Operator‘s Manual and workshop information, before carrying out
any maintenance work.
We recommend only the use of Genuine
smart parts for service and repairs, since
they meet our specifications. It is also
important to only use fuels, lubricants and
anticorrosion/antifreeze coolant meeting
factory specifications. Please see your
authorized smart Center for more informa
tion on this subject.
The U.S. Environmental Protection Agency
and, in California, the Air Resources Board
have certified that the emission control
systems of your vehicle comply with the
applicable exhaust emission standards for
MY 2012 vehicles.
To be certain that the emission control
systems function as designed, regular
maintenance is necessary for components
of the vehicle which affect exhaust and
evaporative emissions composition.
The vehicle owner is responsible for the
regular maintenance of the emission con
trol system, as well as the use of premium
unleaded gasoline with an antiknock index
of at least 91 (displayed on the pump) in all
gasoline engine models unless otherwise
specified.
Failure to properly maintain the emission
system may result in repairs not being cov
ered by the emission system warranties.
Explanations of each maintenance job are
given on (

Your smart vehicle is equipped with both a
threeway catalyst and a closed loop
oxygen sensor system to comply with
current exhaust emission regulations. Keep
your vehicle in proper operating condition
by following our recommended maintenance
instructions as outlined.
The following must be adhered to:
a) In all gasoline engine models, use only
premium unleaded gasoline with an anti
knock index of at least 91 (as displayed on
the pump) unless otherwise specified.
Damage to the engine could occur if
premium unleaded fuel is not used. Refer to
the Operator’s Manual for special
precautions.
b) Leaded gasoline should not be used un
der any circumstances.
Damage to the
emission control components will result.
c) The specified engine maintenance jobs
must be performed completely and at the
required intervals.
Properly functioning
spark plugs for instance are important for
the service life of the catalysts. Failure to
properly perform the specified mainte
nance jobs may adversely affect the
emission control system on the vehicle and
reduce its service life.
d) The operation 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 consump
tion, and impaired engine running condi
tions.
e) Irregular engine running conditions
should be corrected immediately by an
authorized smart Center.
Such irregular
running conditions can influence the
proper function of the emission control
system.
If the check engine indicator lamp in the
instrument cluster illuminates when the
engine is running, it indicates a possible
malfunction of the engine management
system or emission control system.
We recommend that you have the
malfunction checked as soon as possible.
