Emission System Maintenance
General
The U.S. Environmental Protection Agen-
cy 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 2008 vehicles. This ve-
hicle also complies with the applicable
Canadian Motor Vehicle Emission Stand-
ards.
To be certain that the emission control
systems function as designed, regular
maintenance is necessary for compo-
nents of the vehicle which affect exhaust
and evaporation emissions composition.
The vehicle owner is responsible for the
regular maintenance of the emission con-
trol system, as well as the use of premi-
um unleaded gasoline with an anti-knock
index of at least 91 (displayed on the
pump) in all gasoline engine models un-
less otherwise specified.
Failure to properly maintain the emission
system may result in repairs not being
covered by the emission system warran-
ties.
Explanations of each maintenance job
are given in numerical order on page 66.
