Description of Emission System
Maintenance Jobs
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
Engine oil and filter change
Change the engine oil and oil filter according
to the specifications outlined in this booklet
for your vehicle If oil consumption should
increase, determine the cause and take
necessary corrective steps Do not reset
the Maintenance System service indicator if
the oil is topped up or changed outside the
respective km interval or 1 year
