Changing Air Filter; Air Filter Restriction Indicator; Diesel Particulate Filter - Monaco 2009 Knight Owner's Manual

The air entering the engine must be as clean
as possible, as contaminated air can cause
destruction of major engine components. Even
small amounts of contaminants can do major
damage to an engine.
INSPECT
The air intake system on a weekly
basis, looking for damage, clogged fins,
loose connections, and wear to the air
ducting, clamps, and filter housing.
Check to ensure that the ducting
is not rubbing or wearing on other
components and that all components
are securely in place. Have any
problems investigated and corrected
as soon as possible in order to prevent
engine damage.

Changing Air Filter

Air Filter Restriction Indicator

The air filter restriction indicator improves
engine efficiency by telling the amount of
restriction present in the air intake system, thus
indicating when the air filter needs changing.
A visual inspection of the air filter is not
adequate and should never dictate service life.
What Indicator Does:
Continuously shows how much life is

left in engine air filter (window).
090504
Continuously reads air flow restrictions

in increments (scale).
When To Monitor:
Inspect indicator before each trip.

When To Change Air Filter:
When the yellow indicator approaches

the red (top) area it is signaling that
the air filter is becoming excessively
dirty. Service the air filter when the red
indicator stays in the window with the
engine off.
Located in rear engine compartment
How To Reset Indicator:

Push button on top to reset.

NOTE
If the air filter restriction indicator
should become faulty, replace entire
unit.

DIESEL pARTIcULATE FILTER

The exhaust system is equipped with a DPF
(Diesel Particulate Filter) to lower particulate
emissions. The DPF traps particulate matter.
Naturally occurring exhaust heat oxidizes
built up particulate and regenerates the
filter. This is called passive regeneration.
If passive regeneration is not sufficient, an
active regeneration cycle will automatically
initiate at speeds greater than 20 mph. Both
passive and active regeneration cycles initiate
automatically.
