Diesel Particulate Filter (Diesel
Engine)
Your vehicle has a Diesel Particulate Filter (DPF) as
part of the exhaust system to reduce vehicle emissions.
The DPF requires a unique exhaust tailpipe with an
exhaust cooler. The exhaust cooler mixes air with the
exhaust at the tailpipe. This lowers the exhaust
temperature before it leaves the tailpipe.
The DPF, the tailpipe, or other exhaust system
components must not be altered. The area where the
exhaust cooler connects to the tailpipe should be
inspected, especially the area where the fresh air enters
the cooler. Make sure the openings are not restricted
or plugged with mud or dirt which could inhibit exhaust
gas cooling. See “Exhaust System Inspection” under
At Least Twice a Year on page 6-27.The DPF will regenerate (self-clean) itself as part of
normal operation. During regeneration, the green DPF
indicator is lit and you will notice a difference in
engine noise and engine speed, but this is normal. The
Engine Control Module (ECM) controls this function
based on several factors including the amount of fuel
consumed, hours of engine operation and miles driven.
Notice:Use of diesel fuel other than Ultra Low
Sulfur Diesel (15 ppm sulfur maximum) or engine oil
other than low ash CJ-4 oil will cause permanent
damage to the DPF and related components.
This damage would not be covered by your
warranty.
Your DPF equipped vehicle has specific fuel and engine
oil requirements. SeeWhat Fuel to Use on page 5-9
andEngine Oil (Caterpillar
®Diesel Engine) on
page 5-23orEngine Oil (Gasoline Engine) on page 5-24
orEngine Oil (DURAMAX
®Diesel Engine) on page 5-28
orEngine Oil (Isuzu Diesel Engine) on page 5-32to
make sure you use the required fuel and engine oil.

{CAUTION:
During DPF regeneration, the exhaust system
and exhaust gases are very hot. Things that
burn could touch hot exhaust parts under your
vehicle and ignite. You or others could be
burned. Do not park near or over papers, leaves,
dry grass, or other things that can burn.
When the yellow DPF indicator comes on, the filter is
dirty and DPF regeneration is necessary. When
driving continues without regeneration, the DPF indicator
will change from yellow to red. Continuing to drive the
vehicle with the red indicator can cause filter damage.
To clean the filter, either drive the vehicle above
30 mph (50 km/h) to activate the automatic regeneration
or stop the vehicle and perform the manual regeneration
procedure. For the automatic regeneration, drive until
the green DPF indicator light goes off. This will take
approximately 20 minutes. Once automatic regeneration
has started, drive until the green indicator light goes
off to complete the regeneration in a single operation if
possible.During regeneration, the
green DPF indicator light
will come on. See
Diesel Particulate Filter
Warning Light on
page 3-45.
Notice:Extended idle should be avoided because
the DPF system is not capable of automatically
regenerating at idle. During extended idle, be sure
to watch for the DPF indicator lights which could
come on to indicate that the DPF is becoming
full and needs regeneration. If the yellow or red
indicator light comes on, perform manual
regeneration or drive the vehicle as described
previously for automatic regeneration to clean the
lter. Continued engine operation with the yellow or
red DPF indicator light on, without performing
manual or automatic regeneration, could cause
irreversible damage to the DPF requiring repair and
possible replacement that might not be covered
by your warranty.
Extended idling can cause exhaust parts and gases to
become very hot. Keep the exhaust area clear of
material that could ignite or burn. SeeParking Over
Things That Burn on page 2-44for more information.

Diesel Particulate Filter
Warning Light
Your vehicle may have
two Diesel Particulate
Filter (DPF) Warning lights.
These lights will come on briefly when the ignition is
turned to ON. One of these lights will come on
green during DPF regeneration. If the other light comes
on yellow, perform a manual regeneration or drive
the vehicle for automatic regeneration. If the light
changes from yellow to red, the DPF requires an
immediate regeneration. If the DPF is not regenerated,
the service engine soon light will come on and engine
power will be reduced.
SeeDiesel Particulate Filter (Diesel Engine) on
page 2-46andReduced Engine Power Light on
page 3-41for more information.
Air Filter Restriction Indicator
If your vehicle has this
feature, the gage is
located above the
switchbank in the center
of the instrument panel.
It monitors the engine
air filter.
As the filter gets dirty, the yellow indicator will begin to
rise. When it reaches the red/orange change area,
the filter should be replaced.
After replacing the filter, reset the gage by pressing in
the yellow reset button at the bottom of the gage.
If you have a Caterpillar
®diesel engine, also see your
Caterpillar®Operation & Maintenance Manual.
