IMPORTANT INFORMATION
DPD reduces particulate matter (PM) in the exhaust emissions. The DPD filter
captures PM. When a certain amount of PM has accumulated in the DPD filter, the
filter is automatically regenerated. (The PM is burned away.) To prevent a DPD failure,
be sure to observe the following points:
WARNING
• The DPD and exhaust pipe are extremely hot while the engine is running,
during DPD filter regeneration (PM combustion) and immediately after vehicle
operation. Be careful not to inadvertently touch them. Otherwise, you could be
burned.
• Any dry grass, paper waste or other flammable material near the vehicle could
catch fire.
• Before doing maintenance work on the vehicle, shut down the engine and allow
it to cool down. Otherwise, you could be burned.
ADVICE
• Use Isuzu genuine engine oil compatible with the DPD. Using oil other than
Isuzu genuine engine oil compatible with the DPD would shorten the time
between DPD filter cleaning and could increase fuel consumption.
• Be sure to use extra-low-sulfur diesel fuel (with sulfur content no higher than 10
ppm) or low-sulfur diesel fuel (with sulfur content no higher than 50 ppm).
• If you fill the vehicle with poor-quality fuel, water-removing additive or other
additive, gasoline, kerosene or alcohol-based fuel, it could harm the fuel filter,
prevent proper movement of fuel-lubricated parts in the injectors and adversely
affect engine components, possibly resulting in a breakdown.
• Do not modify the DPD or exhaust pipe.
Changing the alignment, length or diameter of the exhaust pipe would
adversely affect the exhaust system's exhaust emission reduction function. If
any modification is necessary to install a component to the rear of the vehicle,
consult your Isuzu Dealer.
• Although the DPD filter automatically undergoes regeneration (burning of the
accumulated PM) when a certain amount of PM has accumulated, driving
conditions can prevent completion of regeneration. In a model without a multi-
information display (MID), the DPD manual regeneration indicator light will
flash at this time. In a model with a MID, the "PUSH DPD SWITCH" indicator
(amber) will flash. Perform manual regeneration in accordance with the proper
procedure.
This is to restore DPD function and is normal.
