Isuzu N Series 2008 Owner's Manual page 91

NOTE
• If the vehicle is stationary with the engine idling during DPD regeneration, the
exhaust brake or exhaust throttle operates. Operating sounds will be heard
when the exhaust brake or exhaust throttle is activated or deactivated. The
sounds do not indicate a fault.
• Combustion of PM during DPD regeneration can cause white smoke to be
briefly emitted from the exhaust pipe. The white smoke does not indicate a fault.
Do not perform manual regeneration in any poorly ventilated indoor place.
• When a new vehicle has been driven a certain distance, it can emit white smoke
during DPD regeneration. The white smoke does not indicate a fault. The
vehicle may not emit white smoke during its initial operation when new.
• Owing to the exhaust emission reduction function, the exhaust gases emitted
by the exhaust pipe smell different from those emitted by the exhaust pipes of
earlier diesel vehicles.
• The exhaust brake may automatically be activated in order to prevent emission
of white smoke if the engine idles continuously over an extended period of time.
