OPERATION
395
Use of diesel fuel other than ULSD and engine oils
other than VDS-4 or EO-O Premium Plus, will
adversely affect performance, efficiency and durability
of the DPF system and the engine, to the point where
the engine may not run at all. Manufacturer’s
warranties can also be rendered void due to usage of
improper fuel. Unapproved fuel additives (including
engine oil) are NOT permitted. Blends of No. 1D and
No. 2D grades of ULSD are recommended and
allowable for cold weather operations.
The diesel particulate filter takes the place of the standard muffler.
Soot and other particulate matter are collected by a filter where it is
eventually oxidized using a regeneration process.
During the regeneration process, the temperature
of the exhaust gases will be elevated. DO NOT park
or stop for an extended period under low hanging
overhead flammable objects such as trees,
awnings, structures, etc., that could be damaged
by elevated exhaust temperatures. Further, if the
vehicle is being operated in an area where
flammable vapors exist, the regeneration process
must be interrupted. Failure to heed these
cautions may result in fire or explosion causing
serious personal injury or death.
There are two types of regeneration: at speed automatic and parked.
Automatic regeneration only occurs when the vehicle is moving at
uninterrupted highway speed. Parked regeneration is manually initiated
when the vehicle is stationary. This is the standard configuration. Other
configurations are available.
