DIESEL PARTICULATE FILTERS (IF EQUIPPED)
This vehicle is equipped with a 2007 emission compliant engine and may be
equipped with an exhaust aftertreatment system which includes a Diesel
Particulate Filter (DPF). The DPF reduces soot and particulate emissions into
the atmosphere. Vehicles equipped with a DPF require the use of EO-O
Premium Plus (or VDS-4) specification high performance diesel engine oil
and Ultra Low Sulfur Diesel (ULSD) fuel.
Use of diesel fuel other than ULSD and engine oils other than EO-O Premium
Plus (or VDS-4), 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 is collected by a filter where it is eventually oxidized
using a regeneration process.
During the regeneration process, the temperature of the exhaust will be
elevated. DO NOT park the vehicle with the exhaust outlet near flammable
objects such as trees, awnings, etc. that could be damaged by elevated exhaust
temperatures.
When regeneration occurs, an indicator lamp on the instrument panel will
illuminate to alert the operator. The vehicle operator can stop or start
regeneration. Certain conditions must be met before a regeneration can be
manually started. Refer to the applicable vehicle operator's manual for a
complete description of DPF indicator lamp and switch functions.
If the vehicle is in a location that may be hazardous when regeneration begins
(i.e., in close proximity to flammable materials or gases, inside tunnels,
parked under flammable objects, etc.), the regeneration should be stopped.
If regeneration is stopped by the vehicle operator, it should be initiated at a
later time when the vehicle is in a safe location. Regenerations that are
stopped and never restarted at a later time, however, will require that the
vehicle be taken to an authorized Volvo Truck dealer to have the regeneration
manually started.
