Description
CAUTION
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 exhaust aftertreatment system virtually
eliminates exhaust smoke. Exhaust vapor
(water condensation) may be visible during a
cold start. If exhaust smoke is visible during
engine operation, this indicates a problem
with the exhaust aftertreatment system. Take
the vehicle to an authorized Prevost dealer
immediately
Vehicles equipped with a 2007 emission
compliant engine have an exhaust
aftertreatment system which includes a
Diesel Particulate Filter (DPF). The DPF
reduces soot and particulate emissions into
the atmosphere. The DPF 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. Vehicles equipped
with a DPF require the use of VDS-4 or
EO-O Premium Plus specification high
performance diesel engine oil and Ultra Low
Sulfur Diesel (ULSD) fuel.
Exhaust Aftertreatment System Icons
There are two aftertreatment icons:
•
DPF Regeneration Required
•
High Exhaust System Temperature
(HEST)
The DPF Regeneration Required icon on
the Smart switch illuminates when the
diesel particulate filter is becoming full and
regeneration is needed. The icon flashes
when the filter is full or overfull.

DPF Regeneration Required Icon
The High Exhaust System Temperature
icon in the instrument cluster illuminates
when a parked regeneration is initiated. It
also indicates high exhaust gas temperature
during an at-speed regeneration. When
the HEST icon is illuminated, do not park
or operate the vehicle near people, or any
flammable materials, vapors, or structures.
