9-10 Technical Information

FUEL TYPE

Your Prevost vehicle is powered by a diesel
engine designed to operate only with Ultra Low
Sulfur Diesel (ULSD) fuel, which can contain no
more than 15 ppm sulfur.
WARNING
ULSD fuel is necessary to avoid fouling the
engine's Exhaust Aftertreatment System. Use of
fuel other than ULSD will reduce the efficiency
and durability of the engine.

BIODIESEL FUEL

Biodiesel with up to a maximum of 5% biofuel
(B5) may be used and will not affect the
manufacturer's mechanical warranty as to engine
and emissions system related components. The
biofuel used in the various blends must conform
to ASTM D6751; therefore B1 to B5 blends
conforming to ASTM D975. Also, any engine
performance problem related to the use of
biodiesel fuel would not be recognized nor
considered as Volvo or Prevost's responsibility.
However, Volvo engines are certified to comply
with U.S. EPA and
standards based upon the use of test fuels with
specifications established by these regulatory
agencies.
Alternative fuels, including biodiesel, that are not
substantially similar to the required test fuels may
adversely affect engine emissions compliance.
As a result, Volvo does not warrant the engine will
conform to applicable Federal or California
emissions limits when operated on biodiesel or
other alternative fuels that are not substantially
similar to specified test fuels used for certification.
Additional maintenance is required and is
covered in Section 03: FUEL SYSTEM of the
maintenance manual.

RECOMMENDED TIRE INFLATION PRESSURE
AT MAXIMUM COLD LOAD
The recommended tire inflation pressures are
given in the applicable documents supplied with
the vehicle. In addition, cold tire inflation
pressures are listed on the Department of
Transport (DOT) certification plate, affixed on the
wall behind the driver's seat.
For special tire selection, a "Prevost coach
special specification" chart is supplied with the
vehicle and is affixed next to the DOT certification
plate.
Vehicles equipped with TPMS: The TPMS target
pressures are factory set to equal the prevailing
tire pressure at delivery time. When tire
pressures are increased to account for higher
vehicle weight, the TPMS set point needs to be
increased accordingly.
NOTE
Before being converted, Bus Shells vehicles
are not at their maximum weight and tire
pressures are adjusted at a lower level value
than the maximum allowed appearing on the
DOT plate. Tire pressure must be readjusted
once converted.
