Driver Warning And Inducement Measures - PREVOST H3-45 2023 Operator's Manual

Diesel Exhaust Fluid Consumption
DEF consumption is related to fuel consumption.
In order to meet EPA requirements, DEF tanks
are sized so one refill will be necessary every two
refill of the fuel tank.
DRIVER WARNING AND INDUCEMENT
MEASURES
Auxiliary Emission Control Device (EACD)
defines as any element of design which senses
temperature, vehicle
transmission gear, manifold vacuum, or any other
parameter for the
modulating, delaying,
operation of any part of the emission control
system.
Disconnection of the following EACD produces
immediate activation of the Malfunction Indicator
Lamp MIL and 25% engine derate after three (3)
hours of a continuous open circuit condition.
