avoided. If spilled into a drain, flush
thoroughly with water. For significant
quantities, contact local authorities
for proper disposal procedures.
If DEF is spilled on your vehicle,
rinse with water.
What happens if I ingest DEF?
DEF should never be ingested.
If it is ingested, do not induce
vomiting. A physician should be
consulted if you begin to experience
What happens if I inhale DEF?
While pumping DEF will not cause
significant exposure, inhalation may
occur if exposed to DEF in a closed
area or if DEF is misted into the
air. Under normal conditions of use,
harmful effects are not expected. If
you inhale DEF, you should move
to an area with fresh air and obtain
medical attention if symptoms, such
as irritation to nose and throat,
develop or persist.
Does DEF smell?
DEF may have a slightly pungent
odor similar to that of ammonia,
however it is completely harmless.
Is DEF corrosive?
DEF is corrosive to copper and
brass as well as other materials.
Only approved materials, such as high
density polyethylene (HDPE), will be
used in the DEF tank, packaging and
What happens if a non-DEF
substance is accidentally entered
into the DEF tank?
The SCR system will recognize
solutions other than DEF, and the
DEF indicator light will notify the
driver. Depending on the level of
contamination in the tank, the vehicle
may require servicing.
How much DEF will a truck
DEF consumption is expected
to be about 2 percent of fuel
consumption, depending on vehicle
operation, duty cycle, geography,
load ratings, etc.
What is the number of miles a
truck can expect to travel on
one gallon of DEF?
DEF consumption is directly
related to fuel consumption. A truck
averaging six miles per hour (mpg)
can expect to go about 300 miles on
one gallon of DEF.
Is the DEF dose rate the same for
all engine manufacturers?
The DEF dose rate will vary
slightly among engine manufacturers.
While most engines will have a

dose rate of 2 percent of diesel fuel
consumed, the dose rate will range
from 1 percent to 3 percent.
What happens if the vehicle runs
out of DEF?
Vehicles that use DEF will have
indicators on the dash that will alert
the driver of the quantity of DEF on
board. A gauge similar to a fuel gauge
will indicate the level of DEF. There
will be a DEF low level warning lamp
that will illuminate when DEF is low.
If the vehicle is operated such that
one would run completely out of DEF,
vehicle power will be reduced enough
to encourage the operator to refill the
DEF tank. Once the tank has been
refilled the engine will resume
normal power levels.
