CAUTION
DEF freezing and expansion
DEF will begin to crystallize and freeze at
12°f (-11°c). DEF expands by approximately
7% when frozen. During freezing weather,
do not store a DEF container on the coach
unless it is designed to allow for expansion.
Make sure the DEF container is not
completely full. DEF expansion may split an
inappropriate container, causing a spill and
corrosion as a result.
WARNING
DEF spilt onto hot components will quickly
vaporize. Turn your face away!
Diesel Exhaust Fluid (DEF) 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.
Selective catalytic reduction – Driver warning

SCR system components must not be removed,
altered or modified in any way. In order to
protect the SCR system from tampering,
inducement measures will occur if the following
states are detected:

Disconnection of DEF tank level sensor

Blocked DEF line or dosing valve

Disconnection of DEF dosing valve

Disconnection of DEF pump

Disconnection of SCR wiring harness

Disconnection of NOx sensor

Disconnected exhaust temperature sensor
