System Overview
• This vehicle is equipped with a Diesel Exhaust Fluid (DEF) injection system and
a Selective Catalytic Reduction (SCR) catalyst to meet the emission requirements.
• The DEF injection system consists of the following components:
• DEF tank
• DEF pump
• DEF injector
• Electronically-heated DEF lines
• DEF control module
• NOx sensors
• NH3 sensor
• Temperature sensors
• SCR catalyst
• The DEF injection system and SCR catalyst enable the achievement of diesel
emissions requirements; while maintaining outstanding fuel economy, drivability,
torque and power ratings.
NOTE:
• Your vehicle is equipped with a DEF injection system. You may occasionally hear
an audible clicking noise. This is normal operation.
• The DEF pump will run for a period of time after engine shutdown to purge the DEF
system. This is normal operation.
Diesel Exhaust Fluid Storage
• Diesel Exhaust Fluid (DEF) is considered a very stable product with a long shelf
life. If DEF is kept in temperatures between 10° to 90°F (-12° to 32°C), it will last
a minimum of one year.
• DEF is subject to freezing at the lowest temperatures. For example, DEF may
freeze at temperatures at or below 12° F (-11° C). The system has been designed
to operate in this environment.
NOTE:
When working with DEF, it is important to know that:
• Any containers or parts that come into contact with DEF must be DEF compatible
(plastic or stainless steel). Copper, brass, aluminum, iron or non-stainless steel
should be avoided as they are subject to corrosion by DEF.
• If DEF is spilled, it should be wiped up completely.
