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
• NOx sensors
• 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.
Adding Diesel Exhaust Fluid
• The DEF gauge (located in the EVIC) will display the level of DEF remaining in the
tank.
• Completely fill the DEF tank through the diesel exhaust fluid fill location (located
behind the fuel door) at every maintenance interval or before if prompted by the
Electronic Vehicle Information Center (EVIC).
NOTE:
Driving conditions (altitude, vehicle speed,
load, etc.) will effect the amount of DEF
that is used in your vehicle.
