System Overview
This vehicle is equipped with a Diesel Exhaust Fluid
(DEF) injection system and a Selective Catalytic Reduc-
tion (SCR) catalyst to meet the emission requirements.
The DEF injection system consists of the following com-
ponents:
•
DEF tank
•
DEF pump
•
DEF injector
•
Electronically-heated DEF lines
•
DEF control module
•
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.
Refer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument Panel” for
system messages and warnings.
NOTE:
The DEF pump will run for a period of time
after engine shutdown to purge the DEF system. This is
normal operation.
