indicator system. The “Oil Change Required” message
will display in the EVIC after a single chime has sounded,
to indicate the next scheduled oil change interval. The
engine oil change indicator system is duty cycle based,

Low Diesel Exhaust Fluid Light
This telltale will turn on to indicate the Diesel
Exhaust Fluid (DEF) is low.Diesel Particulate Filter (DPF) Messages
The diesel engine meets all EPA Heavy Duty Diesel
Engine Emissions Standards, resulting in one of the
lowest emitting diesel engines ever produced. To achieve
these emissions standards, your vehicle is equipped with
a state-of-the-art engine and exhaust system. These sys-
tems are seamlessly integrated into your vehicle and
managed by the Powertrain Control Module (PCM). The
PCM manages engine combustion to allow the exhaust
system’s catalyst to trap and burn Particulate Matter
(PM) pollutants, with no input or interaction on your
part.

CAUTION!
See your authorized dealer, as damage to the exhaust
system could occur soon with continued operation.

the vehicle detects that the DEF system has been filled
with a fluid other than DEF, has experienced component
failures, or when tampering has been detected. The
vehicle may be limited to a maximum speed of 5 MPH (8
km/H) if the DEF system is not serviced within less than
200 miles (322 km) of the fault being detected.
When the DEF system needs to be serviced the following
warnings will display:
•Service DEF System See Dealer — This message will
display when the fault is initially detected, each time
the vehicle is started, and periodically during driving.

DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective Catalytic Re-
duction system to meet the very stringent diesel emis-
sions standards required by the Environmental Protec-
tion Agency.
The purpose of the SCR system is to reduce levels of NOx
(oxides of nitrogen emitted from engines) that are harm-
ful to our health and the environment to a near-zero level.
Small quantities of Diesel Exhaust Fluid (DEF) is injected
into the exhaust upstream of a catalyst where, when
vaporized, it converts smog-forming nitrogen oxides
(NOx) into harmless nitrogen (N2) and water vapor
(H2O), two natural components of the air we breathe.
You can operate with the comfort that your vehicle is
contributing to a cleaner, healthier world environment
for this and generations to come.
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
• NOx sensors
• Temperature sensors
• SCR catalyst
