DIESEL EXHAUST FLUID
Diesel Exhaust Fluid (DEF) sometimes known simply by the name of its active
component, UREA – is a key component of selective catalytic reduction (SCR)
systems, which help diesel vehicles meet stringent emission regulations. DEF is a
liquid reducing agent that reacts with engine exhaust in the presence of a catalyst to
convert smog-forming nitrogen oxides (NOx) into harmless nitrogen and water vapor.
Your vehicle is equipped with a Selective Catalytic Reduction system in order to meet
the very stringent diesel emissions standards required by the Environmental Protec-
tion Agency. Selective Catalytic Reduction (SCR) is the first and only technology in
decades to be as good for the environment as it is good for business and vehicle
performance.
The purpose of the SCR system is to reduce levels of NOx (oxides of nitrogen emitted
from engines) that are harmful to our health and the environment to an almost near-zero
level. Small quantities of Diesel Exhaust Fluid (DEF) are injected into the exhaust
upstream of a catalyst where, when vaporized, convert 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 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 hearan 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.

- Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of an onboard diagnostic system called
OBD II that monitors engine and automatic transmission control systems. The light
will illuminate when the key is in the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF to ON/RUN, have the condition
checked promptly.
Certain conditions, poor fuel quality, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through several of your typical driving
cycles. In most situations, the vehicle will drive normally and will not require towing.
CAUTION!
Prolonged driving with the Malfunction Indicator Light (MIL) on could cause damage
to the engine control system. It also could affect fuel economy and driveability. If the
MIL is flashing, severe catalytic converter damage and power loss will soon occur.
Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced above, can reach higher tempera-
tures than in normal operating conditions. This can cause a fire if you drive slowly or
park over flammable substances such as dry plants, wood, cardboard, etc. This could
result in death or serious injury to the driver, occupants or others.
- Electronic Stability Control (ESC) OFF Indicator Light
The ESC OFF indicator will illuminate when the Electronic Stability Control (ESC) is
turned off.
- Charging System Light
This light shows the status of the electrical charging system. If the charging system light
remains on, it means that the vehicle is experiencing a problem with the charging
system.
We recommend you do not continue driving if the charging system light is on. Have
the vehicle serviced immediately.
- Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as possible. A chime will sound for four
minutes when this light turns on.
We recommend you do not operate the vehicle or engine damage will occur. Have the
vehicle serviced immediately.
