INTERVENTION REGENERATION
STRATEGY — MESSAGE PROCESS
FLOW
This engine meets all required diesel engine emissions
standards. To achieve these emissions standards, your
vehicle is equipped with a state-of-the-art engine and
exhaust system. These systems are seamlessly inte-
grated into your vehicle and managed by the Powertrain
Control Module (PCM). The PCM manages engine com-
bustion to allow the exhaust system's catalyst to trap
and burn Particulate Matter (PM) pollutants, with no
input or interaction on your part.
Additionally, your vehicle has the ability to alert you to
additional maintenance required on your vehicle or
engine page 99.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn, such as grass or leaves, and
those items that come into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.

DIESEL EXHAUST FLUID

Diesel Exhaust Fluid (DEF) sometimes known simply by
the name of its active component, UREA—is a key com-
ponent 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 harm-
less nitrogen and water vapor.

ACCESSORY DRIVE BELT
INSPECTION
WARNING!
•
Do not attempt to inspect an accessory drive belt
with vehicle running.
•
When working near the radiator cooling fan, dis-
connect the fan motor lead. The fan is temperature
controlled and can start at any time regardless of
ignition mode. You could be injured by the moving
fan blades.
•
You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If
you have any doubt about your ability to perform a
service job, take your vehicle to a competent
mechanic.
When inspecting accessory drive belts small cracks,
that run across ribbed surface of belt from rib to rib, are
considered normal. This is not a reason to replace the
belt. However, cracks running along a rib (not across)
are not normal. Any belt with cracks running along a rib
must be replaced. In addition, have the belt replaced if
it has excessive wear, frayed cords, or severe glazing.
SERVICING AND MAINTENANCE
Accessory Belt (Serpentine Belt)
Conditions that would require replacement:
•
Rib chunking (one or more ribs has separated from
belt body)
•
Rib or belt wear
•
Longitudinal belt cracking (cracks between two ribs)
•
Belt slips
•
"Groove jumping" (belt does not maintain correct
position on pulley)
•
Belt broken
•
Noise (objectionable squeal, squeak, or rumble is
heard or felt while drive belt is in operation)
NOTE:
Identify and correct problem before new belt is
installed.
Some conditions can be caused by a faulty component
such as a belt pulley. Belt pulleys should be carefully
inspected for damage and proper alignment.
Belt replacement on some models requires the use of
special tools, we recommend having your vehicle ser-
viced at an authorized dealer.
