Intervention Regeneration Strategy - Message Process Flow (Diesel Engine); Charge Air Cooler - Inter-Cooler (Diesel Engine) - Jeep Grand Cherokee Operating Information Manual

CAUTION!
Due to lack of lubricants in alcohol or gaso-
line, the use of these fuels can cause dam-
age to the fuel system.
NOTE:
• Use of biodiesel mixture in excess of 20%
can negatively impact the fuel filter's abil-
ity to separate water from the fuel, result-
ing in high pressure fuel system corro-
sion or damage.
• In addition, commercially available fuel
additives are not necessary for the proper
operation of your diesel engine.
• For extreme cold conditions, Mopar Pre-
mium Diesel Fuel Treatment is recom-
mended to assist with cold starting.
Intervention Regeneration Strategy
— Message Process Flow (Diesel
Engine)
This engine meets all required diesel engine
emissions standards. To achieve these emis-
sions standards, your vehicle is equipped with a
384
state-of-the-art engine and exhaust system.
These systems are seamlessly integrated into
your vehicle and managed by the Powertrain
Control Module (PCM). The PCM manages
engine combustion to allow the exhaust sys-
tem's catalyst to trap and burn Particulate Mat-
ter (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.
Refer to "Driver Information Display (DID)" in
"Understanding Your Instrument Panel" for fur-
ther information.
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do
not park or operate your vehicle in areas
where your exhaust system can contact any-
thing that can burn.
Charge Air Cooler — Inter-Cooler
(Diesel Engine)
The charge air cooler is positioned in front of the
radiator and the air conditioner condenser. Air
enters the engine through the air cleaner and
passes through the turbocharger, where it is
pressurized. This pressurized air rapidly
reaches high temperature. The air is then di-
rected through a hose to the charge air cooler
and through another hose to the intake manifold
of the engine. This cooling process enables
more efficient burning of fuel resulting in fewer
emissions.
To guarantee optimum performance of the sys-
tem, keep the surfaces of the charge air cooler,
condenser and radiator clean and free of debris.
Periodically check the hoses leading to and
from the charge air cooler for cracks or loose
clamps resulting in loss of pressure and re-
duced engine performance.
