fuel pump JEEP GRAND CHEROKEE 2016 WK2 / 4.G User Guide

CAUTION!
• Diesel fuel will damage blacktop paving surfaces. Drain the filter into anappropriate container.
• Do not prefill the fuel filter when installing a new fuel filter. There is a
possibility debris could be introduced into the fuel filter during this action. It
is best to install the filter dry and allow the in-tank lift pump to prime the fuel
system.
• If the “Water In Fuel Indicator Light” remains on, DO NOT START the engine
before you drain water from the fuel filter to avoid engine damage.
EXHAUST REGENERATION
This engine meets all required EPA 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 integrated into your vehicle and
managed by the Powertrain Control Module (PCM). Additionally, your vehicle has the
ability to alert you to additional maintenance required on your vehicle or engine.
Refer to the following messages that may be displayed on your Driver Information
Display (DID).
Exhaust System — Regeneration Required Now
This message Indicates that the Diesel Particulate Filter (DPF) reached 80% of its
maximum storage capacity.
By simply driving your vehicle at highway speeds for up to 20 minutes, you can
remedy the condition in the particulate filter system and allow your diesel engine and
exhaust after-treatment system to cleanse the filter to remove the trapped PM and
restore the system to normal operating condition.
Exhaust System — Regeneration in Process Exhaust Filter XX% Full
Indicates that the Diesel Particulate Filter (DPF) is self-cleaning. Maintain your
current driving condition until regeneration is completed.
Exhaust System — Regeneration Completed
This message indicates that the Diesel Particulate Filter (DPF) self-cleaning is
completed. If this message is displayed, you will hear one chime to assist in alerting
you of this condition.

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.
