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

Mist
Use the Mist feature when weather conditions make occasional usage of the wipers
necessary. Rotate the end of the lever downward to the Mist position and release for
a single wiping cycle.
NOTE:
The mist feature does not activate the washer pump; therefore, no washer fluid will
be sprayed on the windshield. The wash function must be used in order to spray the
windshield with washer fluid.
Rain Sensing Wipers — If Equipped
This feature senses moisture on the windshield and automatically activates the
wipers for the driver. The feature is especially useful for road splash or overspray from
the windshield washers of the vehicle ahead. Rotate the end of the multifunction
lever to one of four settings to activate this feature.
The sensitivity of the system can be adjusted with the multifunction lever. Wiper
delay position one is the least sensitive, and wiper delay position four is the most
sensitive. Setting three should be used for normal rain conditions. Settings one and
two can be used if the driver desires less wiper sensitivity. Setting four can be used
if the driver desires more sensitivity. Place the wiper switch in the OFF position when
not using the system.
NOTE:
• The Rain Sensing feature will not operate when the wiper switch is in the low orhigh-speed position.
• The Rain Sensing feature may not function properly when ice, or dried salt water is present on the windshield.
• Use of Rain-X or products containing wax or silicone may reduce Rain Sensing performance.
• The Rain Sensing feature can be turned on and off using the Uconnect System, refer to “Uconnect Settings” in “Understanding Your Instrument Panel” in the
Owners Manual on the DVD for further information.

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.
