2018 JEEP GRAND CHEROKEE water pump

Mist
Use the Mist feature when weather condi-
tions make occasional usage of the wipers
necessary. Rotate the end of the lever down-
ward 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 func-
tion must be used in order to spray the
windshield with washer fluid.
Rain Sensing Wipers — If Equipped
This feature senses rain or snowfall 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 po-
sition one is the least sensitive, and wiper
delay position four is the most sensitive.NOTE:
Wiper delay position 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 or
high-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 perfor-
mance.
• The Rain Sensing feature can be turned on
and off using the Uconnect System, refer to
“Uconnect Settings” in “Multimedia” in
the Owners Manual for further information.
The Rain Sensing system has protection fea-
tures for the wiper blades and arms, and will
not operate under the following conditions:•Low Ambient Temperature— When the igni-
tion is first turned ON, the Rain Sensing
system will not operate until the wiper
switch is moved, vehicle speed is greater
than 3 mph (5 km/h), or the outside tem-
perature is greater than 32°F (0°C).
•Transmission In NEUTRAL Position— When
the ignition is ON, and the automatic trans-
mission is in the NEUTRAL position, the
Rain Sensing system will not operate until
the wiper switch is moved, vehicle speed is
greater than 3 mph (5 km/h), or the gear
selector is moved out of the NEUTRAL
position.Rear Window Wiper/Washer
The rear wiper/washer controls are located on
the multifunction lever on the left side of the
steering column. The rear wiper/washer is
operated by rotating a switch, located at the
middle of the lever.
Rotate the center portion of the lever upward
to the first detent for intermittent operation
and to the second detent for continuous rear
wiper operation.

Automatic Transmission
Start the engine with the transmission gear
selector in the PARK position. Apply the
brake before shifting to any driving range.
Normal Starting
Observe the instrument panel cluster lights
when starting the engine.
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or press-
ing the accelerator pedal
1. Always apply the parking brake.
2. Press and hold the brake pedal while
pushing the ENGINE START/STOP button
once.
NOTE:
A delay of the start of up to five seconds is
possible under very cold conditions. The
"Wait to Start" telltale will be illuminated
during the pre-heat process, When the
engine Wait To Start light goes off the
engine will automatically crank.
CAUTION!
If the “Water in Fuel Indicator Light” re-
mains on, DO NOT START engine before
you drain the water from the fuel filters to
avoid engine damage. Refer to “Draining
Fuel/Water Separator Filter” in “Servicing
And Maintenance” in your Diesel Supple-
ment for further information, which can be
found with your online Owner’s Informa-
tion.
3. The system will automatically engage the
starter to crank the engine. If the vehicle
fails to start, the starter will disengage
automatically after 25 seconds.
4. If you wish to stop the cranking of the
engine prior to the engine starting, push
the button again.
5. Check that the oil pressure warning light
has turned off.
6. Release the parking brake.
STOP/START SYSTEM — IF
EQUIPPED
The Stop/Start function is developed to re-
duce fuel consumption. The system will stop
the engine automatically during a vehicle
stop if the required conditions are met. Re-
leasing the brake pedal or pressing the accel-
erator pedal will automatically re-start the
engine.
This vehicle has been upgraded with a heavy
duty starter, enhanced battery, and other up-
graded engine parts, to handle the additional
engine starts.
Automatic Mode
The Stop/Start feature is enabled
after every normal customer en-
gine start. At that time, the sys-
tem will go into STOP/START
READY and if all other conditions are met,
can go into a STOP/START AUTOSTOP AC-
TIVE “Autostop” mode.

WARNING!
• Never have any smoking materials lit in
or near the vehicle when the fuel door is
open or the tank is being filled.
• Never add fuel when the engine is run-
ning. This is in violation of most coun-
tries regulations and may cause the
“Malfunction Indicator Light” to turn
on.
• A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always
place fuel containers on the ground
while filling.
CAUTION!
To avoid fuel spillage and overfilling, do
not “top off” the fuel tank after filling.
Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can
cause severe damage to the engine fuel sys-
tem. Proper maintenance of the engine fuelfilter and fuel tank is essential. Refer to
“Dealer Service” in “Servicing And Mainte-
nance” in your Owner’s Manual for further
information.
Bulk Fuel Storage — Diesel Fuel
If you store quantities of fuel, good mainte-
nance of the stored fuel is also essential. Fuel
contaminated with water will promote the
growth of “microbes.” These microbes form
“slime” that will clog the fuel filtration sys-
tem and lines. Drain condensation from the
supply tank and change the line filter on a
regular basis.
NOTE:
When a diesel engine is allowed to run out of
fuel, air is pulled into the fuel system.
If the vehicle will not start, refer to “Dealer
Service / Priming If The Engine Has Run Out
Of Fuel” in “Servicing And Maintenance” in
your Owner’s Manual for further information.
WARNING!
Do not open the high pressure fuel system
with the engine running. Engine operation
WARNING!
causes high fuel pressure. High pressure
fuel spray can cause serious injury or
death.
Diesel Exhaust Fluid
Your vehicle is equipped with a Selective
Catalytic Reduction system to meet the very
stringent diesel emissions standards required
by the Environmental Protection Agency.
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 a near-zero level. A small
quantity of Diesel Exhaust Fluid (DEF) is
injected into the exhaust upstream of a cata-
lyst where, when vaporized, it converts 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.

CAUTION!
•To avoid DEF spillage, and possible dam-
age to the DEF tank from overfilling, do
not “top off” the DEF tank after filling.
• DO NOT OVERFILL. DEF will freeze be-
low 12ºF (-11ºC). The DEF system is
designed to work in temperatures below
the DEF freezing point, however, if the
tank is overfilled and freezes, the system
could be damaged.
• When DEF is spilled, clean the area
immediately with water and use an ab-
sorbent material to soak up the spills on
the ground.
• Do not attempt to start your engine if
DEF is accidentally added to the diesel
fuel tank as it can result in severe dam-
age to your engine, including but not
limited to failure of the fuel pump and
injectors.
CAUTION!
• Never add anything other than DEF to
the tank – especially any form of hydro-
carbon such as diesel fuel, fuel system
additives, gasoline, or any other
petroleum-based product. Even a very
small amount of these, less than
100 parts per million or less than 1 oz.
(30 ml) per 78 gallons (295 liters) will
contaminate the entire DEF system and
will require replacement. If owners use a
container, funnel or nozzle when refilling
the tank, it should either be new or one
that is has only been used for adding
DEF. Mopar provides an attachable
nozzle with its DEF for this purpose.3. Stop filling the DEF tank immediately
when any of the following happen: DEF
stops flowing from the fill bottle into the
DEF fill inlet, DEF splashes out the fill
inlet, or a DEF pump nozzle automatically
shuts off.
4. Reinstall cap onto DEF fill inlet.
