2017 JEEP GRAND CHEROKEE engine

NOTE:The system will not automatically sense the pres-
ence of fog, mist or ice on the windshield. Defrost mode
must be manually selected to clear the windshield and side
glass.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Use of the air Recirculation mode during
Winter months is not recommended, because it may cause
window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of service (i.e.,
vacation) for two weeks or more, run the air conditioning system at idle for about five minutes, in fresh air with the
blower setting on high. This will ensure adequate system
lubrication to minimize the possibility of compressor dam-
age when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy
and/or humid weather. To clear the windows, select De-
frost or Mix mode and increase the front blower speed. Do
not use the Recirculation mode without A/C for long
periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
winter months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The climate control system filters out dust and pollen from
the air. Contact your authorized dealer to service your
cabin air filter, and to have it replaced when needed.

2. Reach under the hood, move safety latch to the left andlift the hood.Closing The Hood
1. Hold up the hood with one hand and with the otherhand remove the support rod from its seat and reinsert
it into the locking tab.
2. Lower the hood to approximately 12 inches (30 cm) from the engine compartment and drop it. Make sure that the
hood is completely closed.
WARNING!
Be sure the hood is fully latched before driving your
vehicle. If the hood is not fully latched, it could open
when the vehicle is in motion and block your vision.
Failure to follow this warning could result in serious
injury or death.
CAUTION!
To prevent possible damage, do not slam the hood to
close it. Lower hood to approximately 12 inches (30 cm)
and drop the hood to close. Make sure hood is fully
closed for both latches. Never drive vehicle unless
hood is fully closed, with both latches engaged.

WARNING!
To avoid serious injury or death:
•Only devices designed for use in this type of outlet
should be inserted into any 12 Volt outlet.
• Do not touch with wet hands.
(Continued)
WARNING! (Continued)
•Close the lid when not in use and while driving the
vehicle.
• If this outlet is mishandled, it may cause an electric
shock and failure.
CAUTION!
• Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge suffi-
ciently to degrade battery life and/or prevent the
engine from starting.
• Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.) will degrade the battery
even more quickly. Only use these intermittently and
with greater caution.
• After the use of high power draw accessories, or long
periods of the vehicle not being started (with acces-
sories still plugged in), the vehicle must be driven a
sufficient length of time to allow the generator to
recharge the vehicle’s battery.

Instrument Cluster Descriptions
1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Speedometer •Indicates vehicle speed.
3. Temperature Gauge •The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather or up mountain
grades. It should not be allowed to exceed the upper
limits of the normal operating range.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats.
CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads “H”
pull over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H”, turn the engine off immediately and call an
authorized dealer for service.
4. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
5. Instrument Cluster Display
•The instrument cluster display features a driver-
interactive display. Refer to “Instrument Cluster Dis-
play” in “Getting To Know Your Instrument Panel” for
further information.

Oil Change Reset
Your vehicle is equipped with an engine oil change indi-
cator system. The “Oil Change Required” message will
display in the instrument cluster display for five seconds
after a single chime has sounded, to indicate the next
scheduled oil change interval. The engine oil change indi-
cator system is duty cycle based, which means the engine
oil change interval may fluctuate, dependent upon your
personal driving style.
Unless reset, this message will continue to display each
time you cycle the ignition to the ON/RUN position. To
turn off the message temporarily, push and release theOK
button. To reset the oil change indicator system (after
performing the scheduled maintenance), refer to the fol-
lowing procedure.
Oil Change Reset Procedure
1. Without pushing the brake pedal, push and release the ENGINE START/STOP button and place the ignition to
the ON/RUN position (do not start the engine).
2. Fully push the accelerator pedal, slowly, three times within 10 seconds. 3. Without pushing the brake pedal, push and release the
ENGINE START/STOP button once to return the igni-
tion to the OFF/LOCK position.
NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.
Secondary Method For Oil Change Reset
1. Without pushing the brake pedal, push and release the ENGINE START/STOP button and place the ignition to
the ON/RUN position (do not start the engine).
2. Navigate to Oil Lifesubmenu in Vehicle Info in the
instrument cluster display.
3. Push and hold the OKbutton until the gauge resets to
100%.

Diesel Particulate Filter (DPF) Messages
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 integrated
into your vehicle and managed by the Powertrain Control
Module (PCM). The PCM manages engine combustion to
allow the exhaust system’s catalyst to trap and burn
Particulate Matter (PM) pollutants, with no input or inter-
action on your part.
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 anything that can burn.
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
Instrument Cluster Display:
• Exhaust Filter Nearing Full Safely Drive at Highway
Speeds to Clear — This message will be displayed on
the instrument cluster display if the exhaust particulate
filter reaches 80% of its maximum storage capacity.
Under conditions of exclusive short duration and low
speed driving cycles, your diesel engine and exhaust
after-treatment system may never reach the conditions
required to cleanse the filter to remove the trapped PM.
If this occurs, the “Exhaust Filter XX% Full Safely Drive
at Highway Speeds to Remedy” message will be dis-
played in the instrument cluster display. If this message
is displayed, you will hear one chime to assist in alerting
you of this condition. By simply driving your vehicle at
