maintenance JEEP GRAND CHEROKEE 2014 WK2 / 4.G User Guide

The driver’s primary responsibility is the safe operation of the vehicle.
Driving while distracted can result in loss of vehicle control, resulting in
a collision and personal injury. Chrysler Group LLC strongly recommends
that the driver use extreme caution when using any device or feature
that may take their attention off the road. Use of any electrical devices
such as cell phones, computers, portable radios, vehicle navigation or
other devices by the driver while the vehicle is moving is dangerous and
could lead to a serious collision. Texting while driving is also dangerous
and should never be done while the vehicle is moving. If you find yourself
unable to devote your full attention to vehicle operation, pull off the
road to a safe location and stop your vehicle. Some States or Provinces
prohibit the use of cellular telephones or texting while driving. It is
always the driver’s responsibility to comply with all local laws.
Driving after drinking can lead to a collision. Your perceptions are
less sharp, your reflexes are slower, and your judgment is impaired
when you have been drinking. Never drink and then drive.

CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO NOT START the engine
before you drain the water from the fuel filters to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Separator Filter” in “Maintaining
Your Vehicle” in your Diesel Supplement on the DVD for further information.
Extreme Cold Weather
• The engine block heater is a resistance heater installed in the water jacket of the
engine. It requires a 110–115 Volt AC electrical outlet with a grounded, three-wire
extension cord.
• Its use is recommended for environments that routinely fall below -10°F. It should
be used when the vehicle has not been running overnight or longer periods and
should be plugged in two hours prior to start. Its use is required for cold starts with
temperatures under -20°F.
• A 12 Volt heater built into the fuel filter housing aids in preventing fuel gelling. It
is controlled by a built-in thermostat.
• A Diesel Pre-Heat system both improves engine starting and reduces the amount
of white smoke generated by a warming engine.
NOTE:
The engine block heater cord is a factory installed option. If your vehicle is not
equipped, heater cords are available from your authorized MOPAR
®dealer.
Water In Fuel Message
If a Water In Fuel message orindicator appears in the cluster and a chime
sounds five times, the fuel/water separator will need to be drained immediately to
prevent engine damage.
Refer to “Draining Fuel Water Separator” in this guide for draining instructions or see
your dealer.

CAUTION!
• Diesel fuel will damage blacktop paving surfaces. Drain the filter into an
appropriate 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 Electronic Vehicle
Information Center (EVIC).
Perform Service
Your vehicle will require emissions maintenance at a set interval. To help remind you
when this maintenance is due, the Electronic Vehicle Information Center (EVIC) will
display “Perform Service”.
When the “Perform Service” message is displayed on the EVIC it is necessary to have
the emissions maintenance performed.
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.

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 hear
an 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.
Adding Diesel Exhaust Fluid
The DEF gauge (located in the EVIC) will display the level of DEF remaining in the tank.
Completely fill the DEF tank through the diesel exhaust fluid fill location (located
behind the fuel door) at every maintenance interval or before if prompted by the
Electronic Vehicle Information Center (EVIC).
NOTE:
• The gauge may take up to five seconds
to update after adding a gallon or more
of Diesel Exhaust Fluid (DEF) to the
DEF tank. If you have a fault related to
the DEF system, the gauge may not
update to the new level. See your au-
thorized dealer for service.
• The DEF gauge may also not immedi-
ately update after a refill if the tem-
perature of the DEF fluid is below 12°F
(-11°C). The DEF line heater will pos-
sibly warm up the DEF fluid and allow
the gauge to update after a period of
run time. Under very cold conditions, it is possible that the gauge may not reflect
the new fill level for several drives.

Please note that the TPMS is not a substitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct tire pressure, even if under-inflation
has not reached the level to trigger illumination of the TPMS low EVIC display.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate
when the system is not operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute and then remain continuously
illuminated. This sequence will continue each time the vehicle is restarted as long as
the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels allow the TPMS to continue
to function properly.
NOTE:
Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air
temperature change. Keep this in mind when checking tire pressure inside a garage,
especially in the Winter. Example: If garage temperature is 68°F (20°C) and the
outside temperature is 32°F (0°C), then the cold tire inflation pressure should be
increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS
pressures and warning have been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style. Aftermar-
ket wheels can cause sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a TPMS, as damage to the sensors
may result.
- Seat Belt Reminder Light
When the ignition switch is first turned to the ON/RUN position, this light will turn on
for four to eight seconds as a bulb check. During the bulb check, if the driver's seat
belt is unbuckled, a chime will sound. After the bulb check or when driving, if the
driver or front passenger seat belt remains unbuckled, the Seat Belt Indicator Light
will flash or remain on continuously. Refer to “Seat Belts” in “Getting Started” of this
user guide for further information.
WHAT TO DO IN EMERGENCIES
151

- Electronic Throttle Control (ETC) Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system.
If a problem is detected, the light will come on while the engine is running. Cycle the
ignition key when the vehicle has completely stopped and the shift lever/gear selector
is placed in the PARK position; the light should turn off.
If the light remains lit with the engine running, your vehicle will usually be drivable;
however, see an authorized service center immediately. If the light is flashing when the
engine is running, immediate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and your vehicle may require towing.
- Air Bag Warning Light
This light will turn on for four to eight seconds as a bulb check when the ignition
switch is first turned to the ON/RUN position. If the light is either not on during
starting, stays on, or turns on while driving, have the system inspected at an
authorized dealer as soon as possible. Refer to “Occupant Restraints” in “Things To
Know Before Starting Your Vehicle” of your Owner’s Manual for further information.
NOTE:
The Air Bag System is designed to be maintenance free.
Oil Change Indicator

CAUTION!
• Mixing of engine coolant (antifreeze) other than specified Organic Additive
Technology (OAT) engine coolant (antifreeze), may result in engine damage and
may decrease corrosion protection. Organic Additive Technology (OAT) engine
coolant is different and should not be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant (antifreeze) or any “globally compatible”
coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into
the cooling system in an emergency, the cooling system will need to be drained,
flushed, and refilled with fresh OAT coolant (conforming to MS-12106), by an
authorized dealer as soon as possible.
• Do not use water alone or alcohol-based engine coolant (antifreeze) products.
Do not use additional rust inhibitors or antirust products, as they may not be
compatible with the radiator engine coolant and may plug the radiator.
• This vehicle has not been designed for use with propylene glycol-based engine
coolant (antifreeze). Use of propylene glycol-based engine coolant (antifreeze)
is not recommended.
MAINTENANCE SCHEDULE — GASOLINE ENGINE
Your vehicle is equipped with an automatic oil change indicator system. The oil
change indicator system will remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change indicator message will
illuminate. This means that service is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or cold ambient temperatures,
and E85 fuel usage will influence when the “Oil Change Required” message is
displayed. Severe Operating Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km) since last reset. Have your vehicle
serviced as soon as possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator message after completing the
scheduled oil change. If a scheduled oil change is performed by someone other than
your authorized dealer, the message can be reset by referring to the steps described
under “Instrument Cluster Warning Lights” in “What To Do In Emergencies” in this
guide or “Electronic Vehicle Information Center (EVIC)” in “Understanding Your
Instrument Panel” in your Owners Manual on the DVD for further information.
