2015 JEEP GRAND CHEROKEE transmission

A MESSAGE FROM FCA US LLC
FCA US LLC welcomes you as a turbocharged diesel-
powered vehicle owner. Your diesel vehicle will sound,
feel, drive and operate differently from a gasoline-
powered vehicle. It is important that you read and
understand this manual.
Almost 100% of the heavy trucks in the United States and
Canada are diesel-powered because of the fuel economy,
rugged durability, and high torque which permits pulling
heavy loads.
You may find that some of the starting, operating, and
maintenance procedures are different. However, they are
simple to follow and careful adherence to them will
ensure that you take full advantage of the features of this
engine.NOTE:
•Some aftermarket products may cause severe engine/
transmission and/or exhaust system damage. Your
vehicle’s powertrain control systems can detect and
store information about vehicle modifications that
increase horsepower and torque output such as
whether or not performance-enhancing powertrain
components, commonly referred to as downloaders,
power boxes, or performance chips have been used.
•Any chassis/suspension or tire size modifications to
the vehicle will effect the performance of the Adaptive
Cruise Control and Forward Collision Warning Sys-
tem.
4 INTRODUCTION

REMOTE STARTING SYSTEM
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
approximately 300 ft (91 m).
NOTE:
•The vehicle must be equipped with an automatic
transmission to be equipped with Remote Start.
•Obstructions between the vehicle and the RKE trans-
mitter may reduce this range.•The Remote Start system will wait for the “Wait To
Start” amber telltale to extinguish before cranking the
engine. This allows time for the engine pre-heat cycle
to pre-heat the cylinder air, and is normal in cold
weather. Refer to “Electronic Vehicle Information Dis-
play (EVIC)” in “Understanding Your Instrument
Panel” for further information on the “Wait To Start”
amber telltale and the pre-heat cycle.
How To Use Remote Start
All of the following conditions must be met before the
engine will remote start:
•Shift lever in PARK
•Doors closed
•Hood closed
•HAZARD switch off
•BRAKE switch inactive (brake pedal not pressed)
8 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due
to its construction. Normal operation is allowed, provid-
ing the following recommendations are followed:
•Warm up the engine before placing it under load.
•Do not operate the engine at idle for prolonged
periods.
•Use the appropriate transmission gear to prevent
engine lugging.
•Observe vehicle oil pressure and temperature indica-
tors.
•Check the coolant and oil levels frequently.
•Vary throttle position at highway speeds when carry-
ing or towing significant weight.NOTE:Light duty operation such as light trailer towing
or no load operation will extend the time before the
engine is at full efficiency. Reduced fuel economy and
power may be seen at this time.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown under “Fluids, Lubricants and Genuine Parts”,
under “Maintaining Your Vehicle” in this manual. NON-
DETERGENT OR STRAIGHT MINERAL OILS MUST
NEVER BE USED.
10 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

4. High Beam Indicator
Indicates that headlights are on high beam.
5. Front Fog Light Indicator — If Equipped
This indicator will illuminate when the front fog
lights are on.
6. LH Selectable DID
This area of the cluster will display selectable informa-
tion such as compass, outside temperature, etc. For
further information, refer to “Driver Information Display
(DID)” in this section.
7. Turn Signal Indicator
The arrows will flash with the exterior turn sig-
nals when the turn signal lever is operated. A tone
will chime, and a DID message will appear if either turn
signal is left on for more than 1 mile (1.6 km).NOTE:If either indicator flashes at a rapid rate, check
for a defective outside light bulb.
8. Speedometer
Indicates vehicle speed.
9. RH Selectable DID
This area of the cluster will display selectable informa-
tion such as compass, outside temperature, etc. For
further information, refer to “Driver Information Display
(DID)” in this section.
10. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system called OBD II that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in
the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF to
ON/RUN, have the condition checked promptly.

CAUTION!
•The engine is allowed to crank as long as 30
seconds. If the engine fails to start during this
period, please wait at least two minutes for the
starter to cool before repeating start procedure.
•If the “Water in Fuel Indicator Light” remains on,
DO NOT START 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” for
further information.
Automatic Transmission
Start the engine with the transmission gear selector in the
PARK position. Apply the brake before shifting to any
driving range.
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 exten-
sion cord. Its use is recommended for environments that
routinely fall below -10°F (-23°C). 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 (-28°C).
NOTE: The engine block heater cord is a factory in-
stalled option. If your vehicle is not equipped, heater
cords are available from your authorized MOPAR®
dealer.
•A 12 Volt heater built into the fuel filter housing aids in
preventing fuel gelling. It is controlled by a built-in
thermostat.
38 STARTING AND OPERATING

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.
Starting Fluids
The engine is equipped with a glow plug preheating
system. If the instructions in this manual are followed,
the engine should start in all conditions and no type of
starting fluid should be used.
WARNING!
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
(Continued)
WARNING!(Continued)
•When leaving the vehicle, always make sure the
ignition is in the OFF position, remove the key fob
from the vehicle, and lock the vehicle.
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the transmission gear selector. Do not leave the
key fob in or near the vehicle (or in a location
accessible to children), and do not leave the igni-
tion (of a vehicle equipped with Keyless Enter-N-
Go™) in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move
the vehicle.
40 STARTING AND OPERATING

NOTE:Under certain conditions the engine fan will run
after the engine is turned off. These conditions are under
high load and high temperature conditions.
Cooling System Tips — Automatic Transmission
To reduce the potential for engine and transmission
overheating in high ambient temperature conditions,
take the following actions:
•City Driving — When stopped, shift the transmission
into NEUTRAL and increase engine idle speed.
•Highway Driving — Reduce your speed.
•Up Steep Hills — Select a lower transmission gear.
•Air Conditioning — Turn it off temporarily.
NOTE:If the coolant temperature is too high the A/C
will automatically turn off.
Do Not Operate The Engine With Low Oil
Pressure
If the low oil pressure warning light turns on while
driving, stop the vehicle and shut down the engine as
soon as possible. A chime will sound when the light turns
on.
NOTE:Do not operate the vehicle until the cause is
corrected. This light does not show how much oil is in the
engine. The engine oil level must be checked under the
hood.
CAUTION!
If oil pressure falls to less than normal readings, shut
the engine off immediately. Failure to do so could
result in immediate and severe engine damage.
