OIL CHANGE RESET — IF EQUIPPED
Use this QR code to access your digital
experience.
Your vehicle may be equipped with an
engine oil change indicator 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
indicator 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 place the ignition in the ON/RUN position. To turn
off the message temporarily, push and release the OK
button. To reset the oil change indicator system (after
performing the scheduled maintenance), refer to the
following procedure.
Oil Life Reset
1. Without pushing the brake pedal, place the ignition in the ON/RUN mode (do not start the engine).
2. Navigate to "Oil Life" submenu in "Vehicle Info" in the instrument cluster display.
3. Push and hold the OK button until the gauge resets to
100%. Secondary Method For Oil Change Reset Procedure
1. Without pushing the brake pedal, place the ignition
in the ON/RUN position (do not start the engine).
2. Fully press the accelerator pedal, slowly, three times within ten seconds.
3. Without pushing the brake pedal, place the ignition in the OFF 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.

Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to indicate a
fault in the Forward Collision Warning System.
Contact an authorized dealer for service
Úpage 255.
Service Stop/Start System Warning Light —
If Equipped
This warning light will illuminate when the
Stop/Start system is not functioning properly
and service is required. Contact an authorized
dealer for service.
Cruise Control Fault Warning Light
This warning light will illuminate to indicate the
Cruise Control system is not functioning
properly and service is required. Contact an
authorized dealer.
Sway Bar Fault Warning Light
This light will illuminate when there is a fault in
the sway bar disconnect system Úpage 145.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is
displayed to indicate that the tire pressure is
lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel consumption may not
be guaranteed. Should one or more tires be in the condition previously
mentioned, the display will show the indications
corresponding to each tire.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire pressure
telltale when one or more of your tires is significantly
underinflated. Accordingly, when the low tire pressure
telltale illuminates, you should stop and check your tires
as soon as possible, and inflate them to the proper
pressure. Driving on a significantly under inflated tire
causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability.
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 underinflation has not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
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 upon subsequent
vehicle start-ups 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.
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle, avoid
-
ing sharp braking and steering. If a tire puncture occurs,
repair immediately using the dedicated tire repair kit and
contact an authorized dealer as soon as possible.
CAUTION!
The TPMS has been optimized for the original equip -
ment 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. After -
market wheels can cause sensor damage. Using after -
market tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become inopera -
ble. After using an aftermarket tire sealant it is recom -
mended that you take your vehicle to an authorized
dealer to have your sensor function checked.

130STARTING AND OPERATING
NORMAL STARTING
Observe the instrument cluster lights when starting the
engine.
NOTE:Normal starting of either a cold or a warm engine is
obtained without pumping or pressing 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 illumi -
nated during the preheat process. When the engine Wait
To Start telltale goes off the engine will automatically
crank.
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 ENGINE START/STOP
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.
NORMAL OPERATION — DIESEL ENGINE
Observe the following when the diesel engine is operating:
All message center lights are off.
Malfunction Indicator Light (MIL) is off.
Engine Oil Pressure telltale is not illuminated.
Voltmeter operation.
The voltmeter may show a gauge fluctuation at various
engine temperatures. This is caused by the glow plug
heating system. The number of cycles and the length of
the cycling operation is controlled by the engine control
module. Glow plug heater operation can run for several
minutes. Once the heater operation is complete, the
voltmeter needle will stabilize.
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
Úpage 321.
WARNING!
Do not leave children or animals inside parked vehi -
cles in hot weather. Interior heat buildup may cause
serious injury or death.
When leaving the vehicle, always make sure the
keyless ignition node 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 seri -
ously or fatally injured. Children should be warned
not to touch the parking brake, brake pedal or the
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 ignition of a vehicle equipped with Keyless
Enter ‘n Go™ in the ACC or ON/RUN position. A child
could operate power windows, other controls, or
move the vehicle.

STARTING AND OPERATING131
COLD WEATHER PRECAUTIONS
Operation in ambient temperature below 32°F (0°C) may
require special considerations. The following charts
suggest these options:
Fuel Operating Range
NOTE:Use Ultra Low Sulfur Diesel (ULSD) Fuels ONLY.
Fuel Operating Range Chart
*Number 1 ULSD Fuel should only be used where extended arctic
conditions 0°F (-18°C) exist.
NOTE:
Use of Climatized ULSD Fuel or Number 1 ULSD Fuel
results in a noticeable decrease in fuel economy.
Climatized ULSD Fuel is a blend of Number 2 ULSD
Fuel and Number 1 ULSD Fuel which reduces the
temperature at which wax crystals form in fuel.
The fuel grade should be clearly marked on the pump
at the fuel station.
The engine requires the use of Ultra Low Sulfur Diesel
Fuel . Use of incorrect fuel could result in engine and
exhaust system damage
Úpage 371.
If climatized or Number 1 ULSD Fuel is not available,
and you are operating below 20°F (-6°C), in sustained
arctic conditions, Mopar® Premium Diesel Fuel Treat -
ment (or equivalent) is recommended to avoid gelling
(see Fuel Operating Range Chart).
Engine Oil Usage
See Engine Fluids and Lubricants for the correct engine oil
viscosity Úpage 374.
Winter Front Cover
A Winter front or cold weather cover can be used in
ambient temperatures below 32°F (0°C), especially
during extended idle conditions. This cover is equipped
with four flaps for managing total grille opening in varying
ambient temperatures. If a Winter front or cold weather
cover is to be used, the flaps should be in the full open
position to allow air flow to the cooling module and automatic transmission oil cooler. When ambient
temperatures drop below 0°F (-17°C) the four flaps need
to be closed. A suitable cold weather cover is available
from a Mopar® dealer.
Engine Warm-Up
Avoid full throttle operation when the engine is cold. When
starting a cold engine, bring the engine up to operating
speed slowly to allow the oil pressure to stabilize as the
engine warms up.
If temperatures are below 32°F (0°C), operate the engine
at moderate speeds for five minutes before full loads are
applied.
ENGINE IDLING
Avoid prolonged idling. Long periods of idling may be
harmful to your engine because combustion chamber
temperatures can drop so low that the fuel may not burn
completely. Incomplete combustion allows carbon and
varnish to form on piston rings, cylinder head valves, and
injector nozzles. Also, the unburned fuel can enter the
crankcase, diluting the oil and causing rapid wear to the
engine.

Page 135 of 396
STARTING AND OPERATING133
Do Not Operate The Engine With Failed
Parts
All engine failures give some warning before the parts fail.
Be on the alert for changes in performance, sounds, and
visual evidence that the engine requires service. Some
important clues are:
Engine misfiring or vibrating severely
Sudden loss of power
Unusual engine noises
Fuel, oil or coolant leaks
Sudden change, outside the normal operating range, in
the engine operating temperature
Excessive smoke
Oil pressure drop
ENGINE BREAK-IN RECOMMENDATIONS —
GASOLINE ENGINE (IF EQUIPPED)
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be
detrimental and should be avoided.
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. For the recommended viscosity and quality grades
Úpage 374.
NOTE:A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered a normal part of the break-in and not inter
-
preted as a problem.
ENGINE BREAK-IN RECOMMENDATIONS —
DIESEL ENGINE (IF EQUIPPED)
The diesel engine does not require a break-in period due
to its construction. Normal operation is allowed, providing
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 carrying
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. For
recommended viscosity and quality grades see
Úpage 374. NON-DETERGENT OR STRAIGHT MINERAL
OILS MUST NEVER BE USED.
PARKING BRAKE
Before exiting the vehicle, make sure that the parking
brake is fully applied. Also, be certain to leave an
automatic transmission in PARK, or manual transmission
in REVERSE or FIRST gear.
The parking brake lever is located in the center console.
To apply the parking brake, pull the lever up as firmly as
possible. To release the parking brake, pull the lever up
slightly, push the center button, then lower the lever
completely.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.

2. Remove the fuel cap by rotating it counterclockwise.
Fuel and Diesel Exhaust Fluid (DEF) Fill Location
3. Fully insert the fuel nozzle into the filler pipe.
4. Fill the vehicle with fuel.
NOTE:
When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
Wait five seconds before removing the fuel nozzle
to allow excess fuel to drain from the nozzle.
5. Remove the fuel nozzle, reinstall fuel cap and close fuel filler door.
NOTE:Tighten the fuel filler cap about a quarter turn until you
hear one click. This is an indication that the cap is properly
tightened.
AVOID USING CONTAMINATED FUEL
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system. Proper
maintenance of the engine fuel filter and fuel tank is
essential see
Úpage 321.
BULK FUEL STORAGE — DIESEL FUEL
If you store quantities of fuel, good maintenance 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 system 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 see
Úpage 323.
DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective Catalytic
Reduction (SCR) 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 catalyst 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.
1 — Diesel Fuel Filler
2 — DEF Filler
CAUTION!
For diesel engines, only use diesel fuel for motor
vehicles in accordance with ASTM D-975 Grade S15
specifications. The use of other products or mixtures
may damage the engine beyond repair and
consequently void the warranty, due to the damage
caused. If you accidentally introduce other types of fuel
into the tank, do not start the engine. Empty the tank. If
the engine has been run for even an extremely limited
amount of time, you must not only drain the fuel tank,
but the rest of the supply circuit as well.
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
