Winter Front Cover

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, turbochargers,
and injector nozzles. Also, the unburned fuel can
enter the crankcase, diluting the oil and causing
rapid wear to the engine.

STARTING AND OPERATING149
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. After the vehicle is safely
stopped, restart the engine and monitor the lamp.
If the lamp is still illuminated, shut the engine off,
contact an authorized dealer, and do not operate
the vehicle until the cause is corrected. If the lamp
is no longer illuminated, the engine can be
operated, but should be taken to an authorized
dealer as soon as possible for further inspection.
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.
Do Not Operate The Engine With Failed
Parts
All engine failures give some warning before the
parts fail. Some important observations 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 BLOCK HEATER — IF EQUIPPED

Engine Block Heater Cord Location
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the
heater cord to a ground-fault interrupter protected
110–115 Volt AC electrical outlet with a grounded,
three-wire extension cord.
For diesel engines, 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 for long periods of time and should
be plugged in two hours prior to start. Its use is
required for cold starts with temperatures under
-20°F (-28°C).
To ensure reliable starting at these temperatures,
use of an externally powered electric engine block
heater (available from an authorized dealer) is
recommended.
The engine block heater cord is routed under the
hood on the passenger side of the vehicle next to
the engine coolant reservoir.
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.WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.

150STARTING AND OPERATING
ENGINE BREAK-IN RECOMMENDATIONS —
GASOLINE ENGINE
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 Ú page 473.
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 interpreted as a problem. Please check
your oil level with the engine oil indicator often
during the break-in period. Add oil as required.
ENGINE BREAK-IN RECOMMENDATIONS —
DIESEL ENGINE
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.
Observe vehicle oil pressure and temperature
indicators.
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 the recommended viscosity and
quality grades Ú
page 473.
NOTE:NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.
PARKING BRAKE
ELECTRIC PARK BRAKE (EPB)
Your vehicle is equipped with an EPB that offers
simple operation, and some additional features
that make the parking brake more convenient and
useful.
The parking brake is primarily intended to prevent
the vehicle from rolling while parked. Before
leaving the vehicle, make sure that the parking
brake is applied. Also, be certain to leave the
transmission in PARK.
You can engage the parking brake in two ways:
Manually, by applying the parking brake switch.
Automatically, by enabling the Auto Park Brake
feature in the Customer Programmable
Features section of the Uconnect settings.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.

158STARTING AND OPERATING
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest upshifts
and downshifts, and the best fuel economy. The
transmission automatically upshifts through all
forward gears.
When frequent transmission shifting occurs (such
as when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong
head winds, or while towing a heavy trailer), select
TOW/HAUL mode or use the Electronic Range
Select (ERS) shift control to select a lower gear
range Úpage 158. Under these conditions, using
a lower gear range will improve performance and
extend transmission life by reducing excessive
shifting and heat buildup.
During extremely cold temperatures (-22°F
[-30°C] or below), transmission operation may be
modified depending on engine and transmission
temperature as well as vehicle speed. Normal
operation will resume once the transmission
temperature has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically
for abnormal conditions. If a condition is detected
that could result in transmission damage,
Transmission Limp Home Mode is activated. In this
mode, the transmission may operate only in
certain gears, or may not shift at all. Vehicle performance may be severely degraded
and the engine may stall. In some situations, the
transmission may not re-engage if the engine is
turned off and restarted. The Malfunction Indicator
Light (MIL) may be illuminated. A message in the
instrument cluster will inform the driver of the
more serious conditions, and indicate what actions
may be necessary.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
NOTE:In cases where the instrument cluster message
indicates the transmission may not re-engage after
engine shutdown, perform this procedure only in a
desired location (preferably, at an authorized
dealer).

1. Stop the vehicle.

2. Shift the transmission into PARK, if possible.
If not, shift the transmission to NEUTRAL.
3. Push and hold the ignition switch until the engine turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the
transmission will return to normal operation.
NOTE:Even if the transmission can be reset, we
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission. If the transmission
cannot be reset, an authorized dealer service is
required.
Electronic Range Select (ERS) Operation —
If Equipped
The ERS shift control allows the driver to limit the
highest available gear when the transmission is in
DRIVE and ERS mode is not active. For example, if
you set the transmission gear limit to FOURTH
gear, the transmission will hold that gear and not
shift above FOURTH gear, but will shift through the
lower gears normally.
NOTE:ERS will only upshift during a FIRST to SECOND
gear shift when in 4WD LOW. All other ranges will
hold the gear.
You can switch between DRIVE and ERS mode at
any vehicle speed. When the transmission gear
selector is in DRIVE, the transmission will operate
automatically, shifting between all available gears.
Tapping the “-” button (on the steering wheel) will
activate ERS mode, display the current gear in the
instrument cluster, and set that gear as the top
available gear. Once in ERS mode, tapping the “-”
or “+” button will change the top available gear.

STARTING AND OPERATING161
This electronically shifted transfer case provides
four positions:
Two-Wheel Drive High Range (2WD) — This
range is for normal street and highway driving
on dry hard surfaced roads. Driving the vehicle
in 2WD will have greater fuel economy benefits
as the front axle is not engaged in 2WD.
Four-Wheel Drive High Range (4WD HIGH) —
This range provides torque to the front drive -
shaft (engages four-wheel drive) which allows
front and rear wheels to spin at the same speed.
This provides additional traction for loose or
slippery road surfaces only.
Four-Wheel Drive Low Range (4WD LOW) — This
range provides low speed four-wheel drive. It
maximizes torque (increased torque over 4WD
HIGH) to the front driveshaft; allowing front and
rear wheels to rotate at the same speed. This
range provides additional traction and
maximum pulling power for loose or slippery
road surfaces only. Do not exceed 25 mph
(40 km/h) in this range.
N (Neutral) — This range disengages both the
front and rear driveshafts from the powertrain.
To be used for flat towing behind another
vehicle Ú page 228.
NOTE:
The 4WD HIGH and 4WD LOW positions are
designed for loose, slippery road surfaces only.
Driving in the 4WD HIGH and 4WD LOW posi -
tions on dry, hard surfaced roads may cause
increased tire wear and damage to the driveline
components.
The transfer case N (Neutral) button is located
in the center of the 4WD Control Switch and is
pushed by using a ballpoint pen or similar
object. The transfer case N (Neutral) position is
to be used for recreational towing only
Ú page 228.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD
HIGH and 4WD LOW) are located in the instrument
cluster and indicate the current and desired
transfer case selection. When you select a
different transfer case position, the indicator lights
will do the following:

1. The current position indicator light will turn off.

2. The selected position indicator light will flash until the transfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and
remain on.
If the transfer case does not shift into the desired
position, one or more of the following events may
occur:

1. The indicator light for the current position will remain on.

2. The newly selected position indicator light will continue to flash.WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the N (Neutral) position without first
fully engaging the parking brake. The transfer
case N (Neutral) position disengages both the
front and rear drive shaft from the powertrain,
and will allow the vehicle to roll, even if the
transmission is in PARK. The parking brake
should always be applied when the driver is
not in the vehicle.
The transmission may not engage PARK if the
vehicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and
verify that the transmission gear position indi -
cator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly
indicated, before exiting the vehicle.

FUEL SAVER TECHNOLOGY 5.7L ENGINES
ONLY — IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The system
is automatic with no driver inputs or additional
driving skills required.
NOTE:This system may take some time to return to full
functionality after a battery disconnect.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function, included with eTorque
equipped vehicles, is developed to save fuel and
reduce emissions. The system will stop the engine
automatically as the vehicle decelerates at low
speeds if the required conditions are met. Releasing the brake pedal or shifting out of DRIVE
will automatically restart the engine.
Vehicles equipped with eTorque contain a
heavy-duty motor generator and an additional
hybrid electric battery to store energy from vehicle
deceleration used to expand engine off energy
storage and for engine startup after a stop, as well
as providing engine torque assist when conditions
are met to enable this.
AUTOSTOP MODE
The Stop/Start feature is enabled after every
normal customer engine start. It will remain in
STOP/START NOT READY until you drive forward
with a vehicle speed greater than 2 mph (3 km/h).
At that time, the system will go into STOP/START
READY and if all other conditions are met, the
system may go into STOP/START AUTOSTOP
ACTIVE Autostop mode.
To Activate The Autostop Mode, The Following
Must Occur:

1. The system must be in STOP/START READY
state. A STOP/START READY message will be
displayed in the instrument cluster within the
Stop/Start section
Ú
page 114.

2. The vehicle must be decelerating and likely coming to a complete stop.
3. The transmission gear selector must be in DRIVE and the brake pedal pressed. The engine will shut down, the tachometer will
move to the zero position and the stop/start
telltale will illuminate indicating you are in an
Autostop. While in an Autostop, the Climate
Controls system may automatically adjust airflow
to maintain cabin comfort. Customer settings will
be maintained upon return to an engine running
condition.
POSSIBLE REASONS THE ENGINE DOES
N
OT AUTOSTOP
Prior to engine shut down, the system will check
many safety and comfort conditions to see if they
are fulfilled. In following situations, the engine will
not Autostop:
Driver’s seat belt is not buckled
Driver’s door is not closed
The vehicle is on a steep grade
Cabin heating or cooling is in process and an
acceptable cabin temperature has not been
achieved
HVAC is set to full defrost mode at a high blower
