per minute (RPM x 1000).
2. Voltmeter
When the vehicle is in the RUN state, the gauge indicates the electrical system
voltage. The pointer should stay within
the normal range if the battery is
charged. If the pointer moves to either
extreme left or right and remains there
during normal driving, the electrical
system should be serviced.
3. Instrument Cluster Display
When the appropriate conditions exist, this display shows the instrument cluster
display messages. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further informa -
tion. 4. Oil Pressure Gauge
The pointer should always indicate the oil
pressure when the engine is running. A
continuous high or low reading under
normal driving conditions may indicate a
lubrication system malfunction. Imme -
diate service should be obtained from an
authorized dealer.
5. Speedometer
Indicates vehicle speed.
6. 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.
Refer to “Refueling The Vehicle — Gas
Engine” in “Starting And Operating” for
further information. 7. Temperature Gauge
The gauge pointer shows engine coolant
temperature. The pointer positioned
within the normal range indicates that
the engine cooling system is operating
satisfactorily.
The gauge pointer will likely indicate a higher temperature when driving in hot
weather, up mountain grades, or when
towing a trailer. 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. If you decide to look under the

5. Diesel Exhaust Fluid (DEF) Gauge
The DEF Gauge displays the actual level of Diesel Exhaust Fluid in the DEF tank.
Diesel Exhaust Fluid (DEF) is required to
maintain normal vehicle operation and
emissions compliance. If something is
wrong with the gauge, a DEF Warning
Message or Malfunction Indicator Light
(MIL) will be displayed. More information
is available in the instrument cluster
display section under the heading of
Diesel Exhaust Fluid (DEF) Warning
Messages.
NOTE:
The DEF tank on these vehicles is designed
with a large amount of full reserve. So the
level sensor will indicate a full reading even
before the tank is completely full. To put it
another way, there’s additional storage
capacity in the tank above the Full mark
that’s not represented in the gauge. You may
not see any movement in the reading – even after driving up to 200 miles (322 kilome
-
ters) in some cases.
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 an authorized dealer for service.
The DEF gauge may also not immediately
update after a refill if the temperature of the
DEF fluid is below 39°F (4°C). The DEF tank
heater will 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.
INSTRUMENT CLUSTER DISPLAY
Your vehicle will be equipped with an instru -
ment cluster display, which offers useful infor -
mation to the driver. With the ignition in the OFF
mode, opening/closing of a door will activate
the display for viewing, and display the total
miles, or kilometers, in the odometer. Your
instrument cluster display is designed to display
important information about your vehicle’s
systems and features. Using a driver interactive

NOTE:
After an accident, remember to cycle the ignition
to the STOP (OFF/LOCK) position and remove the
key from the ignition switch to avoid draining the
battery. Carefully check the vehicle for fuel leaks
in the engine compartment and on the ground
near the engine compartment and fuel tank
before resetting the system and starting the
engine. If there are no fuel leaks or damage to the
vehicle electrical devices (e.g. headlights) after an
accident, reset the system by following the proce -
dure described below. If you have any doubt,
contact an authorized dealer.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident
Response System functions after an event, the
ignition switch must be changed from ignition
START or ON/RUN to ignition OFF. Carefully
check the vehicle for fuel leaks in the engine
compartment and on the ground near the
engine compartment and fuel tank before reset -
ting the system and starting the engine.
Maintaining Your Air Bag System
WARNING!
Modifications to any part of the air bag
system could cause it to fail when you need
it. You could be injured if the air bag system
is not there to protect you. Do not modify
the components or wiring, including adding
any kind of badges or stickers to the
steering wheel hub trim cover or the upper
passenger side of the instrument panel. Do

STARTING AND OPERATING223
NOTE:
Use of Climatized Ultra Low Sulfur Diesel Fuel
or Number 1 Ultra Low Sulfur Diesel Fuel
results in a noticeable decrease in fuel
economy.
Climatized Ultra Low Sulfur Diesel Fuel is a
blend of Number 2 Ultra Low Sulfur and
Number 1 Ultra Low Sulfur Diesel Fuels
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. Refer to “Fuel Requirements” in
“Technical Specifications” for further infor -
mation.
If climatized or diesel Number 1 ULSD fuel is
not available, and you are operating below
(20°F/-6°C), in sustained arctic conditions,
Mopar Premium Diesel Fuel Treatment (or
equivalent) is recommended to avoid gelling
(see Fuel Operating Range Chart).
Under some circumstances increased
engine noise may be audible in the seconds
following a cold start. This is most likely to
occur when using fuel that isn't blended for
the ambient temperature present. This may
occur on an unseasonably cold day or when
a truck is fueled in a warmer climate and
driven to a colder climate. The noise can
typically be prevented by using Mopar
Premium Diesel Fuel Treatment as recom-
mended (see Fuel Operating Range Chart).
Engine Oil Usage
Refer to “Dealer Service” in “Servicing And
Maintenance” for the correct engine oil
viscosity.
Winter Front Cover Usage
A Winter front or cold weather cover is to be
used in ambient temperatures below 32°F
(0°C), especially during extended idle condi -
tions. 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 left in the
full open position to allow air flow to the charge
air cooler 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
your Mopar dealer.
Battery Blanket Usage
A battery loses 60% of its cranking power as the
battery temperature decreases to 0°F (-18°C).
For the same decrease in temperature, the
engine requires twice as much power to crank
at the same RPM. The use of 120 VAC powered
battery blankets will greatly increase starting
capability at low temperatures. Suitable battery
blankets are available from your authorized
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.
NOTE:
High-speed, no-load running of a cold engine
can result in excessive white smoke and poor
engine performance. No-load engine speeds
should be kept under 1,000 RPM during the
warm-up period, especially in cold ambient
temperature conditions.

STARTING AND OPERATING225
1. With the transmission in PARK, the parking
brake applied, and the engine running,
push the speed control switch to the ON
position, then push the SET switch.
2. The engine RPM will go up to 1,100 RPM. To increase the RPM, push and hold the
ACCEL/RESUME switch and the idle speed
will increase to approximately 1,500 RPM.
To decrease the RPM, push and hold the
DECEL switch and the idle speed will
decrease to approximately 1,100 RPM.
3. To cancel the Idle–Up feature, either push the CANCEL switch, push the ON/OFF
switch, or press the brake pedal.
Noise
Diesel engines can create noises that may
seem concerning. The nature of a diesel engine
is compression ignition where compressed air and fuel are mixed and ignited. Weather, baro
-
metric pressure, altitude, and temperature will
affect how fuel is ignited in the engine. Engines
will sound different from day to day or previous
model years. Clicking, ticking, or light knocking
is normal and will change from day to day, as
the engine breaks in, and can vary with changes
in ambient temperature. Clicking sound from
under the hood shortly after vehicle shutdown is
normal as actuators such as the EGR valve are
cycled. Fuel pump noise may increase during
low speed/light load conditions when ambient
temperature is above 100°F (38°C), and when
fuel tank level is below 10% which is a normal
condition of the fuel system and controls
strategy. Diesel equipped vehicles also have an
exhaust after-treatment system to reduce emis -
sions utilizing a DPF (refer to “Odor” in this
section for further information) and a Selective
Reduction Catalyst (SCR). The SCR reduces
Nitrogen Oxides (NOx) using the Diesel Exhaust Fluid (DEF) system. DEF is injected directly into
the SCR through a dosing module. This process
will create a clicking sound and at times, will
make noise even with the vehicle shut off. This
is normal as the DEF dosing module is purging
DEF. If at any time the check engine light is on,
please visit an authorized dealer.
Stopping The Engine
Idle the engine a few minutes before routine
shutdown. After full load operation, idle the
engine three to five minutes before shutting it
down. This idle period will allow the lubricating
oil and coolant to carry excess heat away from
the combustion chamber, bearings, internal
components, and turbocharger. This is espe
-
cially important for turbocharged, charge
air-cooled engines. Refer to the following chart
for proper engine shutdown:

ENGINE RUNAWAY — DIESEL ENGINE
Diesel engine runaway is a rare condition
affecting diesel engines, where the engine
consumes its own lubrication oil and runs at
higher and higher RPM until it overspeeds to a
point where it destroys itself due to either
mechanical failure or engine seizure through
lack of lubrication.
REFUELING THE VEHICLE — GAS ENGINE
The fuel filler cap (gas cap) is located behind the
fuel filler door, on the left side of the vehicle.
Open the fuel door and remove the fuel filler cap
by turning it counter-clockwise.
Fuel Filler Cap
NOTE:
When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler door.
WARNING!
In case of engine runaway due to flammable
fumes from fuel spills or turbocharger oil
leaks being sucked into the engine, do the
following to help avoid personal injury and/or
vehicle damage:
1. Turn the ignition switch to the OFF position.
2. Using a CO2 or dry chemical type fire
extinguisher, direct the spray from the fire
extinguisher into the grille on the driver side
so that the spray enters the engine air intake.
The inlet for the engine air intake is located
behind the drivers side headlamp and
receives air through the grille.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the gas cap is
removed or the tank is being filled.
Never add fuel to the vehicle when the
engine is running.
A fire may result if gasoline is pumped into
a portable container that is inside of a
vehicle. You could be burned. Always place
gas containers on the ground while filling.
CAUTION!
Damage to the fuel system or emissions
control system could result from using an
improper fuel tank filler tube cap.
A poorly fitting fuel filler cap could let impu -
rities into the fuel system.
A poorly fitting fuel filler cap may cause the
“Malfunction Indicator Light (MIL)” to turn
on.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling. When the
fuel nozzle “clicks” or shuts off, the fuel
tank is full.
