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
(321 kilometers) in some cases.

INSTRUMENT CLUSTER DISPLAY
Your vehicle is equipped with an instrument cluster
display, which offers useful information 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 display located on the instrument
panel, your instrument cluster display can show
you how systems are working and give you
warnings when they are not. The steering wheel
mounted controls allow you to scroll through the
main menus and submenus. You can access the
specific information you want and make selections
and adjustments.

114STARTING AND OPERATING
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 or Number 1 ULSD Fuel
results in a noticeable decrease in fuel
economy.
Climatized ULSD Fuel is a blend of Number 2
ULSD and Number 1 ULSD 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 ULSD Fuel. Use
of incorrect fuel could result in engine and
exhaust system damage Ú page 399.
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 tempera -
ture 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
For the correct engine oil viscosity Ú page 341.
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 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 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 a 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 Volt AC powered battery
blankets will greatly increase starting capability at
low temperatures. Suitable battery blankets are
available from an authorized Mopar® dealer.

REFUELING THE VEHICLE— GASOLINE
ENGINE
NOTE:When the fuel nozzle “clicks” or shuts off the fuel
tank is full.
NOTE:Tighten the gas cap a quarter turn until you hear
one click. This is an indication that the cap is
properly tightened.
If the gas cap is not tightened properly, the
Malfunction Indicator Light will come on. Be sure
the gas cap is tightened every time the vehicle is
refueled.
LOOSE FUEL FILLER CAP MESSAGE
If the vehicle diagnostic system determines that
the fuel filler cap is loose, improperly installed, or damaged, a loose gASCAP indicator will display in
the instrument cluster telltale display area
Ú
page 81. Tighten the fuel filler cap properly and
push the RIGHT button to turn off the message. If
the problem continues, the message will appear
the next time the vehicle is started.
REFUELING THE VEHICLE — DIESEL ENGINE
NOTE:
When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
Tighten the fuel filler cap until you hear a
“clicking” sound. This is an indication that the
fuel filler cap is properly tightened.
Make sure that the fuel filler cap is tightened
each time the vehicle is refueled.
The inlet for the engine air intake is located
behind the passenger side headlamp and
receives air through the grille.
CAUTION!
Damage to the fuel system or emissions
control system could result from using an
improper fuel tank filler tube cap (fuel filler
cap). A poorly fitting cap could let impurities
into the fuel system. Also, a poorly-fitted after
-
market cap can cause the Malfunction Indi -
cator Light (MIL) to illuminate due to fuel
vapors escaping from the system.
A poorly fitting fuel filler cap may cause the
MIL to turn on.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling.
WARNING!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. This is in violation of most state
and federal fire regulations and may cause
the MIL to turn on.
WARNING!
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!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.

DEF FILL PROCEDURE
NOTE:
For the correct fluid type Ú page 404.
Remove cap from DEF tank (located on drivers side
of the vehicle or in fuel door).

DEF Filler Cap And Fuel Fill Chassis Cab Models

NOTE:
The DEF gauge may take up to five seconds to
update after adding a gallon or more of 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 possibly 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.
At 40°F (4°C) you could see some increase in
the DEF gauge due to the tank thawing. The
gauge and level sensor are working properly and
are just updating with proper thawed DEF.
Excessive overfilling of the DEF tank can result
in a MIL lamp/fault code and inaccurate level
readings.
Refilling With Nozzles
You can fill up at any DEF distributor.
Proceed as follows:
Insert the DEF nozzle in the filler tube, start
refilling and stop refilling at the first shut-off (the
shut-off indicates that the DEF tank is full). DO
NOT proceed with the refilling, to prevent
spillage of DEF.
Extract the nozzle. Refilling With Containers
Proceed as follows:
Check the expiration date.
Read the advice for use on the label before
pouring the content of the bottle into the DEF
tank.
After the indication appears on the instrument
cluster display
Úpage 81 fill the DEF tank with
no more than 6 gallons (22 liters).
1 — Diesel Exhaust Fluid (DEF) Fill Location
2 — Diesel Fuel Fill Location
CAUTION!
To avoid DEF spillage, and possible damage to
the DEF tank from overfilling, do not “top off”
the DEF tank after filling.
DO NOT OVERFILL. DEF will freeze below 12ºF
(-11ºC). The DEF system is designed to work in
temperatures below the DEF freezing point,
however, if the tank is overfilled and freezes,
the system could be damaged.
When DEF is spilled, clean the area immedi -
ately with water and use an absorbent mate -
rial to soak up the spills on the ground.
Do not attempt to start your engine if DEF is
accidentally added to the diesel fuel tank as it
can result in severe damage to your engine,
including but not limited to failure of the fuel
pump and injectors.
