filter/water separator and fuel filter re-
placement.
Normal Starting Procedure
The gear selector must be in the NEUTRAL
(N) position, and the brake pedal must be
pressed, to allow engine cranking. Place the
gear selector in NEUTRAL (N) and apply the
brake pedal BEFORE turning the key to the
START/AVV position; otherwise, the engine
will not crank and the key must be cycled
OFF, then back on, before cranking is al-
lowed.
Observe the instrument panel cluster lights
when starting the engine.NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or press-
ing the accelerator pedal.
1. Press and hold the brake pedal.
2. Place the gear selector into the NEUTRAL
(N) position while keeping the brake pedal
depressed.
3. Turn the ignition switch to the ON/RUN/ MAR position and watch the instrument
panel cluster lights.CAUTION!
If the “Generic Warning Light” remains on
and a “Service Fuel Filter” message dis-
plays, DO NOT START engine before you
drain the water from the fuel filter housing
to avoid engine damage. Please see your
authorized dealer for draining the fuel
filter/water separator and fuel filter re-
placement.
4. After the Glow Plug light turns off, turn the ignition switch to the AVV (START)
position to start the engine. Do not press
the accelerator during starting. 5. If you wish to stop the cranking of the
engine prior to the engine starting, release
the ignition key so that it turns back to the
ON/RUN position.
6. Check that the oil pressure warning light has turned off.
7. Release the parking brake.
To start the engine if the transmission is
faulty, the “Delayed startup” procedure may
be required.
NOTE:
Not all Transmission Failures requires the
“Delayed startup” Procedure, it depends on
the type of failure.(refer to "Instrument Clus-
ter Messages" under "Automated Manual
Transmission" in this section for further infor-
mation):
• Begin with the key in the OFF position.
• Press and hold the brake pedal.
• Turn the key to the START/AVV position and hold it there for at least seven seconds with
the brake depressed. The engine will start,
and the transmission will operate in recov-
ery mode (maximum gear permitted = 3rd,

• A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always
place fuel containers on the ground
while filling.
CAUTION!
• Damage to the fuel system or emissionscontrol system could result from using
an improper fuel tank filler tube cap.
• A poorly fitting fuel filler cap could let
impurities 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. 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.
• If the gas cap is not tightened properly, the MIL may come on. Be sure the gas cap is
tightened every time the vehicle is
refueled.Materials Added To Fuel
Designated TOP TIER
Detergent Gasoline
contains a higher level
of detergents to fur-
ther aide in minimiz-
ing engine and fuel
system deposits. When
available, the usage of
Top Tier Detergent gasoline is recommended.
Visit www.toptiergas.com for a list of TOP
TIER Detergent Gasoline Retailers. Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these
materials intended for gum and varnish re-
moval may contain active solvents or similar
ingredients. These can harm fuel system gas-
ket and diaphragm materials.
REFUELING THE VEHICLE — DIESEL
ENGINE
The fuel cap is located behind the fuel filler
door on the left side of the vehicle. If the fuel
cap is lost or damaged, be sure the replace-
ment cap is for use with this vehicle.
CAUTION!
It is extremely important to avoid any con-
tamination of the Diesel Exhaust Fluid
(DEF) with diesel fuel or other petroleum
products. Ensure that the DEF filler cap is
in place and completely tightened before
opening or filling the diesel fuel tank.

Diesel Exhaust Fluid
Your vehicle is equipped with a Selective
Catalytic Reduction 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. Small
quantities of Diesel Exhaust Fluid (DEF) is injected into the exhaust upstream of a cata-
lyst 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.
System Overview
This vehicle is equipped with a Diesel Ex-
haust Fluid (DEF) injection system and a
Selective Catalytic Reduction (SCR) catalyst
to meet the emission requirements.
The DEF injection system consists of the
following components:
• DEF tank
• DEF pump
• DEF injector
• Electronically-heated DEF lines
• NOx sensors
• Temperature sensors
• SCR catalyst
Fuel/DEF Fill Locations

The DEF injection system and SCR catalyst
enable the achievement of diesel emissions
requirements; while maintaining outstanding
fuel economy, drivability, torque and power
ratings.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
system messages and warnings.
NOTE:
• Your vehicle is equipped with a DEF injec-tion system. You may occasionally hear an
audible clicking noise from under the ve-
hicle at a stop. This is normal operation.
• The DEF pump will run for a period of time after engine shutdown to purge the DEF
system. This is normal operation and may
be audible from under the vehicle.
Adding Diesel Exhaust Fluid
NOTE:
Driving conditions (altitude, vehicle speed,
load, etc.) will effect the amount of DEF that
is used by your vehicle.
DEF Fill Procedure
NOTE:
Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for the correct fluid type.
CAUTION!
It is extremely important to avoid any con-
tamination of the diesel fuel with Diesel
Exhaust Fluid (DEF). Ensure that the die-
sel fuel filler cap is in place and com-
pletely tightened before opening or filling
the DEF.
1. Remove cap from DEF filler neck (located on drivers side of the vehicle in the fuel
door).
2. Insert DEF fill adapter/nozzle into DEF tank filler neck.
CAUTION!
•To avoid DEF spillage, and possible dam-
age to the DEF tank from overfilling, do
not “top off” the DEF tank after filling.
• DO NOT OVERFILL. DEF will freeze be- low 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.

CAUTION!
• When DEF is spilled, clean the areaimmediately with water and use an ab-
sorbent material 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 dam-
age to your engine, including but not
limited to failure of the fuel pump and
injectors.
• Never add anything other than DEF to the tank – especially any form of hydro-
carbon such as diesel fuel, fuel system
additives, gasoline, or any other
petroleum-based product. Even a very
small amount of these, less than
100 parts per million or less than 1 oz.
per 78 gallons (295 liters) will contami-
nate the entire DEF system and will
require replacement. If owners use a
container, funnel or nozzle when refilling
the tank, it should either be new or one
that is has only been used for adding
DEF. Mopar provides an attachable
nozzle with its DEF for this purpose. 3. Stop filling the DEF tank immediately
when any of the following happen:
• DEF stops flowing from the fill bottle into the DEF tank.
• DEF splashes out the filler neck.
• DEF pump nozzle automatically shuts off.
4. Reinstall cap onto DEF filler neck.
Filling The Def Tank In Cold Climates
Since DEF will begin to freeze at 12°F
(-11°C), your vehicle is equipped with an
automatic DEF heating system. This allows
the DEF injection system to operate properly
at temperatures below 12°F (-11°C). If your
vehicle is not in operation for an extended
period of time with temperatures below 12°F
(-11°C), the DEF in the tank may freeze. If
the tank is overfilled and freezes, it could be
damaged. Therefore, do not overfill the DEF
tank.
Extra care should be taken when filling with
portable containers to avoid overfilling.
