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.
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,

CAUTION!
To avoid fuel spillage and overfilling, do
not “top off” the fuel tank after filling.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 tight- ened each time the vehicle is refueled.
WARNING!
A fire may result if fuel is pumped into a
portable container that is on a truck bed.
You could be burned. Always place fuel
containers on the ground while filling.
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

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.
