3. Insert the fuel nozzle fully into the filler pipe – the nozzle opens and holds the flapper door
while refueling.
4. Fill the vehicle with fuel – when the fuel nozzle “clicks” or shuts off, the fuel tank is full.
5. Remove the fuel nozzle and close the fuel door.
AVOID USING CONTAMINATED FUEL
Fuel that is contaminated by water or dirt can
cause severe damage to the engine fuel system.
Proper maintenance of the engine fuel filter and
fuel tank is essential Ú page 408.
WARNING!
Always place container on the ground before
filling.
Keep the pump nozzle in contact with the
container when you are filling it.
Use only approved containers for flammable
liquid.
Do not leave container unattended while
filling.
A static electric charge could cause a spark
and fire hazard.

2 — Diesel Fuel Fill Location
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light (MIL) to turn on.
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!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.

STARTING AND OPERATING209
BULK FUEL STORAGE — DIESEL FUEL
If you store quantities of fuel, good maintenance of
the stored fuel is also essential. Fuel contaminated
with water will promote the growth of “microbes.”
These microbes form “slime” that will clog the fuel
filtration system and lines. Drain condensation
from the supply tank and change the line filter on
a regular basis.
NOTE:When a diesel engine is allowed to run out of fuel,
air is pulled into the fuel system.
If the vehicle will not start Úpage 414.
DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective Catalytic
Reduction (SCR) system to meet diesel emissions
standards required by the Environmental
Protection Agency. The purpose of the SCR system is to reduce levels
of oxides of nitrogen (NO
x) emitted from engines
that are harmful to our health and the environment
to a near-zero level. A small quantity of Diesel
Exhaust Fluid (DEF) is injected into the exhaust
upstream of a catalyst where, when vaporized,
converts smog-forming NO
x into harmless
nitrogen (N
2) and water vapor (H2O), two natural
components of the air we breathe.
DIESEL EXHAUST FLUID STORAGE
Diesel Exhaust Fluid (DEF) is considered a very
stable product with a long shelf life. If DEF is kept
in temperatures between 10° and 90°F (-12° and
32°C), it will last a minimum of one year.
DEF may freeze at temperatures at or below 12°F
(-11°C). The system has been designed to operate
in this environment.
NOTE:When working with DEF, it is important to know
that:
Any containers or parts that come into contact
with DEF must be DEF compatible (plastic or
stainless steel). Copper, brass, aluminum, iron
or non-stainless steel should be avoided as they
are subject to corrosion by DEF.
If DEF is spilled, it should be wiped up
completely.
ADDING DIESEL EXHAUST FLUID
The Diesel Exhaust Fluid (DEF) gauge (located on
the instrument cluster) will display the level of DEF
remaining in the tank Ú page 110.
NOTE:
Driving conditions (altitude, vehicle speed, load,
etc.) will effect the amount of DEF that is used in
your vehicle.
Outside temperature can affect DEF consump -
tion. In cold conditions, 12°F (-11°C) and
below, the DEF gauge may take longer to
operate as intended. This is a normal function of
the system.
There is an electric heater inside the DEF tank
that automatically works when necessary. If the
DEF supply does freeze, the truck will operate
normally until it thaws.WARNING!
Do not open the high pressure fuel system with
the engine running. Engine operation causes
high fuel pressure. High pressure fuel spray can
cause serious injury or death.

352SAFETY
If you do have a collision which deploys the air
bags, any or all of the following may occur:
The air bag material may sometimes cause
abrasions and/or skin reddening to the occu -
pants as the air bags deploy and unfold. The
abrasions are similar to friction rope burns or
those you might get sliding along a carpet or
gymnasium floor. They are not caused by
contact with chemicals. They are not permanent
and normally heal quickly. However, if you
haven’t healed significantly within a few days, or
if you have any blistering, see your doctor imme -
diately.
As the air bags deflate, you may see some
smoke-like particles. The particles are a normal
by-product of the process that generates the
non-toxic gas used for air bag inflation. These
airborne particles may irritate the skin, eyes,
nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation
continues, see your doctor. If these particles
settle on your clothing, follow the garment
manufacturer’s instructions for cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another collision,
the air bags will not be in place to protect you.
NOTE:
Air bag covers may not be obvious in the interior
trim, but they will open during air bag deploy -
ment.
After any collision, the vehicle should be taken
to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication
network remains intact, and the power remains
intact, depending on the nature of the event, the
Occupant Restraint Controller (ORC) will determine
whether to have the Enhanced Accident Response
System perform the following functions:
Cut off fuel to the engine (if equipped)
Cut off battery power to the electric motor (if
equipped)
Flash hazard lights as long as the battery has
power
Turn on the interior lights, which remain on as
long as the battery has power or for 15 minutes
from the intervention of the Enhanced Accident
Response System
Unlock the power door locks
Your vehicle may also be designed to perform any
of these other functions in response to the
Enhanced Accident Response System:
Turn off the Fuel Filter Heater, Turn off the HVAC
Blower Motor, Close the HVAC Circulation Door
Cut off battery power to the:
Engine
Electric Motor (if equipped)
Electric power steering
Brake booster
Electric park brake
Automatic transmission gear selector
Horn
Front wiper
Headlamp washer pump (if equipped)
WARNING!
Deployed air bags and seat belt pretensioners
cannot protect you in another collision. Have the
air bags, seat belt pretensioners, and the seat
belt retractor assemblies replaced by an
authorized dealer immediately. Also, have the
Occupant Restraint Controller System serviced
as well.
