3. Fully insert the fuel nozzle into the filler pipe.
4. Fill the vehicle with fuel.
NOTE:
When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
 Wait five seconds before removing the fuel nozzle
to allow excess fuel to drain from the nozzle.
5. Remove the fuel nozzle, reinstall fuel cap and close fuel filler door.
NOTE:Tighten the fuel filler cap about a quarter turn until you
hear one click. This is an indication that the cap is properly
tightened.
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 see
Úpage 321.
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 see
Úpage 323.
DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective Catalytic
Reduction (SCR) 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. A
small quantity of Diesel Exhaust Fluid (DEF) is injected into
the exhaust upstream of a catalyst 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.

2 — DEF Filler
CAUTION!
For diesel engines, only use diesel fuel for motor
vehicles in accordance with ASTM D-975 Grade S15
specifications. The use of other products or mixtures
may damage the engine beyond repair and
consequently void the warranty, due to the damage
caused. If you accidentally introduce other types of fuel
into the tank, do not start the engine. Empty the tank. If
the engine has been run for even an extremely limited
amount of time, you must not only drain the fuel tank,
but the rest of the supply circuit as well.
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.

TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.

Weight Distribution

Consider the following items when computing the weight
on the rear axle of the vehicle:
The tongue weight of the trailer.
 The weight of any other type of cargo or equipment put
in or on your vehicle.
 The weight of the driver and all passengers.
NOTE:Remember that everything put into or on the trailer adds
to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options must
be considered as part of the total load on your vehicle.
Refer to the Tire And Loading Information Placard for the
maximum combined weight of occupants and cargo for
your vehicle.
TOWING REQUIREMENTS
To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended:
WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:
Make certain that the load is secured in the trailer
and that it will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.
 When hauling cargo, or towing a trailer, do not over -
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance, or damage to
brakes, axle, engine, transmission, steering, suspen -
sion, chassis structure, or tires.
 Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross
the chains under the trailer tongue and allow enough
slack for turning corners.
Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in
PARK. Always block or "chock" the trailer wheels.
 GCWR must not be exceeded.
 Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
 GVWR
 GTW
 GAWR
 Tongue weight rating for the trailer hitch utilized
CAUTION!
Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
 Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps the
engine and other parts of the vehicle wear in at the
heavier loads.
WARNING!

STARTING AND OPERATING181
GETTING HIGH-CENTERED
If you get hung up or high-centered on an object, get out of
the vehicle and try to determine what the vehicle is hung
up on, where it is contacting the underbody and what is
the best direction to recover the vehicle. Depending on
what you are in contact with, jack the vehicle up and place
a few rocks under the tires so the weight is off of the high
point when you let the vehicle down. You can also try
rocking the vehicle or winching the vehicle off the object.
Hill Climbing
Hill climbing requires good judgment and a good
understanding of your abilities and your vehicle's
limitations. Hills can cause serious problems. Some are
just too steep to climb and should not be attempted. You
should always feel confident with the vehicle and your
abilities. You should always climb hills straight up and
down. Never attempt to climb a hill on an angle.
BEFORE CLIMBING A STEEP HILL
As you approach a hill, consider its grade or steepness.
Determine if it is too steep. Look to see what the traction
is on the hill side trail. Is the trail straight up and down?
What is on top and the other side? Are there ruts, rocks,
branches or other obstacles on the path? Can you safely
recover the vehicle if something goes wrong? If everything
looks good and you feel confident, shift the transmission
into a lower gear with 4L engaged, and proceed with
caution, maintaining your momentum as you climb the hill.
DRIVING UP HILL
Once you have determined your ability to proceed and
have shifted into the appropriate gear, line your vehicle up
for the straightest possible run. Accelerate with an easy
constant throttle and apply more power as you start up the
hill. Do not race forward into a steep grade; the abrupt
change of grade could cause you to lose control. If the
front end begins to bounce, ease off the throttle slightly to
bring all four tires back on the ground. As you approach
the crest of the hill, ease off the throttle and slowly
proceed over the top. If the wheels start to slip as you
approach the crest of a hill, ease off the accelerator and
maintain headway by turning the steering wheel no more
than a 1/4 turn quickly back and forth. This will provide a
fresh "bite" into the surface and will usually provide
enough traction to complete the climb. If you do not make
it to the top, place the vehicle in REVERSE and back
straight down the grade using engine resistance along
with the vehicle brakes.
DRIVING DOWNHILL
Before driving down a steep hill, you need to determine if
it is too steep for a safe descent. What is the surface
traction? Is the grade too steep to maintain a slow,
controlled descent? Are there obstacles? Is it a straight
descent? Is there plenty of distance at the base of the hill
to regain control if the vehicle descends to fast? If you feel
confident in your ability to proceed, then make sure you
are in 4L and proceed with caution. Allow engine braking
to control the descent and apply your brakes, if necessary,
but do not allow the tires to lock.
CAUTION!
Do not attempt to cross a log with a greater diameter
than the running ground clearance or the vehicle will
become high-centered.
CAUTION!
Winching or rocking the vehicle off hard objects
increases the risk of underbody damage.
WARNING!
Never attempt to climb a hill at an angle or turn around
on a steep grade. Driving across an incline increases
the risk of a rollover, which may result in severe injury.
WARNING!
Do not descend a steep grade in NEUTRAL. Use vehicle
brakes in conjunction with engine braking. Descending
a grade too fast could cause you to lose control and be
seriously injured or killed.

182STARTING AND OPERATING
DRIVING ACROSS AN INCLINE
If at all possible, avoid driving across an incline. If it is
necessary, know your vehicle's abilities. Driving across an
incline places more weight on the downhill wheels, which
increases the possibilities of a downhill slide or rollover.
Make sure the surface has good traction with firm and
stable soils. If possible, transverse the incline at an angle
heading slightly up or down.
IF YOU STALL OR BEGIN TO LOSE HEADWAY
If you stall or begin to lose headway while climbing a steep
hill, allow your vehicle to come to a stop and immediately
apply the brake. Restart the engine and shift into
REVERSE. Back slowly down the hill allowing engine
braking to control the descent and apply your brakes, if
necessary, but do not allow the tires to lock.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided, if possible, and only
be attempted when necessary in a safe, responsible
manner. Only drive through areas which are designated
and approved. Tread lightly and avoid damage to the
environment. Know your vehicle's abilities and be able to
recover it if something goes wrong. Never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls, do not
attempt to restart it. Determine if it has ingested water
first. The key to any crossing is low and slow. Shift into
FIRST gear (manual transmission), or DRIVE (automatic
transmission), with the transfer case in the 4L position
and proceed very slowly with a constant slow speed of {3
to 5 mph (5 to 8 km/h) maximum} and light throttle. Keep
the vehicle moving; do not try to accelerate through the
crossing. After crossing any water higher than the bottom
of the axle differentials, inspect all of the vehicle fluids for
signs of water ingestion.
BEFORE YOU CROSS ANY TYPE OF WATER
As you approach any type of water, you need to determine
if you can cross it safely and responsibly. If necessary, get
out and walk through the water or probe it with a stick. You
need to be sure of its depth, approach angle, current and
bottom condition. Be careful of murky or muddy waters;
check for hidden obstacles. Make sure you will not be
intruding on any wildlife, and you can recover the vehicle
if necessary. The key to a safe crossing is the water depth,
current and bottom conditions. On soft bottoms, the
vehicle will sink in, effectively increasing the water level on
the vehicle. Be sure to consider this when determining the
depth and the ability to safely cross.
CROSSING PUDDLES, POOLS, FLOODED
AREAS OR OTHER STANDING WATER
Puddles, pools, flooded or other standing water areas
normally contain murky or muddy waters. These water
types normally contain hidden obstacles and make it
difficult to determine an accurate water depth, approach
angle, and bottom condition. Murky or muddy water holes
are where you want to hook up tow straps prior to entering.
This makes for a faster, cleaner and easier vehicle
recovery. If you are able to determine you can safely cross,
than proceed using the low and slow method.
WARNING!
Driving across an incline increases the risk of a rollover,
which may result in severe injury.
WARNING!
If the engine stalls or you lose headway or cannot make
it to the top of a steep hill or grade, never attempt to
turn around. To do so may result in tipping and rolling
the vehicle, which may result in severe injury. Always
back carefully straight down a hill in REVERSE. Never
back down a hill in NEUTRAL using only the vehicle
brakes. Never drive diagonally across a hill, always drive
straight up or down.
CAUTION!
Water ingestion into the axles, transmission, transfer
case, engine or vehicle interior can occur if you drive
too fast or through too deep of water. Water can
cause permanent damage to engine, driveline or
other vehicle components, and your brakes will be
less effective once wet and/or muddy.
 When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering
as a precaution, and check all fluids afterward.
Driving through water may cause damage that may
not be covered by the New Vehicle Limited Warranty.
CAUTION!
Muddy waters can reduce the cooling system
effectiveness by depositing debris onto the radiator.
