Temperature Knob:Turn the middle knob located
clockwise or counterclockwise to increase or decrease
the temperature inside of your vehicle. Turn the
knob toward the red area for warmer air. Turn the knob
toward the blue area for cooler air.
Turn the mode knob on the far right clockwise or
counterclockwise to direct the airflow inside of your
vehicle.
To change the current mode, select one of the following:
9(Off):This setting turns the system off.
H(Vent):This mode directs air to the instrument
panel vents.
)(Bi-Level):This mode directs half of the air to the
instrument panel vents, then directs the remaining
air to the floor vents. Cooler air is directed to the upper
vents and warmer air to the floor vents.
6(Floor):This mode directs most of the air to the floor
vents. Use this mode to send air to the rear of the vehicle.
Keep the area under the front seats free of objects that
could obstruct airflow to the rear of the vehicle.
The mode knob can also be used to select the defrost
mode. For more information, see “Defogging and
Defrosting” later in this section.If your vehicle has air conditioning, the controls will look
like this:
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
<(Maximum Air Conditioning):Turn the right knob
to this setting for maximum cooling. This setting
puts the system in recirculation mode and helps to
maximize your air conditioner’s performance and your
vehicle’s fuel economy. This setting also cools the
air the fastest.
Y(Air Conditioning):This setting is used for normal
cooling on hot days. It cools outside air and directs
it through the instrument panel vents.Vehicles With Air Conditioning

If your vehicle has tow hooks, the hooks are at the front
and, on some models, the rear of the vehicle. You
may need to use them if you are stuck off-road and need
to be pulled to some place where you can continue
driving.Loading Your Vehicle
It is the responsibility of the Final Stage manufacturer to
install a Certification label on your vehicle. This label
shows how much weight your vehicle can properly carry.
It may also show the size of the vehicle’s original
tires, and the inflation pressures needed to obtain the
gross weight capacity of your vehicle. This is called the
Gross Vehicle Weight Rating (GVWR). The tire
information could also be shown on a separate Tire
Information label.
The GVWR includes the weight of the vehicle, all
occupants, fuel, and cargo.
The Certification label also tells you the maximum
weight for the front and rear axles, called the Gross Axle
Weight Rating (GAWR). To find out the actual loads
on your front and rear axles, go to a weigh station and
weigh your vehicle. Your dealer can help you with
this. Be sure to spread out your load equally on both
sides of the center line.

Water In Fuel Light
Problem Recommended Action
Light comes on
intermittently.Drain water from the fuel
filter.
Light stays on at
temperatures above
freezing.Drain the fuel filter
immediately. If no water
can be drained and the
light stays on, see your
dealer/retailer for
assistance.
Light stays on at
temperatures below
freezing.Drain the fuel filter
immediately. If no water
can be drained, water
may be frozen in the
water drain system, or in
the fuel lines. Move the
vehicle to a warm location
to thaw out, and then
drain the filter system.
Light stays on
immediately after
refueling, and a large
amount of water was
possibly pumped into the
fuel tank.Fuel tank purging is
required. See your
dealer/retailer for
assistance.Notice:If you drive when this warning indicator is
on, you can damage your fuel injection system
and your engine. If the indicator comes on right after
you refuel, it means water was pumped into your
fuel tank. Turn off your engine immediately.
Then, have the water drained at once.
To drain water, do the following:
1. Stop and park the vehicle in a safe place. Turn off
the engine and apply the parking brake.
2. Remove the fuel cap.
3. Place a fuel-resistant container under the fuel filter.
The filter drain valve is located on the bottom of the
fuel filter.
If your vehicle has the 6.6L engine, the fuel filter is
located in the engine compartment on the driver’s
side of the vehicle. If your vehicle has either the
7.2L or 7.8L engine, the fuel filters are located in the
engine compartment on the driver’s side of the
vehicle, and on the driver’s side frame rail in front of
the fuel tank.
5-13

4. Open the drain valve
by turning two to three
turns. When fuel
empties from the valve,
all the water has been
drained. Close the
valve hand-tight.
5. Remove the fuel-resistant container and properly
dispose of the contaminated fuel. To find out how
to properly dispose of contaminated diesel fuel, see
Engine Oil (Caterpillar
®Diesel Engine) on
page 5-23orEngine Oil (Gasoline Engine) on
page 5-24orEngine Oil (DURAMAX
®Diesel Engine)
on page 5-28orEngine Oil (Isuzu Diesel Engine) on
page 5-32.
6. Install the fuel cap.
7. Start the engine and let it run for a few minutes.
If the engine stalls, the fuel system may need to
be primed. While draining the water from the fuel
filter, air may enter the fuel system. If air has entered
the fuel system the fuel system will need to be
primed.If the water-in-fuel light comes on again after driving a
short distance or the engine runs rough or stalls, a large
amount of water has probably been pumped into the
fuel tank. The fuel tank should be purged.
Fuel Priming
If your vehicle has a Caterpillar®diesel engine, see the
Caterpillar®Diesel Engine Operation and Maintenance
Manual provided with your vehicle.
If your vehicle has a DURAMAX
®diesel engine, in
order for the fuel system to work properly, the fuel lines
must be full of fuel and contain no air. If air gets into the
fuel lines, it will be necessary to prime the fuel lines to
eliminate air before operating the vehicle.
Air can get into the fuel lines if any of the following
happen:
•The vehicle runs out of fuel.
•The fuel filter is removed for servicing or
replacement.
•The fuel lines are removed or disconnected for
servicing.
•The fuel filter water drain valve is opened while the
engine is running.
5-14

Filling the Tank
{CAUTION:
Fuel vapor is highly ammable. It burns
violently, and that can cause very bad injuries.
Do not smoke if you are near fuel or refueling
your vehicle. Keep sparks, ames and smoking
materials away from fuel.The fuel cap can be on either or both sides of your
vehicle depending on option content.
To take off the cap, turn it slowly counterclockwise.
{CAUTION:
If you get fuel on yourself and then something
ignites it, you could be badly burned. Fuel can
spray out on you if you open the fuel cap too
quickly. This spray can happen if your tank is
nearly full, and is more likely in hot weather.
Open the fuel cap slowly and wait for any
“hiss” noise to stop. Then unscrew the cap all
the way.
When you put the cap back on, turn it clockwise until it
is tight.
Notice:If you need a new fuel cap, be sure to get
the right type. Your dealer/retailer can get one for
you. If you get the wrong type, it may not t properly.
This may cause your malfunction indicator lamp to
light and may damage your fuel tank and emissions
system. SeeMalfunction Indicator Lamp on
page 3-36. Fuel caps for all
gasoline applications,
and all diesel between
frame rail fuel tank
applications
Fuel caps for all side
mounted diesel
applications
5-20

If you have dual tanks, fill the driver’s side tank, or
forward tank, first. The fuel gage will give better readings
this way. Your gage will show the total fuel left in both
tanks.
If your vehicle is a C4/C5 model and you have dual
tanks, the engine must be off when refueling or the fuel
transfer system may become inoperable.
If you have a single tank with dual fillers, where there is
a filler on each side of the vehicle, do not attempt to
fill the tank through both fillers at the same time. Also,
do not fill the tank with both caps removed, as this
may result in over-filling the tank and fuel spillage.Filling a Portable Fuel Container
{CAUTION:
Never ll a portable fuel container while it is in
your vehicle. Static electricity discharge from
the container can ignite the fuel vapor. You
can be badly burned and your vehicle
damaged if this occurs. To help avoid injury to
you and others:
Dispense fuel only into approved
containers.
Do not ll a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed, or
on any surface other than the ground.
Bring the ll nozzle in contact with the
inside of the ll opening before operating
the nozzle. Contact should be maintained
until the lling is complete.
Do not smoke while pumping fuel.
Do not use a cellular phone while
pumping fuel.
5-21

4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the engine
cooling fan.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower, add
more of the proper mixture to the coolant surge tank
until the level reaches slightly above the FULL
COLD mark.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
Engine Fan Noise
Your vehicle has a clutched engine cooling fan. When
the clutch is engaged, the fan spins faster to provide
more air to cool the engine. In most everyday driving
conditions, the clutch is not fully engaged. This improves
fuel economy and reduces fan noise. Under heavy
vehicle loading, trailer towing and/or high outside
temperatures, the fan speed increases when the clutch
engages. So you may hear an increase in fan noise. This
is normal and should not be mistaken as the transmission
slipping or making extra shifts. It is merely the cooling
system functioning properly. The fan will slow down when
additional cooling is not required and the clutch
disengages.
You may also hear this fan noise when you start the
engine. It will go away as the fan clutch disengages.
Power Steering Fluid
SeeScheduled Maintenance on page 6-5to determine
when to check your power steering fluid.
5-54

Notice:Do not let anyone tell you that
under-ination or over-ination is all right. It is
not. If your tires do not have enough air
(under-ination), you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-ination),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazards
When to Check
Check your tires once a month or more.
Also, check the tire pressure of the spare tire if your
vehicle has one.
How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your vehicle’s tires are
properly inflated simply by looking at them. Radial tires
may look properly inflated even when they are
underinflated. Check the tire’s inflation pressure when the
tires are cold. Cold means your vehicle has been sitting
for at least three hours or driven no more than
1 mile (1.6 km).
Remove the valve cap from the tire valve stem. Press
the tire gage firmly onto the valve to get a pressure
measurement. If the cold tire inflation pressure matches
the recommended pressure on the Certification or Tire
Information label, no further adjustment is necessary.
If the inflation pressure is low, add air until you reach the
recommended amount. If you overfill the tire, release air
by pushing on the metal stem in the center of the tire
valve. Re-check the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and
moisture.
Wheel Loading
Wheels are stamped with a maximum load and cold
inflation rating. Be sure you do not exceed these limits.
