Transmission Temperature Gage
If you have an automatic
transmission and this
gage, it is located above
the switchbank in the
center of the instrument
panel.
When your ignition is on, the gage shows the
temperature of the transmission oil. A reading in
the warning zone, the red area beginning at 300°F
(150°C), means you must stop driving and
check into the cause. One possible cause is a low
oil level in the transmission.
Notice:If you drive your vehicle with the
transmission temperature gage above normal
operating range, you can damage the
transmission. This could lead to costly repairs
that would not be covered by your warranty.
Do not drive your vehicle while the
transmission temperature gage reading is
above normal. See your dealer for service.
Exhaust Brake Indicator Light
If your vehicle is
equipped with an
exhaust brake, you will
have this light, located
above the climate
controls in the center of
the instrument panel.
The exhaust brake indicator light will come on and
stay on whenever the diesel engine exhaust brake
or exhaust restrictor is active. For more information,
seeDiesel Engine Exhaust Brake on page 112and
Exhaust Restrictor (Engine Warm-Up) on page 108.
Differential Lock Indicator Light
If your vehicle has this
feature, this light is
located in the center of
the instrument panel.
The light is on when the
rear differential lock
system is in use.

Low Washer Fluid Warning Light
This light is located
above the climate
controls in the center of
the instrument panel.
This light will come on when your vehicle is low on
windshield washer fluid.
For more information, seeWindshield Washer
Fluid on page 296.
Check Gages Warning Light
This light will come on
as you’re starting the
engine, just as a check.
If this light comes on and stays on while you are
driving. It means that either your engine coolant
temperature gage or your engine oil pressure gage
may be showing a reading in the warning zone.
When the check gages light comes on, you
will also hear a warning tone. The tone and the
light will stay activated until the problem is
corrected.
This light may also come on if your vehicle is
equipped with the optional automatic engine
shutdown system and engine shutdown has
begun. SeeEngine Alarm and Automatic

Diesel Engine Fuel
For the Caterpillar®diesel, see the Caterpillar®
Operation & Maintenance Manual for information
concerning fuel usage.
Notice:Diesel fuel or fuel additives not
recommended in this manual could damage
your fuel system and engine. Your warranty
would not cover this damage. And:
Diesel fuel that has been mixed with engine
oil or automatic transmission uid could
damage your engine and emission controls.
Aftermarket diesel fuel additives are not
tested by General Motors. Some additives,
particularly those which contain alcohol or
water emulsiers, may damage your fuel
system. If you believe that unique
circumstances call for a fuel additive to be
used, consult your dealer for advice.
If you ever run out of diesel fuel, it can be
difficult to restart your engine. To avoid this,
never let your tank get empty.
If gasoline is ever accidentally added to the fuel
tank, to avoid severe engine damage, do not run
the engine until the fuel tank can be drained.
If you run out of fuel,Running Out of Fuel on
page 262tells you how to restart your engine.
What Fuel to Use
In the United States, for best results use
No. 2-D diesel fuel year-round (above and below
freezing conditions) as oil companies blend
No. 2-D fuel to address climate differences.
No. 1-D diesel fuel may be used in very cold
temperatures (when it stays below 0°F or−18°C);
however, it will produce a power and fuel
economy loss. Avoid the use of No. 1-D diesel
fuel in warm or hot climates. It may result in
stalling, poor starting when the engine is hot, and
may damage the fuel injection system.
It is important that diesel-powered trucks are
refueled only with ultra low-sulfur fuel. The
emission control system requires the use of diesel
fuel with ultra low-sulfur (0.0015% by weight, or
15 ppm, maximum) content. Both ultra low-sulfur
and higher sulfur diesel fuels are available in
the United States and ultra low-sulfur diesel fuel is
available in Canada. However, only higher
sulfur diesel fuel is available in Mexico. Use of
fuels with higher-sulfur content will affect the
function of the emission components and may
cause reduced performance, excessive smoke,
and unpleasant odor.
253

At a minimum, the diesel fuel you use
should meet the latest version of ASTM
specification D 975 (Grades No. 2-D or No. 1-D
S15 commonly known as Ultra Low Sulfur diesel)
in the United States. In addition, the Engine
Manufacturers Association (EMA) has identified
properties of an improved diesel fuel for better
engine performance and durability. Diesel
fuels corresponding to the EMA Recommended
Guideline on Premium Diesel Fuel (FQP-1A) could
provide better starting, less noise, and better
vehicle performance. If there are questions about
the fuel you are using, contact your fuel supplier.
If your vehicle has the 6.6L engine, it is
acceptable to use diesel fuel containing up to
5% biodiesel (B5), but the final blended fuel must
meet the same specification, ASTM D 975 (Grades
No. 2-D or No. 1-D S15 commonly known as Ultra
Low Sulfur diesel), as other fuels used in your
vehicle, and the biodiesel used for making this
fuel must meet the latest version of ASTM
specification D 6751. Biodiesel is produced from
vegetable oils or animal fat that have been
chemically modified to reduce the possibility of
damage to your fuel system and engine. Higher
concentration (i.e., greater than B5)
biodiesel-containing fuels or the use ofunmodified bio-oils blended into diesel fuel at any
concentration is not recommended and could
damage your fuel system and engine. Such
damage would not be covered by your warranty. If
there are questions about the biodiesel-containing
fuels you are using, contact your fuel supplier.
Diesel fuel may foam when you fill your tank. This
can cause the automatic pump nozzle to shut
off, even though your tank is not full. If this
happens, just wait for the foaming to stop and
then continue to fill your tank. SeeFilling the Tank
on page 264.
{CAUTION:
Heat coming from the engine may cause
the fuel to expand and force the fuel out
of your tank. If something ignites the fuel,
a re could start and people could be
burned. To help avoid this, ll your fuel
tank only until the automatic nozzle shuts
off. Do not try to top it off.
254

What Fuel to Use in Canada
Canadian fuels are blended for seasonal changes.
Diesel Type “A” fuel is blended for better cold
weather starting (below 0°F or−18°C); however,
you may notice some power and fuel economy
loss. If Type “A” fuel is used in warmer
temperatures, stalling and hard starting may
occur. Diesel Type “B” fuel is blended for
temperatures above 0°F (−18°C).
It is important that diesel-powered trucks are
refueled only with ultra low-sulfur fuel. The
emission control system requires the use of diesel
fuel with ultra low-sulfur (0.0015% by weight, or
15 ppm, maximum) content. Both ultra low-sulfur
and higher sulfur diesel fuels are available in
the United States. Use of fuels with higher-sulfur
content will affect the function of the emission
components and may cause reduced performance,
excessive smoke, and unpleasant odor.
At a minimum, the diesel fuel you use should
meet the latest version of specification
CAN/CGSB-3.517 (Low Sulfur Diesel) in Canada.
In addition, the Engine Manufacturers Association
(EMA) has identified properties of an improved
diesel fuel for better engine performance and
durability (FQP-1A). Diesel fuels corresponding tothe EMA description could provide better starting,
less noise, and better vehicle performance. If
there are questions about the fuel you are using,
contact your fuel supplier.
If your vehicle has the 6.6L engine, it is acceptable
to use diesel fuel containing up to 5% biodiesel
(B5), but the final blended fuel must meet the same
specification, CAN/CGSB-3.517 (Low Sulfur Diesel)
in Canada, as other fuels used in your vehicle, and
the biodiesel used for making this fuel must meet
the latest version of ASTM specification D 6751.
Biodiesel is produced from vegetable oils or animal
fat that have been chemically modified to reduce
the possibility of damage to your fuel system and
engine. Higher concentration (i.e., greater than B5)
biodiesel-containing fuels or the use of unmodified
bio-oils blended into diesel fuel at any concentration
is not recommended and could damage your fuel
system and engine. Such damage would not be
covered by your warranty. If there are questions
about the biodiesel-containing fuels you are using,
contact your fuel supplier.
255

Very Cold Weather Operation
Follow the instructions listed previously under the
heading “What Fuel to Use.”
Notice:Never use home heating oil or
gasoline in your diesel engine. They can cause
engine damage.
In cold weather, your fuel filter may become
clogged (waxed). To unclog it, move the vehicle to
a warm garage area and warm the filter to
between 32°F and 50°F (0°C to 10°C). You will
not need to replace it. Additional information on the
fuel filter follows.
Water in Fuel
{CAUTION:
Diesel fuel containing water is still
ammable. You could be burned. If you
ever try to drain water from your fuel,
keep sparks, ames and smoking
materials away from the mixture.Notice:If there is water in your diesel fuel
and the weather is warm or humid, fungus and
bacteria can grow in the fuel. They can
damage your fuel system. A diesel fuel biocide
can be used to sterilize your fuel system.
However, your fuel system may still need to be
cleaned. Your dealer can advise you of the
appropriate solution.
If your fuel tank needs to be purged to remove
water, see your dealer or a qualied technician.
Improper purging can damage your fuel system.
Sometimes, water can be pumped into your fuel
tank along with your diesel fuel. This can happen if
a service station does not regularly inspect and
clean its fuel tanks, or if it gets contaminated fuel
from its suppliers.
If this happens, the
water-in-fuel light, if
equipped, will come on
in the instrument panel.
If it does, the water must
be drained. Your dealer
can show you how to
do this.
256

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, seeEngine Oil
(Caterpillar
®Diesel Engine) on page 268or
Engine Oil (Gasoline Engine) on page 268or
Engine Oil (DURAMAX
®/Isuzu Diesel
Engine) on page 272.6. 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
®/Isuzu 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.
258

Priming the 7.8L Isuzu 6H Diesel Engine
If your vehicle is equipped with the 7.8L Isuzu 6H
diesel engine, use the following procedure to
prime the engine:
1. Make sure there is fuel in the fuel tank.
2. Make sure the specified fuel filter is properly
installed.
3. Make sure the fuel lines are securely
connected.
4. Make sure the fuel filter is cool to the touch.
5. Use a clean cloth to remove dirt and oil
from the fuel filter head and breather valve.6. Use the palm of your hand to repeatedly
press and release the plunger (1) at the
top of the fuel filter priming pump. Continue
until the plunger resistance becomes firm. This
may take from 20 to 100 times, depending
upon fuel tank location.
7. Turn the fuel filter breather valve screw (2)
counterclockwise several turns to open the
breather valve.
8. Use the palm of your hand to repeatedly
press and release the plunger (1) at the
top of the fuel filter priming pump until fuel
begins to seep from the breather valve.
9. Tighten the fuel filter breather screw (2) to the
specified torque, 4.9
Y(43 in. lbs).
10. Use the palm of your hand to press and
release the plunger (1) at the top of the
fuel filter priming pump about 20 more times.
This sends fuel to the engine.
11. Use a clean cloth to remove any fuel from the
fuel filter and surrounding area.
12. Start the engine and allow it to idle for a
few minutes.
13. Check the fuel filter for leakage.
