WARNING!
Diesel fuel in the presence of an ignition
source could cause an explosion. A mixture
of gasoline or alcohol with diesel fuel in-
creases this risk of explosion. Do not re-
move a fuel tank cap near an open flame.
Use only the fuel and/or additives recom-
mended for your engine. Failure to comply
may result in death, personal injury, equip-
ment or property damage.
CAUTION
Use only Ultra Low Sulfur Diesel (ULSD)
Fuel, as recommended by engine manufac-
turers. If you need further information on
fuel specifications, consult the Engine Oper-
ation and Maintenance Manual.
NOTE
For Export vehicles, the fuel gauges will not
state: ULTRA LOW SULFUR DIESEL FUEL
ONLY.
NOTE
This vehicle may be manufactured with dif-
ferent fuel systems and different draw tube
locations. Because of this and the amount of
road crown, it is recommended that you do
not operate your vehicle with less than one-
quarter of your truck’s fuel capacity. Allowing
the fuel level to go below one-quarter of ca-
pacity could result in the lack of fuel to keep
the engine running. In addition, you will want
to keep the fuel tanks at least half-full to re-
duce condensation of moisture in the tanks.
This moisture can damage the engine.

Engine, Oil Pressure
If oil pressure drops below the minimum
psi a red warning light in the gauge will turn
on, the Stop Engine light will come on and
an audible alarm tone will sound.
CAUTION
Continuing to operate your vehicle with in-
sufficient oil pressure will cause serious en-
gine damage. Failure to comply may result
in equipment or property damage.
It is important to maintain oil pressure
within acceptable limits. For further
information on engine oil and normal
operating pressures, see the Engine
Operation and Maintenance Manual. If the
oil pressure fails to rise within 10 seconds
after the engine starts, stop the engine and
determine the cause. Check the engine
manufacturer's manual for the correct oil
pressure ranges for your vehicle's engine.
If the oil pressure suddenly drops, or the
audible alarm and engine oil pressure
warning light come on while driving. For
further information on engine gauges and
operating your engine properly, refer to
Engine Maintenance material.
