NOTE:
Intentional tampering with the emissions
control system can result in civil penalties being
assessed against you.
Carbon Monoxide Warnings
FUEL REQUIREMENTS – DIESEL ENGINE
Use good quality diesel fuel from a reputable
supplier in your vehicle. Federal law requires
that you must fuel this vehicle with Ultra Low
Sulfur Highway Diesel fuel (15 ppm Sulfur
maximum) and prohibits the use of Low Sulfur
Highway Diesel fuel (500 ppm Sulfur maximum)
to avoid damage to the emissions control
system.
For most year-round service, No. 2 diesel fuel
meeting ASTM (formerly known as the American
Society for Testing and Materials) specification
D-975 Grade S15 will provide good perfor -
mance. If the vehicle is exposed to extreme cold
(below 20°F or -7°C), or is required to operate
at colder-than-normal conditions for prolonged
periods, use climatized No. 2 diesel fuel or
dilute the No. 2 diesel fuel with 50% No. 1 diesel
fuel. This will provide better protection from fuel
gelling or wax-plugging of the fuel filters. Diesel fuel is seldom completely free of water.
To prevent fuel system trouble, drain the accu
-
mulated water from the fuel/water separator
using the fuel/water separator drain provided
on both fuel filters. If you buy good quality fuel
and follow the cold weather advice above, fuel
conditioners should not be required in your
vehicle. If available in your area, a high cetane
“premium” diesel fuel may offer improved
cold-starting and warm-up performance.
Fuel Specifications
The Cummins® Turbo Diesel engine has been
developed to take advantage of the high energy
content and generally lower cost No. 2 Ultra Low
Sulfur diesel fuel or No. 2 Ultra Low Sulfur clima-
tized diesel fuels. Experience has shown that it
also operates on No. 1 Ultra Low Sulfur diesel
fuels or other fuels within specification.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in
a closed area, such as a garage, and never
sit in a parked vehicle with the engine
running for an extended period. If the
vehicle is stopped in an open area with the
engine running for more than a short
period, adjust the ventilation system to
force fresh, outside air into the vehicle.
Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with
all side windows fully open.WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable under
certain conditions and hazardous or
explosive when mixed with diesel fuel.
CAUTION!
If the “Water in Fuel Indicator Light” remains
on, DO NOT START engine before you drain
the water from the fuel filter(s) to avoid
engine damage. Refer to “Draining Fuel/
Water Separator Filter” in “Servicing And
Maintenance” for further information.
