Fuel System Cautions
NOTE:
Intentional tampering with the emissions
control system can result in civil penalties being
assessed against you.
Carbon Monoxide Warnings
FUEL REQUIREMENTS – DIESEL ENGINE
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.
Use good quality diesel fuel from a reputable
supplier in your vehicle. 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 performance. 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.
CAUTION!
Follow these guidelines to maintain your vehi-
cle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can
impair engine performance and damage
the emissions control system.
An out-of-tune engine or certain fuel or igni-
tion malfunctions can cause the catalytic
converter to overheat. If you notice a
pungent burning odor or some light smoke,
your engine may be out of tune or malfunc-
tioning and may require immediate service.
Contact an authorized dealer for service
assistance.
The use of fuel additives, which are now
being sold as octane enhancers, is not
recommended. Most of these products
contain high concentrations of methanol.
Fuel system damage or vehicle perfor-
mance problems resulting from the use of
such fuels or additives is not the responsi-
bility of the manufacturer and may void or
not be covered under the New Vehicle
Limited Warranty.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to pre-
vent 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 explo-
sive when mixed with diesel fuel.
