WARNING!

cause electrocution.
NOTE: The block heater will require 110 Volts AC and
6.5 Amps to activate the heater element.
FUEL REQUIREMENTS
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 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.
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.
