Make sure the vehicle is level to assure an accurate fuel level reading. The fuel tank
is capable of holding 45 gallons (171 liters) of diesel fuel.
Fuel Types

diesel fuel gives the best fuel economy and performance under most operating
conditions. Fuels with Cetane ratings higher than 40 may be needed in higher
altitudes or extremely low ambient temperatures to prevent misfiring and excessive
smoke.
ï When operating at temperatures above 32 F (0 C), use standard #2
diesel fuel.
ï When operating at temperatures below 32 F (0 C), use a blend of #1 &
#2 diesel fuels, most commonly known as ìwinterizedî #2 diesel.

Engine fuel is flammable and can cause a fire or an
explosion. Keep sparks and open flames away from the vehicle and DO
NOT use smoking materials while refueling.
