NOTE:
• Use of Climatized ULSD Diesel Fuel or Number 1
ULSD Diesel Fuel results in a noticeable decrease in
fuel economy.
• Climatized ULSD Diesel Fuel is a blend of Number 2
ULSD and Number 1 ULSD Diesel Fuels which re-
duces the temperature at which wax crystals form in
fuel.
NOTE:
This engine requires the use of “Ultra Low
Sulfur Diesel Fuel.”
Use of incorrect fuel could result in
exhaust system damage. Refer to “Fuel Requirements” in
this section for further details on fuel recommendations.
Battery Blanket Usage
A battery loses 60% of its cranking power as the battery
temperature decreases to 0°F (-18°C). For the same de-
crease in temperature, the engine requires twice as much
power to crank at the same RPM. The use of 120 VAC
powered battery blankets will greatly increase starting
capability at low temperatures. Suitable battery blankets
are available from your authorized Mopar
dealer.
Engine Starting Procedure
WARNING!
NEVER pour fuel or other flammable liquid into the
air inlet opening in an attempt to start the vehicle.
This could result in a flash fire causing serious
personal injury.
1. The gear selector must be in the “N” (Neutral) or “P”
(Park) position before you can start the engine.
2. Turn the ignition key to the ON position.
