STARTING AND OPERATING 283 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 reduces 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 decrease in temperature, the engine requires twice as much power to crank at the same RPM. The use of 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 shift lever must be in the NEUTRAL or PARK position before you can start the engine. 2. Turn the ignition key to the ON position. 3. Watch for the "Wait To Start Light" in the instrument cluster. Refer to "Instrument Cluster" in Section 4 of this manual. It will glow for two to ten seconds or more, 5
