STARTING AND OPERATING 71 CAUTION! • To avoid DEF spillage, and possible damage to the DEF tank from overfilling, do not "top off" the DEF tank after filling. • DO NOT OVERFILL. DEF will freeze below 12ºF (-11ºC). The DEF system is designed to work in temperatures below the DEF freezing point, however, if the tank is overfilled and freezes, the system could be damaged. • When DEF is spilled, clean the area immediately with water and use an absorbent material to soak up the spills on the ground. • Do not attempt to start your engine if DEF is accidentally added to the diesel fuel tank as it can result in severe damage to your engine, including but not limited to failure of the fuel pump and injectors. 3. Stop filling the DEF tank immediately when any of the following happen: DEF stops flowing from the fill bottle into the DEF fill inlet, DEF splashes out the fill inlet, or a DEF pump nozzle automatically shuts off. 4. Reinstall cap onto DEF fill inlet. 4
