Never add anything other than DEF to the Extra care should be taken when filling with portable containers to avoid overfilling. Note the level of the DEF gauge in your instrument cluster. You may safely add a maximum of 2 gallons (7.5 liters) of DEF from portable containers when your DEF gauge is reading Ѕ full.

tank – especially any form of hydrocarbon such as diesel fuel, fuel system additives, gasoline, or any other petroleum-based product. Even a very small amount of these, less than 100 parts per million or less than 1 oz. per 78 gallons (295 liters) will contami nate the entire DEF system and will require replacement. If owners use a container, funnel or nozzle when refilling the tank, it should either be new or one that has only been used for adding DEF. Mopar® provides an attachable nozzle with its DEF for this purpose. After the indication appears on the instrument cluster display Ъ page81 fill the DEF tank with no more than 6 gallons (22 liters).
CAUTION! G ROSS V EHICLE W EIGHT R ATING (GVWR) To avoid DEF spillage, and possible damage to the DEF tank from overfilling, do not “top off” the DEF tank after filling. The GVWR is the total permissible weight of your vehicle including driver, passengers, vehicle, options and cargo. The label also specifies maximum capacities of front and rear axle systems (GAWR). Total load must be limited so GVWR and front and rear GAWR are not exceeded. P AYLOAD DO NOT OVERFILL. DEF will freeze below 12єF (-11єC). 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.
Stop filling the DEF tank immediately if DEF splashes or wells back in the filler neck. When DEF is spilled, clean the area immedi Reinstall cap onto DEF filler tube. Filling The Def Tank In Cold Climates ately with water and use an absorbent mate rial to soak up the spills on the ground. Since DEF will begin to freeze at 12°F (-11°C), your vehicle is equipped with an automatic DEF heating system. This allows the DEF injection system to operate properly at temperatures below 12°F (-11°C). If your vehicle is not in operation for an extended period of time with temperatures below 12°F (-11°C), the DEF in the tank may freeze.
If the tank is overfilled and freezes, it could The payload of a vehicle is defined as the allowable load weight a truck can carry, including the weight of the driver, all passengers, options and cargo. 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.
