CAUTION! (Continued)
• Never add anything other than DEF to the 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) will contaminate 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 is has only been used for adding DEF. MOPAR
provides an attachable nozzle with its DEF for this
purpose.
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.
