A - Diesel Exhaust Fluid (DEF) Level Indicator

B - DEF Tank Cap

CAUTION: Avoid serious injury from falling. Do not stand on fuel tank.

Diesel Exhaust Fluid (DEF) contains urea. Do not get the substance in eyes. In case of contact, immediately flush eyes with large amounts of water for a minimum of 15 minutes. Do not take internally. In event DEF is ingested, contact a physician immediately. Reference Materials Safety Data Sheet (MSDS) for additional information.

IMPORTANT: Never put DEF in diesel fuel tank, or diesel fuel in DEF tank.

NOTE: Spilled DEF, if left to dry or if only wiped away with a cloth, will leave a white residue. Aside from cosmetic issues, an improperly cleaned DEF spill may interfere with diagnosis of Selective Catalytic Reduction (SCR) system leakage problems.

DEF tank capacity is 29.5 L (7.8 gal.).

Fill tank every time machine is refueled. If this cannot be done, monitor Diesel Exhaust Fluid (DEF) level indicator (A) on primary display unit and refill as necessary. To avoid drastic changes in machine performance, always keep DEF level above topmost red mark on level indicator. See Selective Catalytic Reduction (SCR) System in Operating the Machine section.

To fill DEF tank:

1. Before using containers, funnels, etc. to dispense DEF, wash and rinse items thoroughly with distilled water to remove contaminants.
2. Wipe DEF tank cap (B) and areas around filler neck to reduce chance of contaminating DEF.
3. Remove cap.
4. Using funnel, carefully pour DEF into tank, watching level through filler neck.
5. Securely tighten DEF tank cap.
6. Carefully clean any spills, using distilled water only.

If an unapproved fluid, such as diesel fuel, or engine coolant is added to vehicle DEF tank, drain and rinse tank. (See Drain and Flush Diesel Exhaust Fluid (DEF) Tank in Engine and Drive Train section of this manual.)
