A - DEF Indicator Gauge

B - Low Level Mark

C - DEF Tank Cap

Fill DEF tank every time tractor is refueled. If this cannot be done, monitor DEF indicator gauge (A) on instrument cluster and refill as necessary. To avoid drastic changes in tractor performance, always keep DEF level above low level mark (B) on the DEF indicator gauge.

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

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 (C) and area around cap and filler neck to reduce chance of contaminating DEF.
  3. Remove DEF tank cap.
  4. Using funnel, carefully pour DEF in 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 tank and rinse with distilled water, then refill tank.
