DEF Tank Inlet Screen — Removal
CAUTION: Avoid possible personal injury. In case of DEF contact,
immediately flush eyes with large amounts of water for a minimum of
15 minutes. Reference the Materials Safety Data Sheet (MSDS)
for additional information. Do not ingest DEF. In the
event DEF is ingested, contact a physician immediately. Reference
the Materials Safety Data Sheet (MSDS) for additional information.
IMPORTANT: Avoid corrosion of vehicle parts or surfaces. If
DEF is spilled or contacts any surface other than the storage tank,
immediately clean the surface with clear water. DEF is corrosive to
painted and unpainted metallic surfaces and can distort some plastic
and rubber components. Spilled DEF, if left to dry or
if only wiped away with a cloth, will leave a white residue. Improperly
cleaned DEF spill may interfere with diagnosis of Selective Catalytic
Reduction (SCR) system leakage problems.
