NOTE:
•
The gauge may take up to five seconds to update after
adding a gallon or more of Diesel Exhaust Fluid (DEF) to
the DEF tank. If you have a fault related to the DEF
system, the gauge may not update to the new level. See
an authorized dealer for service.
•
The DEF gauge may also not immediately update after a
refill if the temperature of the DEF fluid is below 12F
(-11C). The DEF line heater will possibly warm up the
DEF fluid and allow the gauge to update after a period
of run time. Under very cold conditions, it is possible
that the gauge may not reflect the new fill level for
several drives.
