Information Displays

Driver Information

Center (DIC)

The DIC is in the instrument cluster.
The DIC comes on when the ignition
is on.
A diesel vehicle may have the
following additional DIC menu items:
Exhaust Fluid Level : The Diesel
Exhaust Fluid (DEF) level will be
displayed as either OK, XX%,
or LOW.
When LOW appears on the display,
add DEF as soon as possible. See
Diesel Exhaust Fluid 0 39.
Fuel Filter Life Remaining : This
display shows an estimate of the
fuel filter's remaining useful life.
If 90% Fuel Filter Life Remaining is
displayed, it means 90% of the
current fuel filter life remains. The
fuel filter life system will alert when
to change the fuel filter on a
schedule consistent with your
driving conditions.
Instruments and Controls
When the remaining fuel filter life is
low, the CHANGE FUEL FILTER
message will appear on the display.
Change the fuel filter as soon as
possible.
Fuel Filter Life Reset : Reset the
Fuel Filter Life Remaining display
after each fuel filter change. It will
not reset itself. Also, be careful not
to reset the display at any time other
than when the fuel filter has just
been changed because it cannot be
reset accurately until the next fuel
filter change. The fuel filter life will
change to 100% when the system
has been reset. To reset the system,
press and hold the set/reset button,
or the trip odometer reset stem if
there are no DIC buttons, for
two seconds while Fuel Filter Life
Remaining is displayed on the DIC.
