108 GETTING TO KNOW YOUR INSTRUMENT PANEL
5. Speedometer
Indicates vehicle speed.
6. Diesel Exhaust Fluid (DEF) Gauge
The DEF Gauge displays the actual level
of Diesel Exhaust Fluid in the DEF tank.
DEF is required to maintain normal
vehicle operation and emissions compli-
ance. If something is wrong with the
gauge, a DEF Warning Message or
Malfunction Indicator Light (MIL) will be
displayed. More information is available
in the instrument cluster display section
under the heading of DEF Warning
Messages.
7. Fuel Gauge
The pointer shows the level of fuel in the
fuel tank when the ignition switch is in
the ON/RUN position.
The fuel pump symbol points
to the side of the vehicle where
the fuel filler door is located.
NOTE:
The gauge may take up to five seconds to
update after adding a gallon or more of 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 39°F (4°C). The DEF tank
heater will 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.
