GETTING TO KNOW YOUR INSTRUMENT PANEL 111
5. Speedometer
Indicates vehicle speed.
6. Fuel Gauge
The gauge 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 door
is located.
7. 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 Ú page 123.
NOTE:
The gauge may take up to five seconds to
update after adding a gallon or more of
Diesel Exhaust Fluid 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 12°F (-11°C). 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.
Outside temperature can affect DEF
consumption. In cold conditions, 12°F
(-11°C) and below, the DEF gauge needle
can stay on a fixed position and may not
move for extended periods of time. This is a
normal function of the system.
