GETTING TO KNOW YOUR INSTRUMENT PANEL 89
DIESEL INSTRUMENT CLUSTER
1. Tachometer
Indicates the engine speed in revolutions
per minute (RPM x 1000).
2. Instrument Cluster Display
When the appropriate conditions exist,
this display shows the instrument cluster
display messages Ú page 90.
Premium Instrument Cluster Display
The display always shows one of the main
menu item after ignition on.
3. Speedometer
Indicates vehicle speed.
4. 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 Diesel Exhaust
Fluid (DEF) Warning Messages.
5. 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 DEF tank on these vehicles is designed
with a large amount of full reserve. So the
level sensor will indicate a full reading even
before the tank is completely full. To put it
another way, there’s additional storage
capacity in the tank above the Full mark
that’s not represented in the gauge. You may
not see any movement in the reading – even
after driving up to 200 miles (321 kilome-
ters) in some cases.
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 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.
