ESCRIPTIONS — DIESEL

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 114.
The display always shows one of the main
menu items 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 opera -
tion and emissions compliance. If some -
thing is wrong with the gauge, a DEF
Warning Message or Malfunction Indicator
Light (MIL) will be displayed Ú page 125.
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 repre
-
sented in the gauge. You may not see any
movement in the reading – even after
driving up to 2,000 miles (3,219 km) 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 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.
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.
INSTRUMENT CLUSTER DISPLAY
Your vehicle will be equipped with an instrument
cluster display, which offers useful information to
the driver. With the ignition in the OFF mode,
opening/closing of a door will activate the display
for viewing, and display the total miles, or
kilometers, in the odometer. Your instrument
cluster display is designed to display important
information about your vehicle’s systems and
features. Using a driver interactive display located
on the instrument panel, your instrument cluster
display can show you how systems are working and
give you warnings when they are not. The steering
wheel mounted controls allow you to scroll through
the main menus and submenus. You can access
the specific information you want and make
selections and adjustments.
