6. Temperature Gauge
The gauge pointer shows engine coolant
temperature. The pointer positioned
within the normal range indicates that
the engine cooling system is operating
satisfactorily.
The gauge pointer will likely indicate a
higher temperature when driving in hot
weather, up mountain grades, or when
towing a trailer. It should not be allowed
to exceed the upper limits of the normal
operating range. 7. Fuel Gauge
The pointer shows the level of fuel in
the fuel tank when the ignition is in the
ON/RUN position.
 The fuel pump symbol points
to the side of the vehicle where
the fuel door is located.
WARNING!

A hot engine cooling system is dangerous.
You or others could be badly burned by steam
or boiling coolant. It is recommended to call an
authorized dealer for service if your vehicle
overheats. If you decide to look under the hood
yourself, Follow the warnings under the Cooling
System Pressure Cap paragraph
Ú
page 383.

CAUTION!

Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge
reads “H,” pull over and stop the vehicle. Idle
the vehicle with the air conditioner turned off
until the pointer drops back into the normal
range. If the pointer remains on the “H,” turn
the engine off immediately and call an
authorized dealer for service.

4. Oil Pressure Gauge
The pointer should always indicate some
oil pressure when the engine is running.
A continuous high or low reading under
normal driving conditions may indicate a
lubrication system malfunction. Imme-
diate service should be obtained from an
authorized dealer.
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 compliance. If
something is wrong with the gauge, a DEF
Warning Message or Malfunction Indicator
Light (MIL) will be displayed. More informa
-
tion 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 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.

 The fuel pump symbol points

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

INSTRUMENT CLUSTER DISPLAY

Your vehicle is 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.
