1. Tachometer

Indicates the engine speed in revolutions
per minute (RPM x 1000).
2. Voltmeter
When the vehicle is in the RUN state, the
gauge indicates the electrical system
voltage. The pointer should stay within
the normal range if the battery is
charged. If the pointer moves to either
extreme left or right and remains there
during normal driving, the electrical
system should be serviced. 3. Instrument Cluster Display
When the appropriate conditions exist,
this display shows the instrument cluster
display messages Ú
page 90.

Base Instrument Cluster Display

The display always shows one of the main
menu item after ignition on. 4. Oil Pressure Gauge
The pointer should always indicate the
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. 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.

2. Engine Coolant Temperature
This gauge shows the engine coolant
temperature. The gauge pointer will likely
show higher temperatures when driving
in hot weather, up mountain grades, or in
heavy stop and go traffic. If the red
Warning Light turns on while driving,
safely bring the vehicle to a stop, and
turn off the engine. DO NOT operate the
vehicle until the cause is corrected. 3. Instrument Cluster Display

CAUTION!

Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge
reads greater “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.
