LUSTER DESCRIPTIONS

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 89.
The display always shows one of the main
menu item after the ignition is placed 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. Immediate
service should be obtained from an autho
-
rized 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 oper -
ating 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.
NOTE:The Instrument Cluster Warning Indicators will illu -
minate briefly for a bulb check when the ignition is
first cycled.
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 368.
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.

1. Temperature Gauge

The temperature gauge shows engine
coolant temperature. Any reading within
203°F - 230°F (95°C - 110°C) indicates
that the engine cooling system is operating
satisfactorily.
The 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. 2. Speedometer
Indicates vehicle speed.
3. Fuel Gauge
The pointer shows the level of fuel in the
fuel tank when the Keyless Push Button
Ignition is in the ON/RUN position.
 The fuel pump symbol points to
the side of the vehicle where the
fuel door is located.
4. Tachometer
Indicates the engine speed in revolutions

5. Instrument Cluster Display
The instrument cluster display features a

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 89.
The display always shows one of the main
menu item after the ignition is placed 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. More informa -
tion 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 kilometers) 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.
NOTE:The Instrument Cluster Warning Indicators will illu -
minate briefly for a bulb check when the ignition is
first cycled.
