DIESEL INSTRUMENT CLUSTER

1. Tachometer

Indicates the engine speed in revolutions
per minute (RPM x 1000).
2. Engine Coolant Temperature

This gauge shows the engine coolant tempera -
ture. 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
When the appropriate conditions exist, this
display shows the instrument cluster
display messages Ú
page 81.
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 some 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. 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 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.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.
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.

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
