GETTING TO KNOW YOUR INSTRUMENT PANEL 99
MIDLINE INSTRUMENT CLUSTER
D
ESCRIPTIONS — DIESEL ENGINE
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 104.
The display always shows one of the main menu
item after ignition is placed on.
4. Oil Pressure Gauge
The pointer should always indicate some oil pres-
sure when the engine is running. A continuous
high or low reading under normal driving condi-
tions may indicate a lubrication system malfunc-
tion. Immediate 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 information is
available in the instrument cluster display section
under the heading of DEF Warning Messages.
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 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.
7. Fuel Gauge
The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN posi-
tion.
The fuel pump symbol points to the
side of the vehicle where the fuel filler
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.
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.
