BASE / MIDLINE INSTRUMENT CLUSTER DESCRIPTIONS — DIESEL
Tachometer
Indicates the engine speed in revolutions per minute (RPM x 1000).
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.
Instrument Cluster Display
When the appropriate conditions exist, this display shows the instrument cluster display messages page 114.
1 – Instrument Cluster Display Controls 2 – Instrument Cluster Display Screen
The display always show one of the main menu item after ignition on.
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.
Speedometer
Indicates vehicle speed.
Fuel Gauge
The gauge 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 door is located.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 compli- ance. If something is wrong with the gauge, a DEF Warning Message or Malfunction Indicator Light (MIL) will be displayed page 123.
The gauge may take up to five seconds to update after adding a gallon or more of Diesel Exhaust Fluid 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 12°F (-11°C). The DEF line 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. 3
Outside temperature can affect DEF consumption. In cold conditions, 12°F
(-11°C) and below, the DEF gauge needle can stay on a fixed position and may not move for extended periods of time. This is a normal function of the system.
