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.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 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 2,000 miles 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 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.
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.
