Fig. 1, Fuel/DEF Gauge

The fuel and DEF levels can be measured in a dual purpose fuel/DEF level gauge. See Fig. .

The diesel fuel and DEF levels are indicated on the gauge. A low fuel warning lamp illuminates amber when the diesel fuel level registers 1/8th of capacity. The low DEF warning lamp illuminates amber when the DEF level reaches 10 percent of capacity. See Greenhouse Gas Emissions and Fuel Consumption Standards Emissions and Fuel Efficiency for details of the DEF gauge functions.
