Diesel Exhaust Fluid (DEF) Level Gauge

The driver display screen shows a DEF level gauge in the lower left hand corner below the fuel gauge. When the DEF level reaches 1/8th of capacity, the low DEF icon and the remaining measurement bar illuminate amber. The bar will continue to remain amber as it decreases until the DEF tank is empty, at which point only the low DEF icon will remain lit. See the chapter on Emissions and Fuel Efficiency for more details on the DEF level gauge.
