The diesel fuel level is indicated at the top of the
gauge, with a low-fuel warning lamp that illuminates
when the diesel fuel level registers 1/8th of capacity.
The DEF level is indicated in the lightbar on the
lower portion of the gauge. There is a low DEF level
warning lamp that illuminates amber when the DEF
level reaches 10% of capacity. See
details of the DEF gauge functions.
