Fuel and DEF level
• Scale level appears green when levels are between full and 1/8 and appears red when levels are between 1/8
and empty.
• When the levels are in the green range, switches (icons) appear white. When the levels are in the red range,
switches (icons) turn black and are backlit with amber light. The amber lights blink when the tank level is depleted
to 1/16.
IMPORTANT:
Running out of DEF will cause the engine to derate and will eventually limit throttle to idle.
