GMC Terrain: Warning Lights, Gauges, and Indicators / Diesel Exhaust Fluid (DEF) Warning Light

This light, a Driver Information
Center (DIC) Message, and a chime
come on when there is an issue with
the DEF.
If the DEF issue has not been
corrected, the light will continue to
flash. The vehicle's speed may also
be limited. See Diesel Exhaust Fluid.
For the base level cluster, this light
comes on when the fuel tank is low
on fuel. The light turns off when fuel
is added. If it does not, have the
vehicle serviced...
The security light should come on
briefly as the engine is started. If it
does not come on, have the vehicle
serviced by your dealer. If the
system is working normally, the
indicator light turns off...
