May be similar to a GM - the first message on the GM is:
The Driver Information Center (DIC) will provide the driver with current information about the DEF system operation and range. These messages include:
EXHAUST FLUID RANGE: 1000 MI
EXHAUST FLUID RANGE: 300 MI
Below 300 miles (500 km) of range, the range message or speed limiting messages will appear every time the vehicle is started.
TIP: DEF should be added prior to receiving an Exhaust Fluid Empty DIC message; however, it may take several miles of driving for the DIC message to update.
If the Exhaust Fluid Empty message is displayed:
When refilling, more than one gallon of DEF must be added to release the vehicle from speed limitation.
Wait for up to 30 seconds with the engine running for the Exhaust Fluid Empty DIC message to clear.
If the vehicle is driven prior to the Exhaust Fluid Empty message clearing, the vehicle will still be speed limited.
If the Exhaust Fluid Empty message clears while driving, the vehicle must be brought to a complete stop to release the speed limitation.
