As the DEF tank becomes low on
fluid, warnings begin with
approximately 1 600 km (1,000 mi)
of remaining range. These warnings
will increase as the tank becomes
empty. Once the tank is empty, the
vehicle speed will be limited. If there
is an issue with the quality of the
fluid or the exhaust fluid system,
warnings will be displayed in the
Driver Information Center (DIC).
