DEF freezes at a temperature of approximately
12.2 °F (-11 °C). The vehicle is equipped with
a DEF preheating system at the factory. This
means that winter operation is also ensured
for temperatures below 12.2 °F (-11 °C). If
you re ll DEF at temperatures below 12.2 °F
(-11 °C), the DEF level in the instrument clus-
ter may not be displayed correctly. If the DEF
is frozen, drive for at least 20 minutes and
then park the vehicle for a minimum of 30 sec-
onds, so that the level is correctly displayed. In
extreme winter conditions, the time needed to
detect the amount topped up may be consid-
erably longer. Park the vehicle in a warm
garage to speed up this process.

Ensure the connection between the re ll con-
tainer and vehicle ller neck does not drip.
