freezes at a temperature of approx‐
imately -11 °C . The vehicle is equipped with
an AdBlue
®
preheating system at the factory.
This means that winter operation is also
ensured for temperatures below -11 °C. If
you top up AdBlue
®
at temperatures below
-11 °C, the AdBlue
®
level in the instrument
cluster may not be displayed correctly. If the
AdBlue
®
is frozen, drive for at least
20 minutes and then park the vehicle for a
minimum of 30 seconds, so that the level is
correctly displayed. In extreme winter condi‐
tions, the time needed to detect the top-up
amount may be considerably longer. Park the
vehicle in a warm garage to speed up this
process.

Ensure the connection between the refill con‐
tainer and vehicle filler neck does not drip.
