AdBlue® is available at numerous filling stations via AdBlue® filling pumps.
alternatively, AdBlue® is available at qualified specialist workshops, e.g. a Mercedes-Benz Service Centre, and at numerous filling stations as an AdBlue® refill canister or AdBlue® refill bottle.
AdBlue® freezes at a temperature of approximately -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 conditions, 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 container and vehicle filler neck does not drip.
