AdBlue® can be topped up at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre.
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 amount topped up 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.
