AdBlue® is an aqueous solution which helps to reduce the nitrous oxides in diesel vehicle exhaust by up to 90 %.
Selective catalytic reduction (SCR) transforms the nitrous oxides in the exhaust gas system with the aid of AdBlue® into its environmentally-friendly components, nitrogen and water. AdBlue® consists of aqueous urea and is completely non-toxic.
Nice and clean.

AdBlue® is odourless and non-toxic and can in future be topped up by the driver themself – either from top-up containers or at special pumps available at an ever-increasing number of service stations. This is possible all over the world, as AdBlue® is based on uniform standards.
To reduce the emission of nitrous oxides further, Mercedes-Benz uses selective catalytic reduction (SCR) as a sustainable and effective way of protecting the environment.
SCR technology reduces the emission of nitrous oxides by up to 90 % by transforming the nitrous oxides in exhaust gas into its environmentally-friendly components, nitrogen and water, with the aid of AdBlue®.
AdBlue® is an odourless, non-toxic urea solution which is automatically added to the exhaust gas system. Mercedes-Benz has been using SCR technology since 2009 for BlueTEC diesel models, and this has proved successful for a long time in the commercial vehicle sector. From 2014, Mercedes-Benz will introduce SCR technology with AdBlue® as standard for other diesel passenger car models.
A new development is that the AdBlue® tanks can, in future, be topped up by the driver themself – either from top-up containers or at special pumps available at an ever-increasing number of service stations and garages. This is possible all over the world, as AdBlue® is based on uniform ISO and DIN quality standards everywhere. In the commercial vehicle sector, the necessary pumps are already established, but these are generally not suitable for cars. All Mercedes-Benz service centres will continue to offer the AdBlue® top-up service and will continue to stock AdBlue® top-up containers.
If the AdBlue® tank is empty, the vehicle can no longer be driven. When the AdBlue® level starts to drop, the instrument cluster gives the driver a first warning, similar to a warning about a low fuel level, so that there is enough time to refill.
AdBlue® can be used in almost all weather conditions. For winter temperatures below -11 °C, the cars have heating systems which reliably ensure the operation of the SCR system. The AdBlue® pumps are also heated in cold countries where sub-zero temperatures require it.
Vehicles with AdBlue® are particularly eco-friendly. They already conform to the new Euro 6 emissions standard which is due to come into force in September 2014.
