Performance is not compromised in delivering less emissions and reduced fuel consumption. In fact, the new BlueTEC engines deliver up to 6.5% more torque, contributing to your long-term success every kilometre of the way.
To function properly, BlueTEC diesel engines require AdBlue to comply with the stringent Euro 6 emissions standard and maintain the vehicle’s performance. The following is general information on AdBlue, however for further information please refer to the vehicle’s Operating Instructions, or contact an authorised Mercedes-Benz Dealer.
What is AdBlue?
AdBlue is an aqueous solution of urea and de-ionised water. AdBlue is not a fuel additive and must not be added to the fuel tank.
Where does AdBlue need to go in the vehicle?
AdBlue must only be filled into the vehicle’s separate AdBlue tank. The AdBlue filler neck is located behind the fuel filler flap near the passenger door.
How often does AdBlue need to be used?
Similar to fuel consumption, AdBlue use can vary depending on your driving style and the vehicle’s operating conditions. On average, 1–1.5litres of AdBlue should last approximately 1,000 kilometres, however this may vary.
If the supply of AdBlue is almost empty, the display shows the Refill
AdBlue message in good time. If you continue driving without refilling the AdBlue tank, you will only be able to drive the vehicle the maximum distance shown.
If you operate the vehicle without AdBlue, the emissions standard will no longer be met, and the engine management system subsequently prevents the engine being started again until AdBlue is added to the AdBlue tank. Therefore top up the AdBlue tank regularly during vehicle operation or, at the latest, after receiving the first warning message via the on-board computer.
