Checking and filling AdBlue

Check the AdBlue level regularly and top up if the message for low AdBlue level is shown in the driver display. The emissions system continuously monitors the level, quality and dosage of AdBlue. If a fault arises, a message is shown in the driver display. Depending on driving style, outside temperature and the operating temperature of the system, filling must also be performed several times between service intervals. AdBlue is topped up in a separate filler pipe behind the fuel filler flap.

If the Adblue tank becomes completely empty then it will be no longer possible to start the car. To be able to start the car again, the tank must be filled with AdBlue of the specified quality, at the minimum quantity indicated in the driver display. Avoid driving the tank completely empty and refill in good time.

AdBlue Filling

When the AdBlue level starts to become low, a symbol illuminates in the driver display and the message AdBlue level low is shown.
1. Open the fuel filler flap by gently touching the rear part of the flap.
2. Open the blue cap for the smaller filler pipe intended for AdBlue.

3. Top up with AdBlue of the correct quality. Fill slowly, in order to avoid air pockets.

Do not overfill the tank.

When filling from the AdBlue pump at a filling station, it is advisable to use the pump adapted for passenger cars. The AdBlue pump for heavy vehicles can also be used.

Handling AdBlue
AdBlue consists primarily of water and is not flammable but should be handled with care since it can irritate the eyes and skin. Avoid inhaling vapour as well as contact with skin and eyes.

Adblue must be stored in tightly sealed original packaging at a temperature between -11 °C and 30 °C. The fluid must not be stored in direct sunlight. When it is cold outside, pay attention to the fact that the fluid freezes at -11 °C.
