AdBlue consumption depends on driving style, which is why filling may be necessary between the normal service intervals. If the AdBlue tank is allowed to drain completely then it will no longer be possible to start the car.
Never run the AdBlue tank dry. Fill the tank in good time before it is empty.
If the tank is run dry, it will not be possible to start the engine after it is switched off – not the regular way or using aids.
The only way to be able to restart after driving the tank empty is to refill AdBlue of specified quality, with the minimum being the quantity shown in the driver display.
Checking AdBlue level
Open the Car Status app in the app view.
Press Status to show the AdBlue level.
Graphic for AdBlue level in the centre display.
Each cursor represents approx. 25% of a full tank.
When less than 25 % of the tank remains available, the colour of the remaining cursor changes to amber, and at less than 10 % it turns red.
When the AdBlue level starts to become low, a symbol illuminates in the driver display and the AdBlue level low message is shown.
Open the fuel filler flap with a gentle press on the rear of the flap.
Open the blue cover for the smaller filler pipe intended for AdBlue.
Fill with AdBlue of the correct qualityISO 22241.
Do not overfill the tank. The amount of AdBlue that can be filled is shown in the app Car Status.
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.
Wipe away any spilled AdBlue.
Exercise caution to prevent AdBlue from coming into contact with the car's paintwork. If it does, rinse with plenty of water since the fluid can affect the paintwork.
