What happens if my car runs out of AdBlue?

Your car will warn you when the range for the AdBlue® tank is 2400 km. What happens after the 2400 km warning is different for each brand, so please check your owner’s manual to find out what applies to your vehicle.

For example, a Opel Zafira Tourer will warn you at a range of 2400 km. Then, the car will limit your maximum speed to 100 km/h at a range of 900 km. The car will eventually limit the maximum speed to 50 km/h and it will warn you that the engine will not restart once the engine is turned off.
Make sure you carry an emergency supply on board or continue to the next distribution point without shutting down your engine.
