If you notice the AdBlue warning light on the instrument panel while driving, and a message indicates that you need to top up the additive, you will not be able to start the vehicle after a certain number of miles. The onboard computer is alerting you to the low level of the additive in the tank, so to turn off this warning light, you need to refill the additive.

To do this, purchase a canister of AdBlue and open the fuel flap where next to the fuel tank cap, you will find the blue cap for the additive tank. Once you have topped up, check that the warning light on the instrument panel has turned off.
