A single press of the (underneath) button will turn the DIS on/off.
To reset you need to hold the button for a moment.
Need then to press the button at the end of the stork to move through the different items and cancel each in turn by holding the button underneath for a moment.
There are two items you cannot cancel i.e. mpg and miles (to refill).
Hope this helps!
