Yep as above;
inflate all your tyres to the desired pressure 1st.
Then on the centre console there is a button that looks like a pair of boobs (with flattened ends!) and an exclaimation mark in the middle, I think from memory also has the word SET under it and probably nest to the ESP button.
Turn ignition on and press and hold for about 3 secs the warning light on dash will go off.
Hopefully then will stay off otherwise you have a slow puncture
