Press home button and then slide to the search icon. You should be able to see "show more cards" button. If not then slide down to the very bottom of the screen, you will see three dots in the bottom-right corner. Click this, open Settings dialog and then click on Google Now tab. You will have the option to turn it on then. If it's not appearing check also TOP RIGHT corner of the screen for a switch available.
