The Front Wheel will naturally swivel unless one of the two front wheel locks is operated
At the side of the seat near the top on the right (just behind the sun hood) is an operating lever to lock the front wheel under the pushchair. When operated the end of the lever is nearest the handle.
To release the lever slide the grey catch and move the lever downwards. see below
On the front wheel fork is a second locking button to lock the front wheel forwards. When this locking button is operated the front wheel will lock forwards BUT the locking button will then be unhelpfully concealed on the reverse of the front fork.
To release the button reach behind the front fork and de-activate it.
