The pad and the metal 3 spoke horn ring simply screw off counter-clockwise. Just hold the pad and turn it counter-clockwise. Watch out when you screw off the metal horn ring as the spring underneath will pop it out towards you and you don't want to scratch the steering wheel or any part of the interior as it goes flying back at you! So, hold tight onto the metal ring. Then, to install the horn ring back on, push down and find the holes on the steering wheel into which it locks, then turn it clock-wise until it fits back in.
