Using your finger nails as the plastic is very, very soft.
1. Very carefully lift the trim around the inside of gear shift up
2. Reach your fingers in at the bottom and lift. There are three or four (I can't remember which) tabs going up each side. Lift from the bottom of the horseshoe and work your way up each side.
3. Carefully lift the trim away from the console and flip over towards the passenger seat. Use a screwdriver to remove the two screws holding the traction control button to the trim.
See the thread linked in my sig to the Bluetooth AUX for more details.
