[Tools Required]
Small flat head screw driver
A cloth (any will do)
Step 1. take small flat head and place cloth over the tip.
Step 2. place tip of screw driver just above the chrome base of the shifter knob
Step 3. pry a bit gently but with a little force (not enough to break it)
Step 4. the cap should pop off then all thats required is just pull the shifter knob up.
Note. i read that its easier to do this with the vehicle in neutral rather then park as then the shifter is facing almost 90 degrees straight up.
Hope this helps
