Get in the driver's seat and turn off the car and the radio. I usually listen to the radio for a few minutes before removing it during the process. 2. Pop open the ashtray lid and empty the ashtray. 3. Use either the plastic wedge or your fingers to grab ahold of the front of the shifter surround trim and gently pull it up. Unplug the connectors from it and remove the shifter knob with it. (set all of this in the passenger seat so you won't misplace anything).

With the ashtray open, grab ahold of the front of the other trim piece around the shifter that goes from the ashtray to the cupholder. Pop this trim piece off and set it aside. 5. Next open the cupholder area and reach down inside it with either the small screwdriver or some small but long hook and remove the rubber insert where you would set a second cup/drink. (Most people seem to use this as a trashcan or coin holder). The

There is a small tab on the cupholder that you need to pull slightly up on to pop it loose and then it just twists out and can be removed and set aside. After this, you will notice 2 small tabs at the front of this section that can be pried loose and you can fold the front half of the cupholder section back exposing (2) of the (4) 10mm screws/bolts you must remove.

Next, remove the lower cloth section mat at the bottom of this area and it will expose the remaining (2) 10mm bolts you must remove. *****Notice: if you have the rear A/C option, you will need to remove the covers for it and then unscrew the rear a/c blower using the T20 torx screwdriver. Next unplug it and set it aside and then remove the (2) exposed black 10mm bolts. (it is inside the center console; there are two small slots on the left and right front side of the top cover where a small flat screw driver was stuck in to release the latch)

Now you should see the black tab at the right rear of the shifter base. Press it forward and pull the gear selector back into neutral or drive. If you have not engaged the parking brake, do so NOW. Grab the small flat tip screwdriver and gently pry the two exposed tabs on the ashtray and pull the assembly up and out of the way. Also, don't forget to unplug it and then set it aside.
