When it is a head restraint! Any fool should know that, but apparently I am not just any fool.
I was asking my Volt Adviser how to get my rear seat headrests off for those times when I might want to fold down the rear seat backs for extra cargo space. I could not get them to come off and we keep the front seats so far back that the rear seats won't fold down. Since I normally want to be able to carry two people in back, I don't want to leave the headrests off all the time, but want to be able to pop them off quickly as necessary. I tried using the search feature of my PDF owner's manual, but got nowhere. That's because I was too braindead to think of alternative names for those little things. My Volt Adviser was patient and walked me through it, and I now can do this little chore on my own without any help. I even went back to the owner's manual and found the information I knew had to be there. All you have to do is look for Head Restraint Removal and Reinstallation. Key part being "Head Restraint", not "headrest" or "head rest". D'oh!
Here's what it looks like in the manual:
And here's a photo of my car that makes it even clearer:
You can see a secret button on the left side that needs to be depressed the same way as the easily visible button on the right in order for the "head restraint" to pop off. Easy when you know how.
While out there taking pix for this, thought I would mention the cargo net accessory. I don't like where GM thinks it should go because it gets in my way. I have moved it to the front of the cargo bay, farthest away from the hatch. It isn't really designed to go here, but works just fine this way. I latch the side clips to the seat back to keep it from swaying.
Yes, I have the seat barrier and the window shade accessories too, all included in the car's invoice. I don't think I would have paid GM's prices for them if they had not already been on the sticker, but they are very useful.
