A couple of other issues

[97 Continental]

I just thought of a couple other minor issues. Is there a way to reset sensors in the low tire pressure system? I'm getting a low air warning, however tire pressure is good. Also, what's with the driver's door armrest tearing? Mine is torn, and I've looked at others for sale, etc. that are torn in the same area. Was this a common problem for this era Conti? Don't get me wrong, I still love my car, just curious though.

Thanks!
