At startup today I got a series of short beeps....like when you are too close to an object when in reverse. I ignored it as I knew nothing was behind me. And then later in the day I got the "Parking Assist off" in the DIC. I cleaned the snow away and still it showed "OFF". I was unable to select "ON" using the check mark/reset ???. I was convinced I would need to bring it in for servicing but sometime later that same trip after another startup "Parking Assist" was back "on" ???.
