MX with 6 seats. Last night, i got the warning on my display that one of the middle row seat is not locked or not at proper position as my kids were adjusting it for suitable legroom. It happened twice. Every time we moved seat forward and reversed a bit and then it was ok. Are there certain locking positions? I was concerned that when car is moving fast, are we suppose to keep the seat at certain position or wherever its comfortable so why such warning?
