Just checked and yes it will start, this is done encase the battery dies in the key fob wile you are in say the fast lane,
it does do a fair amount of bleeping as you walk away to give warning.

Seem to recall the X-ADV restarts if turned off on the kill switch & no fob??? (sure somebody with one will correct me)

but also several postings about it screwing the computer memory on the DCT box so having to reset it if kill switch used and left in drive
