Another Aduana Question-Expired TIP

[Solo]

I entered Mexico with an FMT and my vehicle a few years ago.

Since then I have switched to an FM3, which has always been current. I was under the impression that if my FM3 was current, my vehicle was ok.

I am leaving Mexico in a couple of weeks by car, and my "TIP" (temporary import permit) is very expired.

I am not bringing the car back to Mexico and plan on properly cancelling "TIP" etc. at the border

After reading a lot online I am unclear on if this will be a problem since my TIP is expired.

My question is, does anyone know if I will need a 'RETORNO SEGURO' "Safe Return" document issued by the Aduana? Or am I cool since my FM3 is current and I am not a permanent Residente Temporal?

I'd appreciate any info.
