You should apply to renew your Advance Parole at least 120–150 days before it expires.

File Form I-131 to request a new travel document while your green card case is still pending.

If your Advance Parole expires, you should not travel until you get a new one — leaving without it can abandon your green card application.

USCIS often processes Advance Parole renewals together with EAD renewals if filed together.
