sunroof acting strange, opens but after some unusual button, tilt does not work

car : 2014 ML350 4Matic

the sun roof started acting strange i think after battery replacement. It opens but does not open with one touch normally, one has to push the button up, down (like tilting) and them press backward to start the opening process. closing is working normally
Tilt partition stopped working completely, cannot make it tolt with any combination of button forward backward or upward/downward push.

same issue (different form) happened few times before during warranty and dealer did something or replace the module/motor there to get it fixed but now it came back

it appears system is out of sync or something...is there a procedure which i can follow to reprogram the sunroof system?

The owner's manual has a reset procedure in it.

would you mind pointing out which page (or under which section) in the manual describes that procedure.? The reason i am asking is i do have the original 2014 ML350 user manual that came with car and the page where is describe sun roof (the manual dont have any index which is odd) does not talk about anything reprogramming

Thanks!
