Asked for a response to McIlroy's comments, Montgomerie insisted that the contest "is not an exhibition and it never will be" but added that he would not get drawn into any war-of-words with the 20-year-old over the issue.
"It's a very unique, special event and much more nerve-wracking than a major," said the 45-year-old Scot.
"When you play in it you want to be there again and again."
"(But) Please don't say that Monty and Rory are having a war here. I haven't said that.
"Rory will understand when - and it's not an 'if' - he is a Ryder Cup player.
"He'll understand the pressures involved and the whole scenario of the Ryder Cup will hit him very hard.
"If he's qualified or necessitates a pick I would definitely speak to every player as to what to expect."
Despite his views at this stage McIlroy still expects to "relish every moment of it" should he play and adds: "Obviously I'll try my best for the team - but I'm not going to go running around fist-pumping."
Montgomerie declared himself perfectly happy with the decision by the players' committee on Tuesday night to grant him a third wild card.
Opposite number Corey Pavin will have one more than that, but Montgomerie said:"I got what I wanted. I'm just concerned about getting the strongest team and having one more option might just allow me to do that."
