Coles said the side's physicality needed to lift, and they would have to be better at the breakdown.
He said France might take something from Ireland's method to beat the All Blacks last week, but he felt their different style was more likely. They used the ball well and had good players who tried to run over opponents.
"We're expecting something a little bit different," he said.
"It's definitely a big Test, and for us to finish well we need to perform. We're hurting from Ireland, so there is plenty of motivation to perform well."
He and flanker Sam Cane would try to bring experience and leadership to the effort and help drive the team, he said.
"We've been taking notice of this French team, the way they've been playing in the Six Nations, and getting a couple of good wins against Argentina and Georgia. It just seems they are playing with a lot of belief, and a lot of freedom, that I haven't seen in a while.
"I think they're a lot more consistent than in 2018, the last time we came over. And they have that French flair we love to see.
"They're in a good position, and even the team they sent over to Aussie [in July], they pushed them to game three. That wasn't their strongest team, but they had a lot of guys that stepped up, and they've created a lot of depth in that team. They're a team on the rise.
"It would be a great scalp to get, but we're under no illusions about how tough and how physical this Test is going to be," he said.
Fullback Jordie Barrett said halfback Antoine Dupont would be a player to watch. He dictated a lot of their play. Stifling what he wanted to do would help the All Blacks go a long way towards winning the game. And his combination with first five-eighths Romain Ntamack would also be important.
He said the All Blacks would be looking to get more ball than they had against Ireland. Achieving that would then involve less tackling.
They would also be looking to deny the French the chance to play on their emotions and to benefit from the lift they take from their home crowd.
"They're a proud country and that means a lot to them so, hopefully, we can stifle that," he said.
Northern hemisphere teams liked to squeeze the life out of opponents, so it was important when having the ball to cherish it, he said.
"With any French team you never really know what to expect. Hopefully we've done our homework of what we are expecting."
One of the harder-worked team members with high minutes on tour, Barrett said he relished the opportunities, even the extra responsibility of goal-kicking.
"It helps build continuity from week-to-week playing big Tests against quality opposition. It helps you grow your game and you learn things you can take into next week too," he said.
