Kohli leads India into the fourth Test against Australia in Sydney starting Tuesday after MS Dhoni's shock retirement following the drawn match in Melbourne.
Asked on Monday if his confrontational style would change as captain, Kohli said he would urge his team to maintain a positive and aggressive attitude.
"It's important for the players to know that we need to be in a positive frame of mind," he told a media conference.
"A line doesn't need to be crossed but we're not here to back down from any sort of confrontation or any sort of battle so you will still see positive cricket and the same aggressive intent."
Kohli has been the most belligerent of the Indians throughout the series, which his team trail 2-0.
Asked about bowlers giving send-offs as has been the case at times during the series, Kohli agreed with Australia batsman David Warner and said it was unnecessary.
"That's basically a very unnecessary part of cricket because when you've got someone out you don't need to run towards them and saying anything " so I agree on that," he said.
"Collectively as a team you can celebrate and make a noise as much as you want but someone approaching the batsman out of his way and then coming back to the pack, I think that looks really bad on the field."
