2017~2025 2025 PP CX-5 Cylinder Deactivation

[SurfDoggie]

Just bought a new 2025 this past saturday. Love the car, but it doesnt seem to me CDA is working. I had the CDA turned off by the sales rep for the test drive. Now that I have been driving a few days it has occured to me that it should be reactivating every time I restart the car? I have noted while at stops the Tack stays just under 1k which leads me to believe its not working as it should? Im new to the car and come from a 2017 GT that did not have CDA so I have no idea if this is something I should look into or if its fine. Personally not a fan of CDA and don't want to try and "Fix" it if its not broken?

Your sales rep was feeding you a line...CD cannot be turned off and on.

There is a screen in the infotainment system that has a graphic showing the 4 cylinders and which if any are deactivated.

I'm not sure about the exact distance, but CDA is not active during the first 100 km (65 mi) of a new CX-5.

You should not notice CDA in day-to-day driving. It's pretty damn seamless unless (maybe) you have a sixth sense about things mechanical. I didn't like the idea of my wife's '23 having it either, but I have to admit I never think about it in use.

Thanks for all the responses! I retested and it seems I am not pushing the break down far enough to activate it. DOH! So it is working as expected. Stickerbush mentioned there was no way to turn it off? The sales guy showed me a specific button on the lower left of the dash, by TCS on/off. I will have to check that out and see if I can in fact disable it per driving session.

My first car with CDA so I retested. I was not pushing the break peddle down far enough to activate CDA. Car only has 50 mi and CDA working as expected, user error

It sounds like you are talking about iStop, rather than Cylinder Deactivation. iStop has a button to disable and activates (stops the engine) when you come to a stop and press the brake firmly enough.

I think you hit the nail on the head. CD doesn't activate until you hit cruise speed and you cant deactivate it. You can deactivate I-Stop but you have to do it each time you start the car.

You are correct, I have confused the two. I was talking about iStop. Thank you! I guess it would be helpful if I actually asked the right questions.

Thanks, RedBarron pointed out that I was actually asking about i-Stop and confusing the two. I didnt think iStop was working as expected. Turns out the non-issue was user error. I was not depressing the brake far enough to activate it.
