Does my 2025 CX-5 Have Cylinder Deactivation?

[kymasabe@ya]

Just bought my '25 CX-5 S Select and never considered whether it had cylinder deactivation or not.
FYI, mine doesn't seem to have the auto start/stop thing, or i-stop or whatever it's called so hopefully cylinder deactivation is missing too.
How can I tell? Would it be listed on the window sticker?

Cylinder deactivation applies to the NA cars, while i-Stop applies to the turbos.

Not sure I-Stop is on the US turbos. I thought that was more a non-US option.

If memory serves, isn't there a screen you can go to in the info system that shows the cylinder deactivation process in real time? Find that screen and you should be able to see whether you have it or not.

VIN is easy to get but how would one go about getting engine and transmission numbers on a prospective purchase? And once you have these numbers how would they be used to determine whether or not the car has cylinder deactivation?

From TSB No.: 01-003/24 Check Engibe Light On with DTC P0524 or P055F:

NOTE: To identify vehicles with cylinder deactivation, examine the 8th digit of the VIN.
• L: 2.5L without cylinder deactivation
• M: 2.5L with cylinder deactivation

Thank you, the L or M information was very helpful !!

All 2025 CX5s with the 2.5L NA have it

This is incorrect.

It's on my turbo (US).

How do you know its a 2025 MY ?? Build date?

because the OP said "Just bought my '25 CX-5 S Select"

 

[dunhillmc]

This is incorrect.

which non-turbos don't have it?

 

[wlong01]

It's on my turbo (US).

What turbo? Your badge shows 2014 and 2019 Tourings.

yup it is on the cx50 but not on the cx5 I have a 2023 cx5 tubo and my neighbor a cx50 turbo.

Ok, that's clears it up. When Redbaron said it was on his turbo you have to assume he's talking about a CX-5 since we're in the CX-5 forum.
Hopefully I-Stop doesn't show up on the domestic CX-5's.

But here in the 2024 CX-5 manual it says it does... https://www.mazdausa.com/static/man...ped.?msockid=0513f47a5c9461ec2e72e7075ddb60dc

Only early production 2024s had istop and cylinder deactivation. The majority of 2024s don't because of parts shortages at the time

Still unclear. Does the new turbo CX-5's have I-Stop? Seems all of the references are to Cylinder deactivation and I-Stop. I know the turbos don't have CD but what about IStop.

It seems that some later model CX-5's have i-Stop and some don't. The only way to tell for sure is to go to your dealer and look at the buttons on the dash below and to the left of the steering wheel. If you see an "i-Stop OFF" button there, then it does.
