Hi all,

I'm new here and looking for answers to some issues. I searched here but, surprisingly, haven't found anything about my issue. I want to just use my cruise control in it's basic configuration without the radar features. I have a 2023 CX-5 Carbon having the MRCC with Stop & Go. I know that, while the car is running and the MRCC is on, I can deactivate the MRCC by holding down the MODE button for about 3 seconds. But it resest back to MRCC each time the car is re-started. Is there a way to permanently deactivate it?

Edit: After seeing some responses I need to clarify. I'm not interested in a hack or illegimate bypass or alteration to achieve this. I'm hoping that there's either a user selectable method, perhaps unadvertised, or that Mazda techs can achieve this via some way that's authorized by Mazda.

Update: If you're also interested in knowing the answer to this, I'll save you from reading all the below banter, much of it irrelevant to the question, and tell you that the answer is "no".

 

Can't you just set the distance to zero?

 

Unfortunately no. But even if I could there are other features of the MRCC that would still be active, such as it applying the brakes if the car goes any faster than the set speed, like when going downhill.

 

Mazda still under WARRATY and deactivating any system or feature that is not outlined in the owner's manual (only) can void some warranty coverage of systems and parts.
Cruise control on newer Mazda from about 2000 to present (model year dependent VIN needed) when active is considered in the operations of safety system and as such there also may be state and Federal violation tampering , altering or adjusting outside normal and outlined (owners manual) with those systems.

My recommendation is to talk to your Mazda dealer service dept or contact Mazda USA direct.

Appreciate your concern. I've done that and have received conflicting answers or guesses. None of the answers were that it was possible. Few seem to really understand how all works with these tech laden cars, and I've received more bad info than good from Mazda to the point where I don't trust any of it. Looking to see what people here have found.

Case in point, I took the CX-5 in for service last week for routine service plus some issues. One was that the remote no longer transmitted to the car (not a battery issue). I received the car back with all the routine service done, but regarding the remote the response was the common refrain "couldn't duplicate the problem". But lo and behold all of a sudden the remote worked. Later I noticed a new problem in that when I use that remote to unlock the car the seat moves up an inch. I went back and a service tech checked it out. He had no idea what the issue was and couldn't fix it, so I have to schedule a service for that. Said he'd never seen that before. The next day I went back to test drive a loaner CX-30 they were selling. Both of the remotes had the exact issue that mine had when I first brought my CX-5 in for service (the issue that couldn't be duplicated). They replaced a battery and nothing. Two techs couldn't figure it out and again said they'd never seen anything like it before. I was asked to come back another day.

 

I suspect there is a way (by reprogramming modules AS-BUILT configuration), BUT. 1) It's safety issue (as mentioned above) 2) this reprogramming likely to cause problems in other modules. 3) Why? just - why? Without cars in front of you MRCC acts as simple cruise control. With cars in front of you, if you don't trust radar, you'll deactivate CC anyway.

I'd suggest avoiding this service in the future. This is mazda seat memory saved to the key. You can save your seat settings to key by pressing "set" button and then (within 5 sec) "unlock" button on the key.
This is in the manual.

 

This is correct , however you need access to the BCM , SRS , ABS, and I believe one or more other program files to do this correctly. It is not for a DIY, or anyone not having the full access to the programming and knowledge and experience in changing these configuration in those programs . And some only Mazda has the access to even entering these files. I am not aware of any company that broke the codes to go into global settings outside of Mazda.

Besides very few even “tooners” would like not wait to do this of they did have a program to access the files and not one true ECU/EFI Performance Calabrator that I know of would even want to unless it was a legitimate track only vehicle .

Not sure why you would even mention this in the first place?

 

Not being a jerk here, and I know it doesn't help you now.
But if certain safety features are not wanted by the purchaser, it would be pertinent that the purchaser evaluate the safety features and their functions of said vehicle, before purchasing.
That said: With regards to all safety features on anything.
They are there for a reason and should never be disabled/tampered with.
Disabling/tampering with any safety features is against the law in most states/countries and will certainly make you libel (criminally charged including jail time) for any issues that should arise from doing so.
Like property damage and/or injuries to yourself or others.
The majority of insurance companies will reduce payments or not pay at all if you have tampered, disabled or refused to use required safety features.
In addition, they can raise your insurance rates and/or refuse to insure you at all.

 

I see. So when I push the MODE button to deactivate the MRCC this is tampering? Or unlawfully disabling of a safety feature? No, it's actually a feature that's explained in the manual. I just want to know if there's a way to turn it off once instead of having to do it every time the car is started. And in a way that Mazda has designed into the car to be set by an owner or a tech. I'm not interested in any hacks.

Regarding not ordering a feature to begin with - really? Gee, why didn't I think of that! Don't you know that it doesn't work that way? Eg, have you tried buying a car with navigation that didn't also come air conditioning? Just so you know when you go to buy your first car, you cannot pick and choose each option you want.

And Institor, if I didn't know better I'd think you were joking. You mean a car with seat memory can actually memorize the position of the seat? What a revelation, thank you so much! I'll have to let the Mazda service techs in on that. Don't worry, I'll give you the credit for discovering this feature. Unfortunately that's not the problem. Would've been nice though.

It seems that the answer to my original question is "no".

 

As I stated in my initial post, it's because I want to. I actually enjoy driving cars. And I mean "driving" it, not just sitting behind the wheel as a passenger. There are some features that I like, like basic cruise control. It's nice on the highway, especially on long drives, to maintain a set speed and give my foot a break. But in most other conditions I prefer to drive the car. There are many people like this. Have you ever gone on a performance enthusiast car site and asked them why they might prefer driving a stick? If you have to ask "why" then you'll just never understand. I'm going to guess that's something you wouldn't want to do yourself. I understand there are people who are annoyed by the "task" of driving and would rather everything was automated. Then they could play on their PED instead. I'm not one of those.

After over 50 years of driving and close to a million miles, I can say that I've never caused an accident. And that I've prevented hundreds by defensive driving, and in 1 case even by grabbing the steering wheel, from the passenger seat, and averting one. For me, disabling the MRCC isn't a safety issue. It sounds like it may be for you.
