Bought a 2020 Suzuki Swift that has the auto stop feature that I find a bit annoying. I know it can be overidden with a button in the car, but that has to be pressed every time the car is started. Looking for a more permanent solution.

I have a 2016 Fortuner and have not figured out how to disable it. Toyota said no-can-do.

I should try again though, it's been a while.

The most reliable, permanent, and non-destructive solution to disable the auto start-stop feature on your 2020 Suzuki Swift is to install an aftermarket plug-and-play memory bypass cable.

Because auto start-stop functions are tied directly to vehicle emissions and fuel economy certifications, auto manufacturers are legally prohibited from providing a permanent "off" switch in the factory infotainment or dashboard menus.

The primary permanent solutions are detailed below, ranging from the cleanest professional method to free mechanical workarounds.

1. The Best Solution: Plug-and-Play Bypass Cable

This is a dedicated micro-relay device that plugs directly behind your factory "A-OFF" button. It tricks the car into thinking you pressed the button 3 to 6 seconds after every engine start.

• How it works: It acts as an automatic finger. When you start the car, the default state becomes "Disabled". If you ever want to turn the system back on, you simply press the original dashboard button like normal.

• Installation: You use a plastic trim tool to pop open the lower dashboard panel to the right or left of your steering wheel, disconnect the factory wire harness from the auto-stop button, snap this bypass cable inline between them, and click the panel back together. No wires are sliced, and it will not drain your battery.

• Where to find it: You can find these online by searching for a "Suzuki Swift A2L 2017-2023 Auto Start Stop Eliminator" or "Canceller" on platforms like AliExpress or Lazada for roughly $15 to $25.

2. The Free "Hack": The Zip-Tie / Jamming Method

If you do not want to spend money, you can choose to physically jam the dashboard button into a permanently depressed state.

• How it works: On the 2020 Swift, the factory button uses a standard mechanical closing circuit. If you use a thin tool to fully depress the button and wedge a tiny sliver of plastic, thick paper, or a skinny zip-tie head into the gaps surrounding the button, it will stay permanently pushed in.

• The Downside: While free, this look can be unsightly. Over time, leaving the mechanical switch permanently compressed can occasionally cause the car’s Body Control Module (BCM) to throw an error code because it registers a "stuck switch" signal upon ignition.

3. The ECU Coding Method

The system can be programmed out entirely using digital modification tools.

• How it works: A local car tuning or diagnostics shop can plug a bi-directional OBD2 computer scanning tool into your vehicle's diagnostic port. They can adjust the parameters of your battery voltage threshold. By raising the minimum voltage requirement for the auto-stop feature to operate (e.g., setting it to 13V), the car will constantly assume the battery does not have enough juice to safely shut down, disabling the system permanently without dashboard lights.

• The Downside: Dealerships will generally not do this for you. Furthermore, a factory software update during routine servicing might flash the ECU back to standard settings, wiping out your custom configuration.

• There are YouTube videos to assist I believe.

I have a Toyota Hilux Revo Rocco 2.8 4x4 my 2020, before minor changes later that year. I bought it new and after a couple months I was tired of this auto stop function. I bought a plug and play cable online, watched a YT video to learn how dismantle dashboard. It was very easy and took only 20-30 minutes. Dashboard work took almost all time.

I saw someone found a similar cable for your Suzuki. Buy it. Good luck!

I hired a new Vauxall Corsa for three days in the UK that also had this feature. Very annoying. Ony way I could get around it was to keep a few revs up or depress the clutch.

There was another feature that I considered dangerous. The steering strongly resisted you moving out of your lane unless you first used the appropriate turn signal. When a pothole suddenly appeared in my lane I found swerving to avoid it was resisted because I hadn't signaled my intention.

Saw a clip on Instagram. Apparently there's a small thingie connected to the plus side of the car battery. You have to disconnect it and that's it...

If I could eliminate a problem with a single press of a button, I'd press the button.

8 years ago I hired a Mercedes SUV in the UK. I was driving it for almost a week before I realised it had automatic engine stop, and that because I noticed the Rev counter was on zero at a set of traffic lights. There were a number of things which were automatic, although there were 2 occasions I was glad to be in control. One, an idiot 'blonde' turned right against a no entry sign. The other nutter must have been three sheet to the wind, when he pulled out of the pub car park without looking. They are not only in Thailand!

I drove a rental in the US with the run-stop, but it did not really bother me as it was a gas-burner. The diesel auto-stop-start is much more noticeable and much more annoying.

It has to be very hard on the battery.

Pushing the button to turn it off is annoying, because I often do not remember until it shuts off.

I saw a YT video that showed putting a thin piece of plastic on the side of the button to hold it down. You first have to make sure it's on the setting you want--auto on or off, then hold the button down and slide the plastic in the side to hold the button in. Haven't tried it yet but will soon. I hate the auto start stop feature; many people think it's to save fuel, but it's only for emmisions it doesn't save that much fuel.

Let me know how it works out.

YouTube will tell you, it worked for my Mazda.

What a dumb stupid function. Child runs into the road instinct says brake, steer around child. Not indicate first, of course checking the rear view mirror, then execute evasive manoeuvre.
