To disable auto start stop in a Toyota Supra, press the start/stop off button (if your model has one) each time you start the car, since the setting usually resets at the next start. Permanent options, such as coding tools or plug-in eliminator devices, change how the car’s electronics work and can affect warranty coverage or trigger warnings, so check with a dealer or specialist before using one. Check the owner’s manual for your model year.
Understanding the Auto Start/Stop Feature in Your Supra
Auto start/stop switches the engine off when the car stops, for example at a light, and restarts it when you release the brake. It saves fuel and reduces emissions in traffic. Whether your car has it and how it behaves depend on the model year.
Why You Might Want to Disable the Auto Start/Stop Feature?
- You dislike the restarts in traffic.
- You want the engine running for air conditioning.
- You want the engine to stay warm.
- You prefer smoother stop and go.
How to Temporarily Disable Auto Start Stop in a Toyota Supra
The simplest option is a button on the console or dash that switches the system off for that drive.
Manual Button Activation
- Start the car.
- Find the start/stop off button; see the manual for its location.
- Press it and look for the indicator on the dash.
- Repeat each time you start the car, since it usually resets.
Driving Mode Adjustments
Some drive modes change how the system behaves. Check the manual to see how yours works.
Choosing the Right OBD2 Device to Disable the Auto Start/Stop Feature
Plug-in devices that store the off setting exist, but they change how the car’s computer behaves. Check the claims, the compatibility and the warranty position before you buy.
Adapter Compatibility Considerations
Only use a device that says it supports your exact model year and engine. Poor devices can cause faults.
Recommended OBD2 Devices
We do not recommend a specific device. Ask a dealer or a specialist about your options and the risks.
How to Permanently Disable the Auto Start/Stop Feature?
A permanent change needs coding or a device that alters the system. Both change the car’s electronics, so they carry risk, and Toyota may not support them.

Follow the manufacturer’s instructions for the specific device. Disconnecting parts or plugging in devices can cause warning lights, so take care or have a specialist fit it.

Some owners use coding apps that were made for BMW platforms to change settings. This is not an approved Toyota method, and wrong changes can cause faults. Only attempt it if you understand the risks, and keep a record of the original settings.
Common Problems When Disabling Auto Start/Stop?
Problems with add-on devices and coding include warning lights and compatibility issues.
Compatibility Issues With Devices
