How It Works

It's Simple.

The AAC device is designed for straightforward installation and effortless operation

Effortless installation

Installed cleanly behind your dashboard. No cutting or coding. On most Toyota models, it can be installed at home with basic tools and light technical understanding. For models with a more premium interior design, we recommend letting your trusted garage handle the install. Fully reversible and hassle-free.

Step 1

Set your preferences

Use the built-in micro-switches to decide which systems (ISA, LKA, PCS) you want AAC to control. Once set, the configuration stays stored.

Step 2

Press the cancel-button

With AAC installed and configured, just press the steering wheel’s cancel-button. In about 1 second, your preferences are applied — no menus, no hassle.

Step 3

Just drive

No flashing. No distractions. No tech frustration. Just peace of mind and that raw, mechanical feeling back in your hands.

Step 4

🏁 GR Yaris Bonus Feature

Thanks to its manual handbrake, the GR Yaris benefits from an exclusive bonus feature: The warning message and beeping sound when driving with the handbrake engaged are automatically delayed by 5 seconds. Ideal for controlled drifts and spirited driving, which the GR Yaris was built for.

Frequently Asked Questions

Can I get in trouble for using AAC?
No. Since all the systems get reset every time you start your car, AAC stays within legal limits for road use.
Will it work on my car?
👉 Check the model list to see if your vehicle is available.

If it’s not yet supported, you can sign up for email updates and we’ll notify you as soon as it’s ready for your car.
Can I turn everything back on?
Absolutely. Press the Cancel Button again for 3 seconds and the systems will activate again.
What if I change my mind?
No problem. AAC is easy to remove, fully reversible, and backed by a 30-day satisfaction guarantee.
Will my warranty be safe?
The AAC module is technically safe and used at your own responsibility.
It is fully plug & play, does not modify any wiring, does not interfere with control units, and is undetectable through vehicle diagnostics. It is virtually impossible for the module to cause any damage.

⚠️ Toyota is legally required to exclude warranty coverage for damage caused by third-party accessories.

👉 However, the AAC module is specifically designed to be completely safe for your vehicle. It is fully reversible and does not alter or disable any safety-relevant systems.
Does the module also work on right-hand drive vehicles?
The module has so far only been tested on left-hand drive vehicles. If you drive a right-hand drive model and are interested in testing it, feel free to reach out to us via the contact form.
