Add FSD to a Lexus CT Hybrid? Here's what works
Tesla's FSD stays on Teslas. But your CT Hybrid can steer itself and follow traffic with one device plugged in behind the mirror.
Yes. Your CT Hybrid is on comma's list.
comma lists the 2017–2018 CT Hybrid. It needs Lexus Safety System+ on the car. The car's own adaptive cruise keeps speed control. Steering works all the way down to a stop.
Steers itself in the lane
Continuous centring on highways and most roads, not a nudge back from the line.
Follows the car ahead
Your car's adaptive cruise keeps doing the gas and brakes while openpilot steers.
You stay in charge
A driver camera checks your eyes. No city turns, no naps, no FSD claims.
How to add it to your CT Hybrid
Four steps. No wiring cut, no dealer visit.
- 1
Confirm your year and trim
Open your exact CT Hybrid below. Trim names decide whether the car has the cruise and camera openpilot needs.
- 2
Order the comma four with the Toyota A connector
Pick your car in comma's shop and the right harness is added. Nothing else is required.
- 3
Mount it behind the mirror
Stick the mount high and centred, plug the harness in at the camera, and route one cable. About fifteen minutes.
- 4
Drive a few minutes, then engage
It calibrates on your first drive. Then press your cruise button and the CT Hybrid takes the lane.
What the first drive is like
Every CT Hybrid comma lists
Open your year for the exact trim, harness, and what controls speed.
Lexus Safety System+ versus openpilot
Lane Tracing Assist centres the lane with radar cruise on, hands on the wheel. openpilot adds the same on older Lexus models and works down to a stop.

Questions CT Hybrid owners ask
Is this Tesla FSD for a CT Hybrid?
No. FSD is Tesla software for Tesla cars. This is openpilot, an open-source driver-assist system that steers and follows traffic on your CT Hybrid. You watch the road and stay responsible.
Which Lexus CT Hybrid years work?
comma lists the 2017–2018 CT Hybrid, with Lexus Safety System+. Open the exact year below to confirm your trim.
Do I keep Lexus Safety System+?
Yes. The harness sits between the car and its camera, and your factory safety features keep working. Unplug it and the car is stock again.
Does it handle stop-and-go traffic?
It slows and stops behind traffic. On this CT Hybrid you tap resume to move off again.
Is there a subscription?
No. The device and the software are a one-time purchase. comma prime is an optional extra for remote access and longer drive storage.
Do I need to keep my hands on the wheel?
Not constantly. A small camera watches that your eyes stay on the road, and openpilot warns you and stops steering if they do not.
