Sorry...I am a novice currently. So you can have Auto Pilot on and LKA off and it will just act like in Adaptive cruise mode allowing for the car in front slowing or stopping and starting off again with a prod of the accelerator but you still need to steer the car and it will not recognize stop signs or traffic lights etc?
In other words it is virtually the same as Intelligent Adaptive Cruise Control on some ICE vehicles?
What does TJA supposed to do please?
TJA is traffic jam alert
In slow moving traffic it will follow the car in front and stop and go as required.
If it's been too long it prompts you to touch the accelerator to set off again after a stop.
TJA on the motorway manages the adaptive cruise control but also steers the car via the white lines.
Its quite basic but will steer you round gentle corners on the motorway, keeping you between the lines.
It does require some steering input from you every 20-30 seconds or it warns you to put your hands on the wheel.
A tiny bit of movement on the wheel keeps it going ok.
It is a weird feeling having the car steer for you.
It will also speed up and slow down with the car in front too.
It's basic autopilot and works ok.
Just be aware if you want to change lanes make sure you indicate first or it will try keep you in the lane.
And this is LKA lane keep assist turned off !
Horrible with that on as well.
Not for the faint hearted
