I just bought a GS350 with the AFS system, nav and ML. I upgraded from a ES350. My question is do the AFS lights on GS turn as much as on the ES. I could tell when the ES lights turn, but have not yet seen the lights on the GS turn.

 

The AFS system does turn on GS!

 

they do turn, but they are more speed sensitive than both the ES and the RX.
In the RX, and ES, and I know this from exp. When I drop my car off these are the loaners I get and I mess with them to see what it does and doesn't have... With the RX and ES, they turn at full swing with just a slight turn in the wheel, the GS is more speed sensitive to the degree of angle as well as how much of the wheel you are turning. But, they do turn. You will be able to notice the driver's light more than the pass, b/c the pass, turn at less of a degree for obvious reasons. But yes ther both do turn when the AFS is set to "on".
