Hello everyone, new member here as of today. Purchased a used 2007 LS460 and collected it yesterday from Lexus Carlisle. Very impressed after 4 months searching for one.
On the way home I was getting familiar with the toys such as LKA, Cruise with the distance controlled function etc.
After trying to absorb as much technical info as possible when I got home from the manuals I didn't find any real detailed info as to how the driver monitor system worked other than the basic knowledge that the small box on the steering column cowl tracks the position of the driver's head/face position. There were no visible LED's lit up in the box while driving and I wasn't keen on looking away from the road to see what happens.
Are there any function checks or other means of knowing if this device is doing what it is designed to do during actual driving.
Any comments would be welcome.
