I brought my TLX home last night, black copper pearl with espresso interior, i4 with tech package. I am so pleased with the car. The drive home was about 60 miles, no problems. I thought I had the Lane Keeping Assist turned on but it never flashed and I didn't have time to mess with it while driving the freeway at night. This morning on the way to work I got several alerts on the right side of the car while driving inside the lane. Moving to the right or left of my lane and over to the lane marker did not trigger any alert, only sporadic warnings while in my lane. When I got to work I looked up the LKAS instructions as to how to turn it on which requires hitting Main first and then pressing the button. So I don't believe I have it even turned on. I am going to test it out this weekend but wondering if anyone else has seen this?
Without
LKAS turned on you still should get alerts when you leave the lane only. Mine beeps and flashes when I leave a lane or come close to leaving the lane.
When you go into
Main and select the
LKAS button on the lower right part of the steering when, you should notice that the lane markers appear but the boxes that make up the lane markers are empty or black on the display. There should also be a steering wheel pictured with hands on it. With KLAS fully turned on, the lane markers become filled in with white. This indicated that LKAS has a lock on the lane markers. When this happens, you can feel the steering wheel tug back and forth. If it is locked on, let go of the steering wheel and it should steer itself for 15 seconds and then ask for you to take over.
When I first got the car, I thought
LKAS was turned on. It was not.
LKAS turns off automatically when you power down. Also,
LKAS disengages when you switch lanes, stop, go too slow or it loses track of the road. I have been on a road that the lines are dirty and the contrast between the stripes and road were not contrasted enough and the lock on would break.
It is amazing that
LKAS actually steers around turnpike or wide highway turns. It's feels scary to let go at first.
