Sorry to bring up an old thread. I have a friend who works at Toyota, that agreed to plug the scan tool into my car and make adjustments to things like auto lock, light delay etc. I located the service manual showing the adjustment settings. I find that when it's dusk and the sun it setting, my auto headlights don't turn on. If I block the sensor for a second or two, then take my hand off, the lights stay on. So my question is, on the service manual the Sensitivity option can be adjusted to; Light 2 / Light 1 / Normal / Dark 1 / Dark 2 Which way do I need to go to make my headlights turn on sooner (with it's still a little light outside) Thanks in advance!
