omar302 Posted December 3, 2014 Report Share Posted December 3, 2014 I just read in the owners manual the following regarding BLIS: Day and night brightnessThe BLIS and/or CTA alert will automatically dim when the headlampswitch is in PARK, ON, or AUTO ON and night time darkness has beendetected by the sun sensor. I have never noticed this before, and now after testing, I am sure that alert LED brightness does NOT change, it is always dim (hard to see during the day). Tested this by turning the Park/Headlights on and off while the BLIS was working, even when the instrument panel lights were dimming/brightening, the BLIS led brightness remained the same. Can anyone confirm if theirs dim or not? Quote Link to comment Share on other sites More sharing options...
ls973800 Posted December 3, 2014 Report Share Posted December 3, 2014 The BLIS indicators in the outside mirrors are never hard to see on mine during the day or night. They are not too bright at night that I have ever noticed. Daytime has never been too dim. Even though you are switching the light switch and the instrument panel dims, the manual says the sun sensor has to detect darkness. Have you tried covering the sensor when you do the manual headlight switch maneuvering? Quote Link to comment Share on other sites More sharing options...
omar302 Posted December 3, 2014 Author Report Share Posted December 3, 2014 Yes. Tried covering the light sensor until the auto lights came on & instrument panel lights dimmed. Guess it's one more thing to add to my list for the dealer. Quote Link to comment Share on other sites More sharing options...
