The BLIS never asked me for length of my Trailer, just asked if my trailer was wider than 8 feet. I clicked yes, and that was it. I am not sure it works properly. Can anyone advise me if I am doing that right?
For BLIS to work while towing the trailer must be less than 8.2 feet wide (per manual). If you told it your trailer was wider, it automatically turns BLIS off while towing. The BLIS sensors can't see around a trailer wider than that.

I believe you are exceeding the limit for BLIS to work with a trailer. If you tell it that the trailer is within the limit, then you should be able to enter the length.

Remember Bliss is blind spot indicator system. Not oh hey the person is behind me far enough I can get over safely enough system. Don't ever get that confused between each other
I understand that, but in a previous thread someone stated it asked how long the trailer is. Mine did not give me that option.

It doesn't ask the length specifically. There is a setting for it. I believe there are three options, IIRC. I'm not around my truck so cannot verify. You can store 2 or 3 different trailer settings and chose as needed. It should be in the manual, or I'll get pictures next week for you, when I have my truck with me.

Again if you tell it the trailer is too wide it will not ask you for a trailer length. It simply disables BLIS with a trailer is connected.

Yes, there are settings for up to three different trailers, A-B-C. Set A to the trailer you use the most, then just go into settings and chose the other selection when towing a different trailer.

I use the clamp on mirrors shown previously and had the same issue with trucks passing on a two lane and the mirror head folding into the window. Almost lost my mirror too. Solved the problem my making a small clip that hooks the bottom edge of the stock mirror and use a small bungie cord from the clip up to the clamp on ones. Works perfect at holding the mirror on if a truck goes by. If the mirror head does fold in (drivers side only, never had the pass. one do it) I just open the window and push it back out. No big deal. As for BLIS, I have mine set for a 25 ft trailer, (TT trailer is 8 ft wide and 25 ft long) and I am very impressed with how it works. As a 40 year truck driver, I do not use it to judge if a car is there, that is what mirrors are for BUT it does alert me if a car is beside me on either side every time, even if they are near the rear of the trailer. Very impressive.

Don't mind my asking but what trailer are you towing that's wider than 8 ft? If I recall correctly that's getting into wide load territory in most states.

I tried clicking no, so I clicked yes and it stool didn’t work so I was experimenting. My trailer is 8’ so I tried both with no change. Sorry, didn’t state that correctly in post.

Speaking for myself, my snowmobile trailer is 8.5 ft wide. Making my BLIS not work and a challenge to see without tow mirrors. I bought some cheap clamp on mirrors but didn’t like them at all.

To set the trailer length in the menu, go to Driver Assist > Blind Spot. From there, select "Trailer lengths" to enter the length (for up to three trailers), then "Trailer" to select the appropriate one.
