I have a 2017 RX 350 and I'd like to change the lane-change number of blinkers. The manual doesn't show me how and what I've seen on U-Tube doesn't work, maybe only works for US models only.
Have any of you done this on a 2017? or is this something only the dealer can do?
Thanks for any advice

This is a dealer customization option. When you bring it in for your first complimentary service, they provide you with a list of dealer customization options that you wish to change.
I made 2 changes:
- Lane change blinkers to 5
- Press and hold the door open button on the remote to lower all windows and open the roof.

Thanks MrQ, I've already taken her in for the 1st service and told them that nothing needed changing, but now I think this need addressing so I'll do it the next time I'm in.
