New gx owner
New Lexus owner. I just got a 22 GX and wanted to ask if I should run the car under 4LO mode (Four wheel drive low) a few times a year to help the 4LO system staying "healthy", since I'm not really planning to do any offroading anytime soon. That might be a silly question, but I would appreciate any kind of advice on that. It's my first luxury car, so I want to make sure I maintain it properly. Thanks!

Not only does the 4hi/lo need cycling but the center diff lock does also. This should be done at least twice for year, better is 3-4 times per year. Non use of those costly solenoids is far more likely to cause problems than cycling them, which they are designed to do. Don't forget to cycle other electric goodies like the sunroof, power windows and seats, mirrors etc. a few times per year also.

I find an empty parking lot and do this. Don't turn the wheels on pavement when the center diff is locked. Here are the different settings I test drive in a parking lot:
1. 4 LO
2. 4 LO with center diff locked
3. 4 HI with center diff locked
Unlock center diff and back to normal driving.
