How noticable should it be when i adjust my lumbar support in my VRS? I have turned the knob all the way back and forth and honestly cant feel any difference. My car is only a couple of months old and it has been like this since i got it. If i had the time i would nip into the dealer but as it is it will probably just wait untill 1st service. Was just curious as ive had it in other cars and you could certainly feel the difference when adjusting it.

To be honest i havent read the manual but im assuming the dial above the back rest adjustment knob is the lumbar support knob as what else would it be?

There is nothing worse than playing with your knob with no end result.

Serioulsy though how does it work in others cars?

The manual isn't much help apart from pointing to the knob :( but..

You've found the correct knob, just don't rub it

Yep you should notice the difference when you adjust it but it doesn't move that quick.

Talking of the passenger seat IIRC turning the knob clockwise makes the lumbar more pronounced.

I'm guessing the drivers seat is the same?

Don't know as i haven't driven it yet.
