I like how the arm rest height can be adjusted. However I usually have to wiggle the arm rest up and down and 'hope' that it ends up being in the height that I want. Is there a special technique to set the arm rest height (I think there's 3 levels....low and flat, middle and high) without wiggling it up and down and hoping for the best? Around town I when I'm shifting gears a lot I like to have the arm rest down so it doesn't get in the way. Whereas motorway cruising I like to have it high.
