Awesome, very detailed! Thank you very much.Ronzuki wrote:Either Or...the button on the dash will disable the AWD system's control to manipulate the rear differential's viscous coupler located at the differential's pinion. The AWD drivetrain is always rotating, AWD activated or not. To answer the question, depressing the button de-activates the AWD, therefore one may assume that the intention was to be in AWD mode at all times. I activate it in the bad weather... rain, snow, etc. and when I'm really enjoying myself driving like a maniac through the twisties. no harm no foul to leave it active all the time. It's an intelligent system and enables power to the rear differential as the plethora or computers see fit based on the situation. There is no noticeable improved fuel economy realized with it 'off' since the car is still lugging around the added 400lbs. of drivetrain gear, and as I'd stated, the masses are rotating constantly as long as the car is rolling.
