What does the ASR function do for you? I'm not an expert, I'm asking.
The ASR function does a couple of things. Mainly broken down into 2 categories:
Traction control:
This keeps your tires from spinning faster then the vehicle is going. As a result it can prevent fish tailing and improve overall acceleration on slippery surfaces. This is meant to function on asphalt (probably wont spin tires), wet asphalt, snow, ice, mud, wet grass, etc. The way this functions is in two ways, it brakes the individual wheel that is spinning (hence the open diff) and also limit the engine torque output. So when you start spinning tires you will notice that your engine will lower its RPMs and it almost seems like your throttle isn't working like normal, this prevents you from increasing the torque sent to the wheel which will just be fought by the brakes that are trying to prevent the spinning. You will also probably hear the ABS pump running to build brake pressure at the rear tires in this situation.
Stability control:
This feature is used to prevent the vehicle from sliding out of control if you take a corner too fast or have to make an emergency lane change (see Moose Test). This mainly just applies the brakes to stabilize the vehicle when it is sliding out of control of the driver.
My biggest complaint is how intrusive the Traction control is and is too strong in my opinion. One night this winter I was driving through a busy intersection and it was a little icy, I had good momentum off the light and was going probably 15-20 mph and I hit an icy patch causing one of the wheels to spin. The TC came in so strong that it brake the vehicle to a stand still and left me in the center of the intersection. I immediately hit the ASR button to start moving again and this allowed me to get some wheel spin and start moving but then locked down again. I have been very displeased with it since day one.
