I noticed yesterday if you press the brake pedal all the way down or hard enough at a light while in Drive it will engage a traction control little light on the dash for like 5 seconds while beeping and the car will sit on a stand still during those 5 seconds

What is that for?? Is it a special feature for your 30000hp race car lol lol

 

never mind, did a search and found out it is some feature called hill assist. even a prius has it so nothing special lol

 

That's the Brake Hill Holder that you activated. Prevents you from rolling back when stopped on inclines and gives you enough time to get on the gas after releasing the brakes without rolling backwards.
