Traction Control5 keeps the rear wheels from spinning, eliminating fishtailing to help keep the car under control. Oddly enough, this slowing of tires actually helps you accelerate faster.
ESC is the automotive equivalent of dipping an oar into the water. It uses your brakes to help you make crisp turns in less-than-ideal conditions. It corrects your intended direction by braking an inside wheel if you understeer and an outside wheel if you oversteer5.
ABS pumps the brakes when you brake hard to prevent the wheels from locking up.
EBD works with ABS and applies brake pressure properly to help keep the car stable while braking.
Research found that in the event of an emergency, people often don’t press the brakes hard enough. Brake Assist recognizes these situations and automatically gives that extra effort.
