The sophisticated Toyota system is an all-speed design that utilizes both brake and engine throttle control. TRAC helps to avoid slippage of the driving wheels by slightly applying the brake on a slipping drive wheel and reducing the throttle to maintain traction according to the road surface conditions. The system eliminates the need for a subtle accelerator pedal operation and helps ensure vehicle control when starting or accelerating on slippery roads.
