traditional handbrake when hill start to rely on driving or by manually releasing the handbrake skilled throttle, clutch cooperate to ease starting. AUTOHOLD the automatic parking function is given by the gradient sensor accurate parking force by the controller, the information at startup, the parking control unit via a clutch from the sensor, the clutch kneading speed sensor, an accelerator pedal sensor or the like provided by computing, when a driving the parking brake is automatically released when the force is greater than the running resistance, so that the car can be smoothly started.
Even in peacetime Sese go urban driving, as long as you enable AUTOHOLD function, it will start the appropriate automatic parking function.
