Toyota Corolla (E210): Brake Hold
The brake hold system keeps the brake applied when the shift lever is in D, B (vehicles without paddle shift switches), M (vehicles with paddle shift switches) or N with the system on and the brake pedal has been depressed to stop the vehicle.
The system releases the brake when the accelerator pedal is depressed with the shift lever in D, B (vehicles without paddle shift switches) or M (vehicles with paddle shift switches) to allow smooth start off.
