Abstract

A remote start-up method of a manual transmission vehicle is provided. The method includes a parking braking force-associated remote start-up control that remotely starts-up an inclined parking vehicle parked on a ramp by confirming a situation where the parking braking force is maintained by a braking hydraulic pressure control of an electronic stability control (ESC) system in a remote start-up controller.
