Step-by-step explanation:
True, when driving a manual transmission car, it is generally recommended to downshift before starting down a hill. Downshifting helps to maintain control of the vehicle and provides engine braking, which can help to control speed and reduce wear on the brakes. By downshifting, the driver can utilize the engine's compression to slow down the car rather than relying solely on the brakes.
