How do you jump start another car using Volvo s60?

To jump-start another car using a Volvo S60, first ensure both vehicles are turned off. Connect the red positive jumper cable to the positive terminal of the dead battery, then attach the other end to the positive terminal of the Volvo's battery. Next, connect the black negative cable to the negative terminal of the Volvo's battery and attach the other end to an unpainted metal surface on the car with the dead battery. Start the Volvo and let it run for a few minutes before attempting to start the other vehicle.
