To jump-start a Volvo S40, first ensure both vehicles are turned off. Connect the positive (+) terminal of the dead battery to the positive terminal of the working battery, then connect the negative (-) terminal of the working battery to a grounded metal surface on the dead vehicle. Start the working vehicle and let it run for a few minutes before attempting to start the Volvo. Once started, remove the jumper cables in the reverse order, ensuring not to let the clamps touch each other.
