If your Schumacher Remote Starter isn't jump starting your car, there are several potential causes: * Ensure the Jump Start/USB Switch is turned ON. * Check the battery connections, ensuring they are clean and making good contact. Rock the clips back and forth to improve the connection. * Verify that the Instant Power™ battery is charged. Check the battery charge status by pressing the button on the front of the unit. Refer to the DIGITAL DISPLAY FUNCTIONS section for details. * The vehicle’s battery may be defective. Have it checked by a professional.
