Warning: 1. Before working with your vehicle’s battery, always consult the battery manufacturer’s and vehicle manufacturer’s safety instructions, warnings, and guidelines for battery disconnection, removal, and replacement. 2. While the memory saver is active, the vehicle’s electrical system remains powered through the OBD II connection—meaning battery terminals stay electrically live. Cover them with insulating material to prevent accidental contact with metal surfaces or each other, which could cause a short circuit. After each use, disconnect the memory saver and clean connectors and cable with a dry cloth to remove dirt or oil. 3. During battery replacement, DO NOT turn the ignition ON (including ACC ON), especially when the old battery is disconnected and the new battery is not yet fully installed. Doing so may cause excessive current draw and blow the memory saver’s fuse. 4. Securely insert the OBD II connector of the memory saver into your vehicle’s OBD II port to ensure solid contact; poor connection during battery replacement may result in intermittent or lost power to the ECU (Electronic Control Unit, also known as auto computer).
