If for whatever reason(s) you have an external Battery Tender/Charger in Use you MUST Disconnect it prior to starting cars engine.

- Do Not start the engine with a connected 12V battery charger because the power supply from the DC-DC converter and the power supply from the 12V battery charger may interfere then warning light comes up and DTCs will be stored with set warning lights in Instrument Cluster.

Again disconnect any Battery Chargers before you start your CX-60.
