Clarifying What Is Accessory Mode for Your Vehicle
Accessory mode lets your vehicle run non-essential systems. It delivers just enough energy for lights, the infotainment system, and a few other comforts while the engine remains off.
Recognizing the Advantages of the Engine Accessory Setting
Using accessory mode can save fuel, prevent unnecessary wear on the engine, and allow you to enjoy the car’s comforts during short stops. It is especially useful for setting up your music video, checking your smart key, or simply enjoying climate control without a full engine start.
Differentiating Accessory Mode From the Engine on Position
While engine on means full power and running, accessory mode uses a much lower power level. This mode prevents the engine from warming up and protects vital parts like the oil filter and cylinder head from unnecessary strain.
Identifying Systems Powered by the Engine Accessory Feature
Systems such as the radio, dashboard indicators, and sometimes the power steering enjoy power during accessory operation. These features get just enough energy to keep you connected, without engaging high-power components like the fuel pump or alternator.
