Where is the auxiliary battery of the GLC260 located?
2 Answers
The auxiliary battery of the GLC260 is located on the right side of the trunk. The auxiliary battery generally refers to the battery that powers the entertainment system, windows, and lighting system during startup. The function of the GLC260 auxiliary battery is to supply power to the electrical appliances in use when starting the engine. The GLC260 is a mid-size SUV under the Mercedes-Benz brand, with body dimensions of 4764mm in length, 1898mm in width, and 1642mm in height, and a wheelbase of 2973mm. In terms of power, the GLC260 is equipped with two engines: one is a low-power version 2.0-liter turbocharged engine, and the other is a high-power version 2.0-liter turbocharged engine.
My GLC260's auxiliary battery is located under the trunk floor. After lifting the carpet, you'll see a black plastic cover next to the spare tire and some tool compartments. It took me some time to find it initially because you need a flathead screwdriver to pry open the cover, which has securing clips inside. This battery mainly supports the auto start-stop system and electronic stability devices. If it malfunctions, you may feel jerking during engine startup or see dashboard error messages. I recommend regular checks—if the battery ages, it's best to replace it with genuine parts at an authorized dealership to avoid compromising driving safety. I bought a multimeter to test the voltage; it should generally stay above 12 volts—anything lower requires immediate attention. Always disconnect the negative terminal during removal to prevent short circuits, and insulated gloves add safety. The location is quite hidden but not hard to find—consulting the user manual or online tutorial videos can save a lot of hassle.
