The auxiliary battery of the Mercedes-Benz GLC260 is located on the right side of the trunk. The auxiliary battery refers to the battery that powers the entertainment system, windows, and lighting system during startup. Reasons for auxiliary battery failure: 1. Insufficient battery power; 2. Damaged auxiliary battery; 3. Generator or charging system failure; 4. Related circuit failure; 5. Auxiliary battery fuse damage. The Mercedes-Benz GLC260 is a mid-size SUV under Beijing Benz, with body dimensions of 4764mm in length, 1898mm in width, and 1642mm in height, and a wheelbase of 2973mm. It is equipped with a 2.0T 197 horsepower L4 engine and a 9-speed automatic transmission.
As a seasoned car enthusiast, locating the auxiliary battery in a Mercedes-Benz GLC260 is quite straightforward. It's typically hidden at the bottom of the rear trunk. After lifting the luggage compartment cover, you'll need to pull up the carpet or remove a plastic cover panel, commonly found on the inner left side. Why is it important? This battery powers auxiliary systems like the start-stop function, and a depleted battery can prevent the car from starting. I've replaced mine once—first disconnect the car's power to avoid short circuits, then use simple tools to remove the cover. Pro tip: If your car suddenly has trouble starting, check here first before rushing to replace the main battery. However, non-professionals should visit an authorized dealer for safety. During routine maintenance, clean the terminals to prevent corrosion and extend lifespan. Remember, safety first—never work on it while powered.
As an average car owner, the first thing I did after purchasing a Mercedes-Benz GLC260 was to familiarize myself with these small details. The auxiliary battery is hidden under the trunk floor, specifically beneath the left or right cover panel—just lift the felt mat to access it. It plays a significant role by assisting the main battery in power supply; if it runs low, the car will display a warning light. Once, I encountered a starting issue and found a loose connection here—tightening it solved the problem. After learning its location, I regularly check the battery voltage myself with a voltmeter to avoid unnecessary trips to the shop. For beginners, I recommend first reviewing the illustrated owner’s manual to prevent accidental part removal or damage. Overall, it’s quite simple—keeping the battery dry during daily use can prevent unexpected issues.
