Learn through this video tutorial how to replace the auxiliary battery in a Mercedes CLA. First, you need to know where it is located. The auxiliary battery is installed inside the cabin, in front of the passenger's feet.

To change it, you must first lift the carpet and then remove the panel covering the battery. To do this, you must first disassemble the cover of the cabin air filter box; otherwise, the panel will be stuck and cannot be removed.

Once this is done, you can disconnect the battery terminals, remove the old battery, and insert the new one in its place.
