2006 Mercedes-Benz CLS500 Q&A
2006 Mercedes-Benz CLS500 Question: battery location?
I believe the battery is under the rear seats or perhaps in the trunk. Try a Mercedes fan forum, or subscribe to something like www.alldatadiy.com to get the specifics. - matte
There are two batteries on the CLS500. the main battery is located in the trunk on the passenger side under the trunk mat. There is also a small 12 AH auxillary battery located under the hood beneath the cabin air filter housing, passenger side. This aux battery maintains the electrical system in case the main battery is discharged. It will not start the car. - Visitor
