I will leave my GLS 350d inside garage for two months. I would like to disconnect the negative terminal connection, but do not how to find it and how to disconnect it.
I will appreciate it if someone can show me how to do, it will be better with photos.
Great thanks.

You might consider using a battery tender instead of disconnecting the battery. You'll be unhappy when you find our where the battery is.

I could do you a picture, but since your steering column is in the wrong place it wont be the same as mine.

Just in case they mirrored it : open the hood (or bonnet, or whatever you call it) and look at the top of the inside of the inner wing : you should see a metal pin there, about 4 cm long and 1 cm in diameter : that's the earth connection for the jump starter cables. There's a think black wire attached to it. Follow it straight back inder a plastic cover (upper right corner of the engine compartment) ant it shouuld be there.
That said, disconnecting the battery is a bit of a last resort. Use a conditioner when at all possible.

thanks for all of replies. I will buy one battery charger and ask the dealer for the right connection.

Don't buy a cheap battery charger.... Battery Tender is a known good brand.....

My dealer quoted US$ 180 for a "Mercedes" battery tender.
I bought a Battery Tender Plus on Amazon for US$ 45. Your choice.

CTEK makes all the european oem trickle chargers, 60 bucks on amazon. It also reconditions if necessary use it overnight every 6mths and you never have to worry about a dead battery. Better yet, since it desulfates yhe battery it can more yhan double you battery life. Worth every penny. Furrhermore, since it a general purpose model you can use it on any battery type.
