long term parking
I will leave the my 08 S550 in my garage for about 6 month because I have a long business trip in Asia.
I don't like to give my key to my friends or someone, then there is chance that he will drive my car. Writing down the mileage and things like that didn't work with my last Lexus. So I rather just take the key with me. I live myself, and so I don't have family who can start the car.
From experience with Lexus, I did disconnet the battery in the hood, then when I came back, reconnect it then start the car. I remember that the car had rough engine noise for first few second then, it was fine.
For the Mercedes, I know there is command, and more electronic stuff, I am afraid that if I disconnect the battery, it will have alot of error message when I reconnect. Also I know that engine oils will be bad condition in about 6 month. I want to know if I have to change the oil before I leave.
I will replace the tires after I come back. It is almost there to replace.
Please give me some advise for long term no use parking.
Thanks.

No, I'm sorry that was rude. I would just park it, garaged, car cover, battery connected and all.
Anyway,,, is battery will last for 6 month?
Actually, for the lexus, it stated to beep the alarm because of low battery in my apartment garage until all battery drained. When I came back from trip, everybody who I know told me " Your car was crasy every night."
I don't want that happen again.....

Disconnect the thing.

The car would start up with a flat rear battery (using the starter battery at the engine bay) but it is not good for the main battery if it remains flat for a long time.
