Hello all, I have tried reading through a lot of threads. Here is what I got.

I have a 2004 cl500 New to Me last Year 65K miles love the car. Actually bought it for my wife as a surprise. I left the keys in the car the other night not sure if I left a light on or something else. Next morning Battery was completely dead, Put a jump box on it got it started let it run for a while in driveway. Drove it that night, The SRS light came on and also got a teleaide/sos error on the display, Neither went away, but also the power door locks stopped working from the key Fob as well as the lock/unlock buttons in the car stopped working, also the rear window shade stopped working. I haven't gone through every button or switch, I feel all has to be related to the battery going dead . since all of these things showed up at once ???

Any Thoughts or suggestions. I have not looked at any fuses I have read the SRS light I might have to get reset at the dealer.

When sitting in the car and I hit the power door lock button I do hear a hum sound or power sound not sure if that means anything.

I put a charger on the battery today to try and charge the battery more. By the way it is a brand new battery 2 months old

Ill try anything before getting raked over the register at the dealer.

Thanks for any help in advance.

Yes you need to fully charge the battery
Then if there are any lingering errors do the resets mentioned here

A small Update I pulled a few fuses no Luck, now the back headrests wont operate up or down, I found the PSE pump and when I hit the key fob button to lock or unlock I hear the pump running according to when I hit the buttons but nothing happens with thr lock, the LED on the Lock button is now flashing

any thoughts I can't find anything on the reset for the locks, can you guide me a little more

Thanks
