Noticed the sunroof becoming sticky on closing. Got me to wandering what to do if stuck open. I remember on my E320 that happened and there was a hex wrench in the glove box that allowed you to manually close it. I also found a manual for a 2007 GL for closing it in emergency but nothing for the 2009. There is NADA in the manual about an emergency closing procedure. Also, there is not a wrench in the glove box or in the kit with the spare tire taht would work. Same over on my 2010 S550. Any help or am I just missing the wrench>? But why noting in manual?
