I checked the fluid level on my 2007 SL hydraulic pump reservoir it appears to be slightly low and I noticed the reservoir is now facing towards the front (driver) instead of to the back as was the case on my 2004 model.

Also there is a plug on top and one in the middle of the reservoir side wall (front)
So which plug is the fill and which one is the bleed plug are there any procedures for flushing this model year reservoir.

I'll like to do a system flush as part of preventive maintenance.

Thanks
