Jack point W220
Can anyone tell me where the safest place is to place the lift pad of a floor jack under my 2005 S500 4MATIC? I plan on using Tire Rack for my next set of tires and don't fully trust my local tire shop to know where to put the floor jack when they lift the car. Any other comments, horror stories, etc., relating to use of local tire shop would be appreciatied.

You can lift these cars DuH! How else would you change a basic flat?? Would you buy a car that you couldn't even jack up to change a tire?? I think not...
Richard there are jack pads located just forward of the rear wheelwell, or just aft for the front wheel well...
Otherwise you should remove the plastic cover from the lower rocker panel and use your factory jack.
If you are swapping wheels you canuse two 2x4's on a hydraulic jack placed between the jack pads in the middle of the car centered just aft of the drivers door and it will lift both the front and the rear of the car. This where the center of gravity is..
DO Turn on the ignition while the car is off the ground. and dont worry if it seems high when you let it down this is normal for air suspension..... as soon as you roll it will level out right away.
WHich wheels and tires are you getting from TR?

Thank you for your comments. I am not planning on jacking the car myself unless of course I have a flat tire. I want to make sure I can give guidance to my local privately owned tire shop who has provided years of quality service to my BMW 528, BMW X5, 2 Ford Expeditions, and now S500 4MATIC. I only need one tire installed at the moment. I have 3 new Goodyear RS-A All Weather tires and one that is about 60% tread. I want to bring them all up to 100%. I don't know what I'll buy next. I'll be perusing the user groups for ideas all of this coming spring. I'm looking for value and mileage. I'm not too heavy on the throttle so performance has to be weighed along with mileage and cost.

Do you mean DO NOT TURN ON THE IGNITION while the car if off the ground?

IF you do, you car will sense the height has changes and try to bleed you system. It may sit on the ground if you do and you will have to keep weight on the wheels till it pumps back up to keep from blowing your struts.
This may or may not happen.. its just safe to leave the FOB in your pocket while wheels are off the ground. prevents unwanted problems Ya'Know...

stands under the jack points and let the car back down on them.

OK, I think I'm 'good' when it comes to jack points. They are located directly underneath the jack points that have the plastic covers. They are round nubs about 2" in diameter and maybe 1/2" high. ..and it makes the most sense to use 4 floor jacks or a lift when stripping all the tires off of the car at once.
My next question is: Do you have to loosen or remove the pressure sensors before using the tire removal machine? Any tips relating to changing tires would be useful, i.e. what makes the 5 spoke AMG wheel different from the perspective of a tire mechanic?
My Expedition has a very similar setup and I have never had a problem changing tires.

what supports the 2x4 in the center where he is about to place his floor jack? half the weight of a 3800lb car being lifted by a 2x4?.if you can lift the car without snapping the board in the center at least put two jack stands under the jack points and let the car back down on them.
stands under the jack points and let the car back down on them.Of course you can't jack the car with a 2X4...
But you can put a Hyd.jack at the point where I specified and use a peice of 2x4 or any stable shim of your choice between the jack and the frame since there is no pad there and it will lift the car evenly front to back.
I "pitstop" rotate my tires like this all the time.
Of course two jacks are okay also..if you have two..
Your car must be awfully high off the ground to be able to fit jack stands under the pads... there is no need to raise a vehicle that far off the ground to change a tire....

Are you serious?? I would strongly suggest thinking about getting someone who has changed a tire before to do this job for you.. For and experienced tire person, there is no big issue between certain rims... for the shade tree guy, you are asking for trouble... don't do it.

My post must be a little misleading and I do appreciate everyone's comments.
My local tire shop does all the work on 2 Expeditions, a BMW528 with snowflake wheels, and my wife's X5. They do a great job on these cars. I'm just mining for information/tips on the Mercedes wheels in an attempt to avoid downstream issues. As good as they are, they are not my Mercedes dealer.

No where near as big a deal as some would like it to be. If your local shop has done good work before I dont see any reason to doubt them now...
IT is IMO certainly an overkill to to this at the dealer.. They aren't tire experts either.

you are correct,
You didn't understand what i was saying.....
Of course you can't jack the car with a 2X4...
But you can put a Hyd.jack at the point where I specified and use a peice of 2x4 or any stable shim of your choice between the jack and the frame since there is no pad there and it will lift the car evenly front to back.
I "pitstop" rotate my tires like this all the time.
Of course two jacks are okay also..if you have two..
Your car must be awfully high off the ground to be able to fit jack stands under the pads... there is no need to raise a vehicle that far off the ground to change a tire....

i read the thread again and you did refer to using two 2x4's.i still cant agree with centering the jack in the middle of the car,unibody's dont like to support weight in this manner.the jacking point locations are enginered to lift the weight as closely as possible to it's mass with minimal body deflection.you may not see it happening but when you place the jack at the center of gravity and lift,the the car is bending in the center,the 2x4 shim is focusing the lift point in that specific area.remember geometry?? if you apply force to one side of a car while it is on the ground on th other side, you are not lifting half the weight of the vehicle, in fact, it may only be about +/- 700 lbs of force to raise both wheels of the car off the ground. this is less than 25% of gvw. He body of a YUGO was more sturdier than that.
When you use a jack point or move the same force to a corner of the vehicle you then have 3 points of weight support so your lifting force is even less.. like 400Lbs of force.
So.. yes it will support lifting from the center,and yes the frame will flex some as its designed to do but there is no risk if damaging the body or anything... you just have to mind how you do it. Like I said this frame has to be a lot stronger than you are giving credit for..
keep in mind when your car is put on a lift at the dealer and tire shops for example, it is lifted on both sides at the points between the jack pads...

ok,ill accept that
Good point but I think if such an expensive car was that flimsy in the center, id be driving a much less expensive one.....But I don't think its that dramatic...

I have two sets of tires/wheels for summer and winter. When changing I use a floor jack under the rubber jack points. I always have the vehicle off and have the parking brake on. Along with stops under the tires that are still on the ground. I also use a rubber pad between the jack and car, so no metal from the jack is touching the car. One corner at a time is changed. I would never use anything to jack one side of the car. That's how people end up dead stuck under the car. Don't let your car kill you!
