THINGS I DIDN'T KNOW ABOUT MY R CLASS
To set the rear hatch height limiter, the key has to be in position two (run), and then follow procedure in the manual with the close / stop button. The key position is not mentioned in the manual. Hint: Remember to shut the key off after programing or the starting battery will drain.

1. If you have automatic wipers, the rear ones go on when backing out of a spot in inclement weather
2. If you press and hold the recirculating button of the ac, all the windows including pano roof will close automatically.
3. Holding the unlock/lock button from the smart key will open or close all windows.
4. Pressing the windshield washer 5x consecutively will activate headlamp washers
5. RAINX will solve the vibrating wiper problem that everyone has, instead of wasting $$ on a new set every few months or so
6. The car auto levels itself (raises or lowers) when loading or unloading
7. On a red light on a steep incline the cars doesn't roll back for a few seconds after releasing the brake.
8. Pressing on the red tab on the hood lifters (whatever you call those) will allow you to open it up to almost vertical position.
9. When a brake light goes out, there is a reserve light for both sides.
10. Pushing the a/c recirc button after the engine is off will keep the cabin heated as long as there is heat and a good battery.
11. You can orient the map/nav unit north up or in the direction your heading
12. If the engine runs, and the car is stopped after driving (i.e. stop light) if you open the door the car goes into park by itself (safety measure?)
13. The analog clock in the central instrument cluster and the digital one in the Command are both linked together to the GPS. (Assuming you have GPS)


1. This seems to only occur if you have the rain sensing wipers left on at startup. I have an acquaintance with an E350 and his front wipers do a startup sweep if he leaves them on.
2. I tried this on my 2010 and it does not seem to work that way, at least for the newer models.
3. This works, but I think it works off of infrared so you have to stand by the drivers door and point the end of the key at the door. You can see the infrared sensor on the door.
4. Very few newer if any new models have headlight washers installed. I think it used to come only with the HID lights, but no longer. I don't have HID so I could be wrong.

Was looking under the car after installing a hitch and was wondering what those big rubber bags and interesting articulated sensor was. Hey self leveling rear suspension is standard!
One thing that would be nice would be to be able to turn off rear hatch control completely. I have a trailer hitch mounted bike rack and did put a rubber pad on the rack. The hatch will stop after hitting it lightly without dammage, but would be great to turn it off completely, say for when backing into a parking spot with a concrete wall or other solid object. Better yet a sensor. Many times I have raised the hatch only to hit a low pipe in an underground garage. yes I know I can set it to half height, but I forget!
