w204 secrets thread...
1a) if you have ipod integration, the aux input is tucked away under the plastic cover
2) aux input is accessed from cd menu (in my non-multimedia pkg)
3) hold alarm on/off pointed at small square on driver's-side door handle to open/close sunroof and windows
4) power source in glove box is 12v switched (i remember there was some discussion about that)
5) if you have the automatic tranny, push the stick to the left and hold it there, it'll downshift to the gear lowest possible to allow you to be in the powerband to pass cars. And pushing the stick to the right side and hold it there will put you back into the normal automatic shifting mode.
6) Little arrow on the fuel gauge points to the side of the car that the fuel filler is on.
7) there is a way to reset your service indicators and other lighting options by pressing the OK and TALK button I believe.
8) badges in back leave no holes except for the star
this is a new one for me.. i gotta go find it now! is it still functional?

9) A slight tap of up or down on the turn signal tree allows the turn signal to flash 3-4 times for a lane change and then shuts off automatically. No need to full engage the turn signal and shut it off manually.
10) Steps to Reset the TCU. Resetting the TCU will reset transmission to factory shift points and the car will 'relearn' your driving style.
(1.) Turn the ignition key to the on (not start) position.
(2.) Press the gas pedal to the floor and hold for five seconds.
(3.) Turn the key to the "off" position (don't remove the key), then release the gas pedal.
(4.) Wait at least two minutes for TCU to reset.
11) brake rotors stay at peak efficiency from feathering initiated after a certain number of windshield wipes during rain.
12) headlamp cleaners activate every 10 windshield washes.

car will automatically close it (tilt position) after a while ( when the car is
parked )
2. Again if the car is equipped with Sun/Pano roof as well as rain sensing
wipers, the car will again close (tilt position) the roof as soon as the sensors
detect rain ( when the car is parked )
Key in position 0 or out of ignition.

1.Turn your ignition in first position
2.Press and hold the accept call button for 5 seconds and while pressing press the ok button on the steering wheel.
3.If needed after releasing the two buttons press ok once more.
This should allow you to reset and it also the secret way to completely disable ESP (not recommended unless you want to spin out of control and burn through your tires). Be careful!

This is the 2nd stage of pro-safe. First stage is the passive pre-emptive measure, like ESP etc. The 3rd stage is post an accident, which includes automatice shut down of engine and cutting off fuel supply + turning on hazards lights + lowering windows slightly + unlocking all doors.
Given that stage 2 relies on power seats etc, it's probably not available in the US.
2) autosense wipers that actually work!

one of the lowest for this type fo car.
If you hold the open button it will open the windows and pano. Nice if you want to vent the car before you get in.
If your vents are going at full speed and you push the talk button it will adjust the vent speed to the lowest speed so your commands will be loud and clear =)
Having read through my manual, MB's real secret seems to be: - which frigging oil should you use to top up if necessary!

Leave your headlights in Auto mode & the parking lights & fogs will remain lit when you arm or disarm your car when it is dark.
