Secrets feature: I found these on the W204 forum.

[Klinh]

any interest in one of these? i know there are some things that our dealers didn't explain to us that i had to learn after the fact. it might be a good idea to have a running thread as we figure things out... 1) aux input in glove compartment. 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. 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. 13) when the sun / Pano roof is left open on an extremely hot sunny day, the car will automatically close it (tilt position) after a while ( when the car is parked) (euro p2 version only) 14) 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 ) (possible euro p2 only) 15) PRE-SAFE system, which automatically closes open windows, sunroof, and move the seats, headrest + steering wheel to a more protective position - all done within milliseconds as soon as the car senses that an accident is imminent. 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. 16) rollbackassist : if i am on steep hills, i notice a roll back assist engages. I think it might happen if i press down on the brakes a bit harder. Release and the car holds itself for a few seconds before rolling back. Works Great! 17) autosense wipers that actually work! 18) on the cruise control stalk: If you push the stalk all the way up, it will increase the speed to the next 5mph increment (ie 52 goes to 55). If you push it down it will decrease the speed to the next 5mph increment (ie 58 goes to 55). 19) this is not somthing you can controll but the new W204 also has vents behind the rear wheels that exit out of the tail lights to keep them clean but more inportantly helps to give the car an overall drag coeffienecy of ONLY .29 20) with the MM the stereos volume will raise if you enter an area with loud noise. 21) If you have the transmission in C, and you punch off the line hard, it uses 1st gear, not second. 22) Leave your headlights in Auto mode & the parking lights & fogs will remain lit when you arm or disarm your car when it is dark. 23) Little arrow on the fuel gauge points to the side of the car that the fuel filler is on. 24) While listening to a cd, the music register or satelite radio, we all know that sometimes you can't read the full title of the song playing. Just press the # button on the dash and you will see the full title and the artist. 25) * key will allow you to jump to a specific track or radio station 26) If you have previously engaged your cruise control at lets say 70mph and are off cruse control but want to reset it to your current speed, raise the cruise control lever to the up position. This will reset it to your current speed where if you pulled the lever towards you, you'll be returned to the previous set speed. 27) slight tap on blinker gives a short 3 blinks for lane changes 28) if you use two fingers you can do all fore windows at the same time, up or down. 29) when the trunk is up and you're still in the driver's seat, you can see out the back, through the center mirror. The hinge lifts up and away, letting you see oncoming traffic before you open the door. 30) Auto dimming mirrors get light when in reverse. 31) dial mounted on the center console will not allow you to change stations or functions display unit unless the hood is raised. 32) In autos, u dont have to turn the ignition key all the way to start the vehicle. in other words, car can start before u complete the turn of the key. Also the car won’t let you re-try the ignition if the car is already on. 33) hood can be pushed up to 90 degrees while open 34) Discovered this feature yesterday. I had the wipers on permanent, not auto intermittent. When I stopped at a traffic light, rather than continuing on wiping permanently, it went into auto intermitent mode by itself. Then as soon as I started driving again, it reverted back to permanent wiping. 35) Wipers, will auto stop when the car stops, then resume when you start driving, with an occasional wipe as needed. This functions works in any mode you have your wipers on. It is dependent on how much it is raining. If it is raining alot dont expect them to stop. 36) Also when you are going down hill with your foot off the gas or on the brake, the car will shift down the tranny so you will have more controll and power to the wheels if you need it. 37) you only get the beep beep beep on the alarm if you actually have an alarm. otherwise just lights will flash. 38) tilt down mirror won't tilt down if you're backing up quickly 39) tunnel mode is available on the 2009 w204 (hold down air-recirculation button) 40) trunk has emergency release on the inside that stays lit for 60 minutes after closing. w204 secrets thread...

No flame but did you even STFF W203, W209 secrets and/or RTFM. A lot of those are incorporated into your model which happens to be based on the W203. Maybe you ought to STFF W209 and W203 and post commonalities.

[supacrazykev]

like a "click sound" lol and it came from somewhere btwn your steering wheel and your cluster...not saying exactly there but u have to listen carefully....or maybe your car is different I did that to my clk320 but let me try on my 500 this week...I'll get you back on this. Why not ask Klinh see if he done that already ?

Andy

[BadBlack550]

39) tunnel mode is available on the 2009 w204 (hold down air-recirculation button)

1a) not all will have it

28) he means you press all 4 buttons at the same time by pressing front ones together and rear ones together

38) there is a setting in the menu to activate this functionality

39) it works on my 2003 clk320, if windows are open it closes them, but will not close the sunroof
---------

33) hood can be pushed up to 90 degrees while open

This is very helpful and looks cool, but make sure you press the red button on the driver side arm when lifting over the normal angle. Also make sure your garage doors are high enough so you don't break your hood when you open them no I did not do that

37) you only get the beep beep beep on the alarm if you actually have an alarm. otherwise just lights will flash.

Interesting, so I do not have an alarm?

41) Turn your key to on position. Then to Off press the reset button three times quickly. Turn the key back to on.

does not work with 2003 models

-------------

Anyone knows if there is a way to auto close all windows and sunroof with out having to hold the key by the sensor on the door handle until it all closes? Would be nice to e able to do it with one sequence and walk away.

Oops I think it might be Turn the Key to start position then to off position press the reset button 3 times quickly. Your voltage for your battery will come up. If you scroll through the menu, You can also turn the car into Dyno Mode, which i think turns off traction control and abs.

[BadBlack550]

May be its just me, but I could not get to Dyno mode, or find where you turn on the mirror lowering in reverse feature, nor get in the tunnel mode.

[supacrazykev]

Letme figure out the exact detail today

[Trekman]

if you rub the star on your steering wheel 3 times you can call on the Mercedes Genie. J/k

thanks for the info

Well my does not beep but the VIN listing shows the alarm "551 - anti-theft/anti-break-in warning system with anti-towing system (с 01.04.1998)"

Go in to the menu system, menu 6 (Settings)
Select convenience submenu
You should see: Set parking position for exterior rear view mirror
Page 118, 133 in the menu

[BadBlack550]
