There's a long discussion on this in the SLK section:
https://mbworld.org/forums/slk-class-r171/186557-question-sport-comfort-switching.html

One of my posts that describes the S-C-M switch:

The SLK55 has 3 modes on that button: Sport, Comfort and Manual.

I have the SLK350 with the 7-speed automatic. My button only has 2 modes: Sport and Comfort.

To get to Manual, I have to nudge the shift lever to the left or right to choose a gear limit (1 through 7)

Towards the end, the general consensus for switching between modes:
Put the car in Park or at least stop the car when switching modes. Switching while in motion is not recommended.

sorry i brought this up earlier but it got buried in the thread ...does anyone have any comments on this?

I also use W-mode in a trafficjam, so it won't shift op and down between first
and second gear every few meters.

Since we were somewhat on topic of gas mileage...I wanted to ask you all...I have the '03 C230 (just to clarify because I don't know if they altered the menu's of the newer C230s)...and when you go to the menu on your dashboard to check your MPG...there are 2 menus...one that says "...MPG Since Start..." and another that says "MPH since Reset..."....can anybody tell me the difference between the two? I can reset both menus...so wouldn't one cancel out the other? I have no idea what is the "MPG Since Start" menu is about...but the "MPG since Reset" menu is clear to me.

MPG since start is when the car has been sitting for a while, the information returns to 0

MPG since reset is from when you last reset the information. That only changes when you hold down the reset button to 0 out the details (much like the overall mileage screen).

Thank you very much drex! (congrats again on becoming a mod.)

drexappeal

Thanks, but been a mod since last June or July '06 (can't remember which month). nlpamg is the one that just got promoted

We're all the same generic pinoy anyway :p. Yo bro, I've noticed recently that I've done a few modifications with the intercooler rubber encasing - I think this second time around my IC gets more air, especially with the B front.

Gonna attempt running in C mode for this gas tank to see if it makes a difference on my car's gas mileage (since it's not exactly stock anymore). I'll report my findings when this tank is done.

We leave my wife's in sport...99% of the time. I do not think it matters if you are driving or not...when you put it in sport or comfort

Moviela

The processor on the transmission waits for a "motion clear" (ouput shaft stopped) before entering the other mode. Some versions also check that the shift lever is in park.

c230K415

Sorry drex haha! It was late and I don't know why but I constantly get you and nlpamg mixed up (no offense). Oh! but you still are a good mod nonetheless haha.

sports mode

Wow, almost $4 for premium?? I just paid $2.70ish for premium yesterday.

drexappeal

No prob! I figured it was somethin' like that. I blame it on the damn Cali weather right now. It's so up and down that it has everybody messed up

Moviela, didn't know about S not having hill-holder mode. Now I gotta find a hill to try this out. Been driving this car in W mode 99% of the time since I bought the car, and hill holder is awesome. 1st gear in this car is pretty much useless unless you like driving the car like you just stole it.

imo it would have been nicer if they changed the different gear ratio so that the 1st gear acted more like 2nd gear and just got rid of the button (I'm talking 5-speed auto here), then you'd really save some gas on the highway, especially when cruising. One does not need 2500rpm at 100km/h unless he/she is always passing people, 2000rpm is more like it. Anyone selling a differential with a lower gear ratio? :p

Yes, for MY2002-2003 the switch says Winter/Summer and for 2004+ it says Comfort/Sport.

You can switch modes when driving, though it only makes a difference if you are driving very slowly. Try rolling very slowly (ie under 10km/h) and start pushing the button. You can feel feel the car switch between 1st and 2nd. I do that red lights when I'm bored.

pmb600

They probably changed the W/S to C/S because many people might have thought that they could only use W mode in the winter or they might damage the car or something. I did try using C today and I got better mileage, but I also was driving more calmly than I usually do. I will have to try this later again.

Not in my car

Lets see...I put mine (2003 C240) in W mode for my ride to and from work, which is not far, however, I really like how it feels compared to S mode. My question is...I'm a maniac and drive fast sometimes...is W mode good for speeding/highway driving? I also do a lot of city driving...back and forth to work/school and sometimes Boston. Which is best for me do you think? I've been following the thread, and in all honesty, I'm not clear of everything thats been mentioned..I'll be driving a bit more tomorrow, and I'm gonna leave it in W mode...

themerc

Yes, you can drive highway+ speeds in W(C) mode.
If your car is an auto-tranny, it probably won't downshift as soon as it would in S mode for a given gas pedal deflection; which is part of the nature of W(C) at any speed.

LuxuryC240

Ok thanks....well recently, while driving in S mode, I've noticed that it seems to be downshifting rather soon, and feels kinds jerky, I dunno, it just started being a little different...And yes, in W mode, the car rolls longer and sort of faster, for instance driving on a regular, say 30-35mph road without your foot on the gas...in S mode, if I take my foot off the gas, it downshifts by itself sort of quick...am I feeling things or does this sound logical?

pmb600

No I think your perceptions are accurate. I prefer the C mode for most driving since the trans definately does not jerk as much. However, like you sometimes I like to drive fast, but our car is not that fast to begin with. The S mode seriously helps it and it has much more thrust when you put it in S.

themerc

I think the S mode programming has it downshift sooner, or more proactively - depending on the conditions.
If I'm coasting to a stop going slightly uphill, in S mode it will downshift to keep the car in - or closer to - a more appropriate gear for acceleration from that point. Doing this uses a little more fuel, but it's also more ready to go. The same scenario in W(C), and it doesn't downshift nearly as soon - unless you then aggressively press the gas pedal.
