I've heard that the engine mode switches back to Eco on each restart to pass the US Emissions laws.

I only have Economy or Sport on mine, the manual mode engages when I start using the paddles. I haven't noticed it go back into automatic, maybe I'm not leaving it in manual for long enough

The ride height switch just raises the car up. I've only used it once when the roads were slightly flooded.

The laggy/lazy throttle response really bothers me too. I've read some posts on here and it sounds like a remap will remove/reduce the lag.

Sport mode is more responsive than Economy mode for your transmission setting (starting in 1st gear versus 2nd gear), so the lag will be less. However, if you are trying to emulate a more sports car like responsiveness, you're not going to achieve that. These are of course GT type cars, not sports cars. You could go the tuner route, but that has the potential to impact your power train warranty.
You can buy something called a sprint booster that will change the signal level going to the ECU, so it will take less pedal travel and give you the feel of a more linear pedal response on acceleration. There are several threads on this forum about sprint booster, so you should find plenty of info on the product.
There is a third party product from Mid City engineering that will allow ECO start / stop to be default off instead of default on at start-up. Again, numerous threads here on ECO start / stop and Mid City. You just have to assess what not having to push two buttons at vehicle start-up is worth to you from a financial or annoyance perspective.
MB service will NOT either modify your standard transmission mappings or change the default operation of ECO Start / Stop for you. Lots of folks have tried that route and the response from MB service reps has always been no.
Hope this helps.

Thanks for the tips. I'll look into these options... the Sprint Booster might do the trick.

I wonder about the impact of the ECO start/stop on the starter, engine, and battery over time. It seems like the green thing to do but what's the long term impact?

While MB claims no impact to the starter, I personally don't buy it. If you use your car as a daily driver and are regularly stuck in bumper to bumper city traffic, a typical daily commute might involve 50 or more starts and stops. That is at least 250 additional restarts due to ECO Start / Stop each week. That is over 12K additional restarts a year. Sure if you only keep the car for three or four years, then the starter is likely to hold up that long and end up being a problem for the next owner. However, if you keep a vehicle longer or are the second or third owner, then the negligible gas saved by ECO isn't worth the shortened lifespan on the starter.

well, at least in Canada you get folding mirrors...

PaulE550

You get them in the U.S. too. Standard equipment as of 2015.

kaetamer

figures, i need them and ive got a 2014. rats!

TNTim

I need want them too - 2012 here. I can't believe they weren't included on US models until 2015

VirtualRain

Yeah but the number of times I really need them here... I'm not sure it's that compelling a feature with the parking facilities we have in North America. I can understand the need in Europe where streets are extremely narrow and parking space is at a premium. I guess they are handy for automated car washes. From my pessimistic viewpoint, it's just one more thing that's likely to break just after the warranty expires

VirtualRain

Yeah, that's a lot of added wear and tear on the affected components. I also notice that when my car restarts after I release the brake pedal, the restart not always a smooth process... there's a bit of a bump or movement in the car that's noticeable and not pleasant that I assume is coming from the drivetrain reloading with torque.

PaulE550

Honestly, after the first few weeks of ownership and seeing how little gasoline savings ECO was likely to produce (about 1 mpg on average), I simply got into the habit of disabling ECO Start /Stop upon starting the vehicle. Restart is always nice and smooth and no real vehicle shutter if I leave ECO Start / Stop on, but for making turns at a stop light you're adding an additional second or two. Which around here can get you T-boned real fast. So it's also a matter of personal safety as well for living in this area. To me, the gasoline savings is negligible for all the additional and unnecessary wear and tear ECO potentially causes. I generally keep a vehicle at least 7 to 10 years, if it is "a keeper", which this one is. So why accelerate the deterioration of a part that is a real pain to change? I had to swap out the starter motor in my Lexus a while back and you have to tear down the top half the engine to get at it. Took over four hours to do. I would expect having to do the starter motor on these M278 engines would take the same or longer. Anyway, enjoy your CLS. You'll have a blast driving it. Last of the non-AMG V8's.

VirtualRain

I agree. I think this will quickly become my MO as well.

BTW, you say "the last of the non-AMG V8s"... what are they doing with the new CLS for engines?

The eco-start feature has been around for many years now on pretty much the whole lineup of Mercedes. I haven't seen any major issues in the threads.

II have had my 2017 CLS550 for nearly a year and a half and have never had to raise the vehicle. The car lowers (I think) when in sport mode, and as one poster said previously, whenever the car goes over 70mph. Sport mode is a blast to drive in and totally changes the character of this car. As far as ECO mode start/stop, I never use it and it has become second nature to me that whenever I get in the car the first thing I do after starting the motor is pushing the button to disable the feature. I don't even think twice about it.

TheFranchizeSLB

Get her tuned congrats! just push that eco button off when you get in! It'll become automatic to you!!

MBmemphis

tune the car already!!!!

I actually use the height adjust frequently as it helps with approach angles to some of the driveways and parking entry around town

Suppaa Mario

Did you tune it yet? Curious if it adds too much wear on other components .

VirtualRain

Suppaa Mario

Let me know how that works out. I am debating about it as well.
