New Dashboard Icon showed up
 

I left my house this morning and the car was in comfort mode and saw a engine logo with the number 4 on my digital dash. What exactly is this? Is this the icon showing me the car shut down a cylinder bank for fuel economy when the car is on eco mode. First time I noticed it.

Yup, 4 cylinder mode.

Better do not exceed 30mph and visit a dealer.

just kidding. This is a part of the start/stop system that allows you to save gas on a freeway and cut off 4 cylinders.

Read the manual, please. :zoom:

it means you are clear to takeoff on runway 4 :)

I like seeing that symbol when I am trying to balance out the universe and the time I spent in Sport or Sport plus mode... Next best icon to see is the sailboat, for "glide" mode!

Yep, you have to be in C for it to go to four-cylinders. We call it the "wife is driving icon."

I have never seen this Glide icon you speak of. I'm wondering if it may in fact be my driving style?

I believe it is to reduce both fuel consumption and emissions.

Sadly, the 4 cylinder mode does not activate reliably when cruise control is engaged, same for coasting mode.

On Glide: Remembering my read of the manual, I think you have to be in Individual mode, with the auto start/ stop enabled.. In a scenario such as driving on a road and letting completely off the accelerator to anticipate a stop or merge etc, the drive train/trans will disconnect from the engine and glide, further reducing fuel consumption. if you accelerate or brake, drive train will be enabled ending glide. Amazing how smooth these transitions are... In glide, depending on your dash layout, and options you are scrolled on you will see a sail boat icon pop up. I often see one near E, I, P, R icons are for the trans settings. But it sometime will say "Glide Mode" across the Trip functions if you are on the MPG tracker/ scale view.

works for me only in comfy mode

Odd. I've never seen it in C mode, only I mode like the book says. V4 icon in C but Sailboat in I. Maybe a 2019 thing?

I tried to go to glide on C on the way to work and it will not go to glide in my normal glide parts of my commute. I will stick to I mode - as for me I have it set to be the same as comfy mode, but with flaps open. simple enough. Thanks!

sailboat icon ? odd ! ... My dash shows only this one on all my modes ... Hmmm. :)

it depends on what settings you are using for "I" mode. Mine "I" mode is "no excuses mode" and everything is in "sport+" because I'm too lazy to switch modes all the way down to "sport+".

Make sure that the "start/stop" system is "on" while you are in comfy mode and transmission is in "D" - not manual. Then go to a freeway (or any roads that you can drive 35mph and over) with a slight downhill and push your acceleration pedal not too hard but let it go faster sharply than release the gas pedal and it should go into "sailboat" mode. Also, you should not have anyone ahead of your car because distronic is checking road and if there is any car ahead too close will not allow to "slide". Also, do not touch the brake.

Nope. I've done a lot of experimenting over another 1,000 miles and my car will only go into Sailboat if it's in I. Of course, I must be set to C settings. In I configured the same as C, I get the Sailboat icon (replacing "9" with a Performance display that shows current gear) when I let off the gas on the freeway. It's very easy to trigger. In C, it never does.

This matches what my book states. It's actually kind of odd because the kind of driver who really cares about mileage (I'm thinking about my wife) never reads the manual (I'm thinking about my wife) and would never discover the kind of arcane setting. The reason it's so hard to get to is that on all other models, even the E53, there's an E mode that enables coasting (Sailboat). When they did away with E on the E63 they obviously forgot that they orphaned coast mode. The I-set-like-C hack is what a typical programmer would dream up.

If people really see Sailboat in C, it must be a function of a different version of management coding. But on mine, it won't coast in C.

My car shows a sailboat in C for sure

I think it depends on the gauge configuration. I use progressive typically, and when not doing anything interesting have the left side of the display set up to show the trip info with instantaneous/average fuel economy. In that mode the sailboat doesn't show on the bottom of the screen that I've noticed. Rather, "Gliding Mode" is displayed in the left hand display in the trip info by the fuel consumption bar.

I said it depends on your settings.

Every morning while I'm doing my commute on the freeway to the work I'm driving in "C" mode and almost 1/2 of the way I'm driving in "Sailboat" mode cause driving down from the hill in the toll lane. btw I've never tried to launch sailboat mode in any different modes besides "C".

Have no idea what's broken in your car.

Since the behavior matches the manual, I don't think anything's broken. Sounds more like a engine management change in later builds.

It's also pretty neat how it's smart about not coasting on a down grade that's steep enough to need engine braking. I live on a mountain road and don't see the sailboat when heading down. It only coasts on gentle slopes or flat roads. But it most definitely does it consistently in I and not in C.

What's build date for your car?

December 2018.
